This application is based on and claims the benefit of priority from Japanese Patent Application No. 2015-233840 filed on Nov. 30, 2015. The entire disclosures of all of the above applications are incorporated herein by reference.
The present invention relates to a heater plate, an apparatus for manufacturing a heat flux sensor using the heater plate, a method of manufacturing the heater plate and an apparatus for manufacturing the heater plate; the heater plate is capable of, while heating a sheet-like inspection object that has a plurality of terminals capable of outputting a signal, externally outputting the signal outputted by the terminals.
Conventionally, there have been known heat flux sensors that measure heat flux which is defined as the quantity of heat crossing per unit area per unit time from one side to the other side. For example, in Patent Document 1, there is described a heat flux sensor that includes: a plate-like substrate having a plurality of via holes; and output circuit sections respectively on two major surfaces of the substrate which are electrically connected via electrically-conductive layers formed in the via holes and output voltages generated according to the magnitude of the heat quantity flowing from one side to the other side of the substrate.
[PATENT DOCUMENT 1] Japanese Patent Application Publication No. JP2007208262A
In the heat flux sensor described in Patent Document 1, a plurality of output circuit sections, which output signals of the heat flux sensor, are provided on a plate-like member that is obtained by laminating a soft film of a polyimide or the like constituting the substrate and an insulating layer formed of a solder resist or the like. Therefore, in inspecting the characteristics of the heat flux sensor during the manufacture of the heat flux sensor described in Patent Document 1, it is necessary to accurately measure the voltages respectively outputted by the plurality of output circuit sections while causing a heat flow of a predetermined magnitude to flow from one side to the other side of the heat flux sensor.
In causing a predetermined quantity of heat to flow through the heat flux sensor, a heater for heating is provided on one side of the heat flux sensor while a cooling section is provided on the other side of the heat flux sensor. Consequently, a heat flow is formed which flows from the one side to the other side of the heat flux sensor. At this time, the characteristics of the heat flux sensor are inspected based on the relationship between the voltages outputted by the heat flux sensor, which is sandwiched between the heater and the cooling section, and the magnitude of the heat quantity flowing through the heat flux sensor. The magnitude of the heat quantity flowing through the heat flux sensor can be calculated based on the electric power supplied to the heater. However, heat generated by the heater not only flows to the cooling section, but also diffuses in every direction as viewed from the heater. Therefore, it is difficult to accurately determine the magnitude of the heat quantity actually passing through the heat flux sensor.
Accordingly, one may consider inspecting the characteristics of the heat flux sensor with the heater formed as thin as possible into a sheet-like shape so that diffusion of the heat is negligible in directions other than both the direction toward the cooling section and the direction toward the opposite side to the cooling section as viewed from the heater.
At this time, to ensure thermal insulation while improving the adherence between the heater and the heat flux sensor, a support made of an elastic material may be provided on the opposite side of the heater to the cooling section. However, when external inspection probes are pressed on the output circuit sections during inspection of the characteristics of the heat flux sensor, the support may be bent by the pressing force, forming a gap between the heater and the heat flux sensor. Consequently, it may become impossible to have the heater and the heat flux sensor sufficiently adhered to each other.
Moreover, in the case where the plurality of output circuit sections are provided on the single substrate as in the heat flux sensor described in Patent Document 1, the amount of bending of the support would be large and thus the adherence between the heater and the heat flux sensor would be further deteriorated since the plurality of inspection probes are respectively pressed on the plurality of output circuit sections. Consequently, it would become impossible to accurately determine the quantity of heat flowing through the heat flux sensor, thus lowering the inspection accuracy.
The present invention has been made in view of the above problems. It is therefore an object of the present invention to provide a heater plate capable of, while accurately heating an inspection object having terminals capable of outputting a signal and thereby causing a predetermined quantity of heat to flow through the inspection object, reliably externally outputting the signal outputted by the terminals.
A heater plate according to the present invention is capable of, while heating a sheet-like inspection object that has terminals capable of outputting a signal, outputting to an external device or an external circuit the signal outputted by the terminals. The heater plate includes a sheet-like heating member, a protective film, an output circuit section and a protruding portion forming film.
The sheet-like heating member generates heat upon being energized.
The protective film is provided on the side of one major surface of the sheet-like heating member to protect the sheet-like heating member.
The output circuit section is provided on a surface of the protective film on the opposite side to the sheet-like heating member. The output circuit section has protruding portions and external output portions. The protruding portions protrude in a direction opposite to the sheet-like heating member so as to be capable of abutting the terminals respectively. The external output portions are respectively electrically connected with the protruding portions and capable of externally outputting the signal that is inputted to the protruding portions.
