Patent Application
20200057102
A press-fit, interference fit, or friction fit, is a physical fastening between two parts achieved by friction after the parts are pushed together, rather than by applying a fastener or adhesive. Press-fit connectors are used in the electronics industry by circuit board manufacturers, where press-fit connections allow a manufacturer to avoid, for instance, soldering a connector to a circuit board. In this context, a press-fit connection is typically formed when a pin is pressed into, or fitted into, a plated through-hole in the circuit board. The use of press-fit connectors in circuit board assemblies is pervasive today in the electronics industry.
Press-fit connectors can include solid pins or compliant pins. Today, most press-fit connectors use compliant pin technology, since the pins require less force during the insertion process, which causes less damage to the circuit board plated through-holes, and produces more reliable connections. Press-fit connectors are used in a variety of applications including, for instance, in data and communication applications. For many applications, the press-fit pins are continually becoming smaller. Due to ever-smaller features, the retention force and seal of the press-fit pin to the plated through-hole is becoming more susceptible to failure.
Certain shortcomings of the prior art are overcome and additional advantages are provided through, in one or more aspects, the provision of a method for facilitating circuit board assembly fabrication. The method includes identifying a press-fit-connector-to-circuit board connection of a circuit board assembly for testing. The press-fit connector includes one or more press-fit pins, and the circuit board includes multiple plated through-holes. The one or more press-fit pins are press-fit into one or more corresponding plated through-holes of the multiple plated through-holes at a first surface of the circuit board. In addition, the method includes applying, at a second surface of the circuit board, an electrically insulative liquid to the one or more corresponding plated through-holes with the one or more press-fit pins, where the first surface and the second surface of the circuit board are opposite surfaces of the circuit board. The one or more press-fit pins within the one or more corresponding plated through-holes are tested to identify a connection failure, where the electrically insulative liquid applied to the one or more corresponding plated through-holes at the second surface of the circuit board facilitates detection of the connection failure, and the identified connection failure can be corrected through an adjustment to the circuit board assembly fabrication.
In another aspect, a system is provided for facilitating circuit board assembly fabrication. The system includes a test controller configured to perform a method of facilitating circuit board assembly fabrication. The test controller identifies a press-fit-connector-to-circuit board connection of the circuit board assembly for testing, where the press-fit-connector includes one or more press-fit pins, and the circuit board includes multiple plated through-holes, the one or more press-fit pins being press-fit into one or more corresponding plated through-holes of the multiple plated through-holes at a first surface of the circuit board, and applies, at a second surface of the circuit board, an electrically insulative liquid to the one or more corresponding plated through-holes with the one or more press-fit pins, where the first surface and the second surface of the circuit board are opposite surfaces of the circuit board. Further, the test controller tests connection of the one or more press-fit pins to the one or more corresponding plated through-holes to identify a connection failure, where the electrically insulative liquid facilitates identifying the connection failure, and the identified connection failure can be corrected through an adjustment to the circuit board assembly fabrication.
In a further aspect, a computer program product for facilitating circuit board assembly fabrication is provided. The computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a processor to cause the processor to identify a press-fit-connector-to-circuit board connection of the circuit board assembly for testing. The press-fit connector includes one or more press-fit pins, and the circuit board includes multiple plated through-holes. The one or more press-fit pins are press-fit into one or more corresponding plated through-holes of the multiple plated through-holes at a first surface of the circuit board. The program instructions are executable by the processor to further cause the processor to apply, at a second surface of the circuit board, an electrically insulative liquid to the one or more corresponding plated through-holes with the one or more press-fit pins, where the first surface and the second surface of the circuit board are opposite surfaces of the circuit board, and to test connection of the one or more press-fit pins to the one or more corresponding plated through-holes to identify a connection failure. The electrically insulative liquid facilitates identifying the connection failure, and the identified connection failure can be corrected through an adjustment to the circuit board assembly fabrication.

As computing systems, such as server systems, continue to progress, more press-fit connectors are being used, and the press-fit pins of the connectors continue to become smaller and smaller. Due to their small feature size, the retention force and gas-tight seal for electrical connection between a press-fit pin and a plated through-hole of a circuit board is becoming more susceptible to failure. Disclosed herein, in various aspects, are techniques for evaluating a low-force, press-fit-connector-to-board system to determine whether the connector system can maintain retention and/or electrical contact functionality and reliability over time by using an electrically insulative liquid as part of the testing process. In typical testing approaches, pin measurements are averaged through a common pressing or testing of the connector system, while the method, system and computer program product disclosed herein advantageously allow identification of individual press-fit-pin-to-plated-through-hole connections with defective or marginal contact force, making the connection(s) susceptible to failure over time.
Disclosed herein is a novel approach to facilitating circuit board assembly test and fabrication. In particular, disclosed are novel methods, systems and computer program products which facilitate circuit board assembly fabrication by testing the retention and/or electrical connection of a press-fit connector system of the circuit board assembly, where the circuit board assembly has one or more press-fit connector systems including a press-fit connector press-fit or interference-fit to respective plated through-holes of the circuit board for electrical and mechanical connection of the connector to the circuit board. The processing disclosed can be particularly advantageous during qualification testing of a circuit board assembly, or failure analysis of a circuit board assembly, having one or more press-fit connector systems. The processes disclosed advantageously allow for early detection of a circuit board assembly fabrication defect or error, and thus, correction of the defect to facilitate fabricating of the circuit board.