The protruding portion forming film is provided between the protective film and the sheet-like heating member. The protruding portion forming film has protrusions formed at positions corresponding to the protruding portions.
The sheet-like heating member, the protective film, the output circuit section and the protruding portion forming film are integrally formed into one piece.
In the heater plate according to the present invention, the protruding portion forming film, which is provided between the protective film and the sheet-like heating member, has the protrusions formed at the positions corresponding to the protruding portions of the output circuit section. Consequently, those portions of the protective film and those portions of the output circuit section which correspond to the positions of the protrusions protrude along the shape of the protrusions in the direction opposite to the sheet-like heating member, forming the protruding portions of the output circuit section. The protruding portions of the output circuit section can be formed into a desired shape by forming the protrusions into a desired shape; therefore, it is possible to reliably make electrical connection between the terminals of the inspection object and the protruding portions while adhering the heater plate to the inspection object and thereby reliably transferring the heat generated by the heating element to the inspection object. Accordingly, the heater plate according to the present invention can reliably externally output the signal outputted by the terminals while supplying a predetermined quantity of heat to the inspection object.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A heater plate according to one embodiment of the present invention, an apparatus for manufacturing a heat flux sensor using the heater plate, a method of manufacturing the heater plate and an apparatus for manufacturing the heater plate will be described with reference to

The output circuit section 25 has a plurality of protruding portions 251, a plurality of wiring portions 252 and a plurality of external output portions 253. The output circuit section 25 is formed by patterning a single sheet of metal.
The protruding portions 251 are formed to be capable of respectively abutting the terminals 141 and 151 of the heat flux sensors 10 formed in the sensor sheet 8. The protruding portions 251 protrude in the direction opposite to the sheet-like heating member 200. In the present embodiment, there are formed 48 protruding portions 251 with respect to the 24 heat flux sensors 10 formed in the sensor sheet 8.
The wiring portions 252, the number of which is equal to the number of the protruding portions 251, are formed to be respectively electrically connected to the protruding portions 251. Specifically, in the present embodiment, 48 wiring portions 252 are formed with respect to the sensor sheet 8. The wiring portions 252 are formed in the shape of a thin film on the surface 231 of the protective film 23. Moreover, the wiring portions 252 are formed so as to extend from the protruding portions 251 toward the outer periphery of the heater plate 20. At ends of the wiring portions 252 on the opposite side to the protruding portions 251, there are respectively provided the external output portions 253.
The external output portions 253, the number of which is equal to the number of the wiring portions 252, are formed to be respectively electrically connected to the wiring portions 252.

The protruding portion forming film 26 is provided between the protective film 23 and the sheet-like heating member 200. The protruding portion forming film 26 is formed of a material which has higher flowability at a predetermined temperature than the material of the protective film 23, such as PEI. The protruding portion forming film 26 has protrusions 261 formed at positions corresponding to the protruding portions 251 of the output circuit section 25.
As shown in
The temperature detecting section 45 is configured to be capable of detecting the temperature on the opposite side of the heater plate 20 to the sensor sheet 8. In the present embodiment, the temperature detecting section 45 includes a heater support 46, a sheet support 47, a heat flux detecting sheet 9 and a temperature calculating section 48.
The heater support 46 is provided on the opposite side of the heater plate 20 to the sensor sheet 8. The heater support 46 supports the heater plate 20.
The sheet support 47 supports the heat flux detecting sheet 9 between it and the heater support 46.
The heat flux detecting sheet 9 is a sensor sheet which is manufactured in the same lot as the sensor sheet 8 whose characteristics are inspected by the inspection apparatus 1. The heat flux detecting sheet 9 detects the magnitude of the heat quantity flowing from the heater plate 20 to the sheet support 47. The heat flux detecting sheet 9 outputs a voltage according to the magnitude of the heat quantity; the voltage is outputted to the temperature calculating section 48.
The temperature calculating section 48 calculates, based on the voltage outputted by the heat flux detecting sheet 9, the magnitude of the heat quantity flowing from the heater plate 20 to the opposite side to the sensor sheet 8. The temperature calculating section 48 outputs a signal in accordance with the calculated magnitude of the heat quantity to the temperature controlling section 50.
The temperature controlling section 50 is electrically connected with the heater plate 20, the cooling section 40 and the temperature detecting section 45. To the temperature controlling section 50, there is inputted the signal outputted by the temperature detecting section 45. Based on the signal, the temperature controlling section 50 controls both the degree of heating by the heating plate 20 and the degree of cooling by the cooling section 40.
In the inspection apparatus 1, the temperature controlling section 50 controls the heater plate 20 and the cooling section 40 to have the magnitude of the heat quantity flowing from the heater plate 20 to the opposite side to the sensor sheet 8 equal to 0, i.e., to have the temperature of the temperature detecting section 45 equal to the temperature of the environment where the inspection apparatus 1 is placed. Consequently, all of the heat generated in the heater plate 20 can be considered as flowing to the cooling section 40 via the heat flux sensors 10; thus it is possible to accurately calculate the magnitude of the heat flow through the heat flux sensors 10 based on the voltage applied to the heating element 21 of the heater plate 20.
The characteristic measuring section 60 is electrically connected with the sensor sheet 8. The characteristic measuring section 60 derives, based on the signals outputted by the sensor sheet 8, the relationship between the magnitude of the heat flux and the outputted voltage for each of the heat flux sensors 10 formed in the sensor sheet 8. The derived results represent the characteristics of the heat flux sensors 10.
Next, a manufacturing apparatus and a manufacturing method of the heater plate 20 will be described.
First, a heater plate manufacturing apparatus 2 will be described with reference to
The press table 70 is provided on the lower side of the heater plate manufacturing apparatus 2. The press table 70 is constituted of a press table main body 71 and a heater 72.
The press table main body 71 is formed to be capable of allowing a lower resin film 34 forming the protective film 24 of the heater plate 20, the sheet-like heating member 200, a flow film 36 forming the protruding portion forming film 26 of the heater plate 20, an upper resin film 33 which corresponds to a “coating film” forming the protective film 23 of the heater plate 20, and a metal sheet 35 forming the output circuit section 25 of the heater plate 20 to be sequentially placed in this order on an upper surface 711 of the press table main body 71. Hereinafter, for the sake of convenience, the laminate of the lower resin film 34, the sheet-like heating member 200, the flow film 36, the upper resin film 33 and the metal sheet 35 placed on the press table main body 71 will be referred to as heater plate forming laminate 300.
The heater 72 is provided on the opposite side of the press table main body 71 to the heater plate forming laminate 300. The heater 72 is configured to be capable of heating the heater plate forming laminate 300 via the press table main body 71. In the heater 72, there is provided a temperature sensor which is not shown in the figures; the temperature of the heater 72 is controlled based on the detection results of the temperature sensor.
The press member 80 is provided so as to be reciprocable in the vertical direction with respect to the press table 70. The press member 80 is constituted of a press main body 81, a processing portion 82 and a heater 83.
The press main body 81 is formed of a material which has a size capable of pressing the entire heater plate forming laminate 300 and whose thermal conductivity is relatively high.
The processing portion 82 is provided on a surface 811 of the press main body 81 on the press table 70 side. As shown in
The heater 83 is provided on the opposite side of the press main body 81 to the heater plate forming laminate 300. The heater 83 is configured to be capable of heating the processing portion 82 via the press main body 81. In the heater 83, there is provided a temperature sensor which is not shown in the figures; the temperature of the heater 83 is controlled based on the detection results of the temperature sensor.
The drive section 90 is connected with both the press table 70 and the press member 80. The drive section 90 is configured to generate a driving force capable of driving the press member 80 with respect to the press table 70 and transmit the driving force to the press member 80. Moreover, the drive section 90 is capable of supplying the heaters 72 and 83 with electric power for generating heat.
Next, the method of manufacturing the heater plate 20 using the heater plate manufacturing apparatus 2 will be described with reference to
First, in a sheet-like heating member forming step S101, the sheet-like heating member 200 is formed. Specifically, as shown in
Next, in a laminate forming step S102, as shown in
The lower resin film 34 is formed of PEEK into the shape of a flat plate. The lower resin film 34 will constitute the protective film 24 of the heater plate 20.
The flow film 36 is provided between the sheet-like heating member 200 and the upper resin film 33. The flow film 36 is formed of PEI, which has higher flowability at the predetermined temperature than the upper resin film 33, into the shape of a flat plate. The flow film 36 will constitute the protruding portion forming film 26 of the heater plate 20.
The upper resin film 33 is formed of PEEK into the shape of a flat plate. The upper resin film 33 is provided so as to cover the flow film 36. The upper resin film 33 will constitute the protective film 23 of the heater plate 20.
The metal sheet 35 is provided on the opposite side of the upper resin film 33 to the sheet-like heating member 200. The metal sheet 35 is formed of a metal that is patterned so as to form a circuit on the upper resin film 33. The metal sheet 35 will constitute the output circuit section 25 of the heater plate 20.
Next, in a protruding portion forming step S103, by the press table 70 and the press member 80, the heater plate forming laminate 300 is pressed while being heated. Specifically, the heater plate forming laminate 300 is pressed from both sides thereof under a pressure of, for example, 6 MPa with the temperatures of the press table 70 and the press member 80 kept by the respective temperature sensors at a predetermined temperature, e.g., 230 degrees.