In general, the methods, systems and computer program products disclosed facilitate circuit board assembly fabrication by identifying a press-fit-connector-to-circuit board connection of the circuit board assembly for testing. The press-fit connector includes one or more press-fit pins, and the circuit board includes multiple plated through-holes. The one or more press-fit pins are press-fit into one or more corresponding plated through-holes of the multiple plated through-holes at a first surface of the circuit board. An electrically insulative liquid is applied at a second surface of the circuit board to the one or more corresponding plated through-holes with the press-fit pins. The first surface and the second surface of the circuit board are opposite surfaces of the circuit board. Connection of the one or more press-fit pins to the one or more corresponding plated through-holes is tested to identify a connection failure, with the electrically insulative liquid facilitating identifying the connection failure. The identified connection failure is correctable through a fabrication change to the circuit board assembly. In one or more implementations, the process includes determining a fabrication change to the circuit board assembly to correct the connection failure, and implementing the change.
In one or more embodiments, the process may further include waiting an interval of time after applying the electrically insulative liquid to allow the electrically insulative liquid to penetrate the one or more corresponding plated through-holes via, at least in part, capillary action. Further, in one or more embodiments, the process includes orienting the circuit board assembly to allow gravity to assist in penetration of electrically insulative liquid into the one or more corresponding plated through-holes with the one or more press-fit pins.
In one embodiment, the testing includes testing a press-fit seal between a press-fit pin of the one or more press-fit pins and a corresponding plated through-hole of the one or more corresponding plated through-holes of the circuit board. The testing can include applying an electrical signal to the press-fit pin to electrically evaluate the connection in the presence of the electrically insulative liquid applied at the second surface of the circuit board. Further, or alternatively, the testing can include retention testing the press-fit pin within the corresponding plated through-hole to mechanically evaluate the connection in the presence of the electrically insulative liquid applied at the second surface of the circuit board.
In one or more implementations, the testing includes continually monitoring electrical connection of the one or more press-fit pins to the one or more corresponding plated through-holes during a reliability stressing of the circuit board assembly. The reliability stressing can include one or more of a retention test, a mechanical shock test, a mechanical vibration test, a G-force test, a vacuum test or assist, and/or a temperature test.
In one or more embodiments, the applying of the electrically insulative liquid includes applying the electrically insulative liquid to, at least in part, the second surface of the circuit board, including over the one or more plated through-holes. Further, in one or more embodiments, applying of the electrically insulative liquid includes using an aerosol application of the electrically insulative liquid, using a spray application of the electrically insulative liquid, using a brush application of the electrically insulative liquid, using a droplet application of the electrically insulative liquid, and/or using a sponge application of the electrically insulative liquid. In one or more embodiments, the electrically insulative liquid is an oil or a refrigerant selected to penetrate the one or more corresponding plated through-holes via at least, capillary action. In one or more embodiments, the electrically insulative liquid is a silicone oil, or in one or more other embodiments, is an insulating fluorocarbon-based fluid, such as Fluorinert™ FC-70 electronic liquid (offered by 3M Company of St. Paul, Minn. (USA)).
By way of example,
An electrically insulative liquid is applied to the plated through-hole(s) with the attached press-fit connector 110. In one or more embodiments, this includes applying the electrically insulative liquid to the second surface of the circuit board, opposite from the first surface to which the press-fit-connector-to-circuit board connection is made. The electrically insulative liquid is applied to test whether the liquid will penetrate the press-fit seal between the respective press-fit pin(s) and the corresponding plated through-hole(s). Advantageously, this process can be used in a variety of settings to facilitate circuit board assembly fabrication. For instance, the approach can be used during qualification testing to ensure workmanship criteria and reliability is met, and/or during failure analysis to determine why a circuit board assembly has failed.
In one or more embodiments, the electrically insulative liquid is in oil, such as silicone oil. Silicone oil readily wicks or penetrates via capillary action, the plated through-holes, and comes in contact with the press-fit pin within the plated through-hole, as well as the plated through-hole surfaces. The capillary action of the silicone oil in the plated through-hole is high, and the oil collects contaminants that can cause cross-linking of the silicone monomer. The cross-linking makes the oil more insulating. For a failure of a circuit board assembly to occur, a situation may require an event to dislodge or slightly disturb the original press-fit seal or interface between the press-fit pin and the plated through-hole, allowing the resistant material to degrade the resulting contact surface between the two structures. Other electrically insulative liquids can also be used, such as an electrically insulating fluorocarbon-based fluid, such as the above-noted Fluorinert™ FC-70.
The electrically insulative liquid can be applied using multiple techniques, including, for instance, aerosol, spraying, brushing, droplet application, sponge application, etc. Further, the electrically insulative liquid can be applied before and/or after reliability or fragility stress cycles, and allows for continuous monitoring of the electrical connection during application of the electrically insulative liquid. Fragility testing can include mechanical plugging, shock and vibration stressing. Depending on the orientation of the circuit board assembly, the circuit board assembly can be inverted to leverage gravitational forces to facilitate penetration of the electrically insulative liquid into the corresponding plated through-holes. The approach can be used in combination with more aggressive testing to, for instance, pull a vacuum on the circuit board assembly, or applying of a heat gradient or temperature cycling across the circuit board assembly through various thermal methods. Such approaches will also facilitate increasing in the capillary action or forces to facilitate penetration of the electrically insulative liquid into the corresponding plated through-holes with the press-fit pins.
After applying the electrically insulative liquid, the connector-to-board connection can be tested to verify functionality 120. The testing can include electrical testing of the press-fit pins to corresponding plated through-hole connections, as well as retention testing of the press-fit connector system to the circuit board. For instance, the electrically insulative liquid can be used to determine whether there is a liquid or gas-tight seal between the press-fit connector and the plated through-hole (such as a copper plated through-hole). If there is not a gas-tight seal, then oxidation can occur over time resulting in loss of electrical connection. Thus, the processing disclosed provides an approach for early detection of such issues, and therefore, facilitates the circuit board assembly fabrication. Assuming a press-fit seal between a press-fit pin and the corresponding plated through-hole is other than a gas tight seal, then the electrically insulative liquid will penetrate between the two structures, resulting in creating an opening between the two structures, and allowing for identification of a connection failure 130. As noted, a vacuum or thermal gradient process can be utilized for a more aggressive approach to facilitate liquid penetration into the plated through-holes to press-fit pin interfaces.
After identifying a connection failure, the process can include determining a cause for the connection failure 140. For instance, the dimensions of the respective press-fit pin and corresponding plated through-hole can be ascertained and evaluated to determine whether the dimensions are within specification. If so, it may be necessary to re-specify one or both structures for the fabrication process. In another implementation, once a connection failure is identified, processing can determine where the electrical loss occurred, that is, which particular pin has the connection problem. Follow-up cross-section testing can be used to determine which dimensions, if any, are out of specification. Once the cause for the connection failure is determined, then an adjustment can be initiated for the manufacturing process of the circuit board and/or the press-fit connector to correct the determined cause(s) of the connection failure 150. In one or more embodiments, this can include initiating a fabrication change to the circuit board assembly to, for instance, change a dimension of the press-fit pin and/or the plated through-hole to correct the failure condition. Advantageously the processing disclosed herein determines a particular press-fit pin to plate a through-hole via connection at issue, and allows for detection of a problem much more quickly than otherwise possible using other techniques. By being able to detect potentially deficient connections early, the circuit board assembly fabrication process can be adjusted to ensure performance and reliability of the resultant circuit board assembly.

One or more aspects may relate to or use cloud computing.
It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
In addition to the above, one or more aspects may be provided, offered, deployed, managed, serviced, etc. by a service provider who offers management of customer environments. For instance, the service provider can create, maintain, support, etc. computer code and/or a computer infrastructure that performs one or more aspects for one or more customers. In return, the service provider may receive payment from the customer under a subscription and/or fee agreement, as examples. Additionally or alternatively, the service provider may receive payment from the sale of advertising content to one or more third parties.
In one aspect, an application may be deployed for performing one or more embodiments. As one example, the deploying of an application comprises providing computer infrastructure operable to perform one or more embodiments.
As a further aspect, a computing infrastructure may be deployed comprising integrating computer readable code into a computing system, in which the code in combination with the computing system is capable of performing one or more embodiments.
As yet a further aspect, a process for integrating computing infrastructure comprising integrating computer readable code into a computer system may be provided. The computer system comprises a computer readable medium, in which the computer medium comprises one or more embodiments. The code in combination with the computer system is capable of performing one or more embodiments.
Although various embodiments are described above, these are only examples. For example, other types of devices and/or tracking components may be used in one or more embodiments. Many variations are possible.
Further, other types of computing environments can benefit and be used. As an example, a data processing system suitable for storing and/or executing program code is usable that includes at least two processors coupled directly or indirectly to memory elements through a system bus. The memory elements include, for instance, local memory employed during actual execution of the program code, bulk storage, and cache memory which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.
Input/Output or I/O devices (including, but not limited to, keyboards, displays, pointing devices, DASD, tape, CDs, DVDs, thumb drives and other memory media, etc.) can be coupled to the system either directly or through intervening I/O controllers. Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modems, and Ethernet cards are just a few of the available types of network adapters.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”), and “contain” (and any form contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, a method or device that “comprises”, “has”, “includes” or “contains” one or more steps or elements possesses those one or more steps or elements, but is not limited to possessing only those one or more steps or elements. Likewise, a step of a method or an element of a device that “comprises”, “has”, “includes” or “contains” one or more features possesses those one or more features, but is not limited to possessing only those one or more features. Furthermore, a device or structure that is configured in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