Upon the heater plate forming laminate 300 being heated by the press table 70 and the press member 80 to 230 degrees, the flow film 36 is caused to have flowability. At this time, part of the flow film 36 sandwiched between the sheet-like heating member 200 and the upper resin film 33 moves, by the pressure under which the heater plate forming laminate 300 is pressed, to the recesses 821 of the press member 80. Consequently, as shown in
As above, in the present embodiment, the protruding portions 351 are formed in the metal sheet 35 by pressing the heater plate forming laminate 300 while heating the same. Consequently, the heater plate 20 is manufactured which has the protective film 24 constituted of the lower resin film 34, the protruding portion forming film 26 constituted of the flow film 36, the protective film 23 constituted of the upper resin film 33 and the protruding portions 251 of the output circuit section 25 constituted of the protruding portions 351 of the metal sheet 35.
In the heater plate 20, the protruding portion forming film 26, which is provided between the protective film 23 and the sheet-like heating member 200, has the protrusions 261 formed at the positions corresponding to the protruding portions 251 of the output circuit section 25. Consequently, those portions of the protective film 23 and those portions of the output circuit section 25 which correspond to the positions of the protrusions 261 protrude, forming the protruding portions 251. Since the protruding portions 251 can be formed into a desired shape by forming the protrusions 261 into a desired shape, it is possible to ensure electrical connection between the terminals 141 and 151 of the heat flux sensors 10 and the protruding portions 251. Moreover, the heating element 21, which heats the heat flux sensors 10, is formed integrally with the output circuit section 25 that has the protruding portions 251; therefore, by adhering the heater plate 20 to the heat flux sensors 10, it is possible to reliably bring the protruding portions 251 into abutment with the terminals 141 and 151 while reliably transferring the heat generated by the heating element 21 to the heat flux sensors 10. Accordingly, the heater plate 20 can reliably externally output the signals outputted by the terminals 141 and 151 while supplying a predetermined heat quantity to the heat flux sensors 10.
In the heater plate 20, the protruding portion forming film 26, which has the protrusions 261 for forming the protruding portions 251, is formed of PEI whose flowability at 230 degrees which is the “predetermined temperature” is higher than the flowability of the protective film 23 at the same temperature. Consequently, in manufacturing the heater plate 20, it is possible to relatively easily form the protrusions 261 into a desired shape. Accordingly, it is possible to reliably externally output the signals outputted by the terminals 141 and 151 by forming the protruding portions 251 to have a height at which the protruding portions 251 can be reliably brought into contact with the terminals 141 and 151.
Moreover, in the manufacturing method of the heater plate 20 according to the present embodiment, the press member 80, which has the recesses 821 at the positions corresponding to the protruding portions 251, is used to press the heater plate forming laminate 300 while heating the same. Consequently, of the flow film 36 that is caused by heating to have flowability, those portions which correspond to the recesses 821 move into the recesses 821, forming the protrusions 361. Moreover, with formation of the protrusions 361, those portions 331 of the upper resin film 33 which respectively correspond to the protrusions 361 and those portions 351 of the metal sheet 35 which respectively correspond to the portions 331 of the upper resin film 33 protrude to form the protruding portions 251 of the heater plate 20. Therefore, it is possible to accurately adjust the height H351 of the protruding portions 251 to a desired height by adjusting the depth D821 of the recesses 821 when machining the recesses 821. Consequently, it is possible to manufacture the heater plate 20 which has the protrusions 251 capable of reliably abutting the terminals 141 and 151 of the heat flux sensors 10.
Moreover, in the heater plate manufacturing apparatus 2, the processing portion 82 constituting the press member 80 is formed separately from the press main body 81. The through-holes formed in the processing portion 82 constitute the recesses 821 for forming the protruding portions 251; therefore, it is possible to improve the machining accuracy of the recesses 821. Accordingly, it is possible to accurately set the height H351 of the protruding portions 351 of the metal sheet 35 which represents the height of the protruding portions 251 in the heater plate 20.
In the above-described embodiment, the heater plate is employed in the apparatus for inspecting the characteristics of the heat flux sensors that are formed in a sheet-like shape. However, the heater plate may also be applied to other apparatuses that inspect a sheet-like inspection object, which has terminals capable of outputting a signal, by externally outputting the signal outputted by the terminals while heating the inspection object.
In the above-described embodiment, when the heater plate forming laminate is pressed by the press table and the press member, the protruding portions of the metal sheet are formed so that the height from the press member-side surfaces of the non-protruding portions of the metal sheet to the press main body-side vertexes of the protruding portions is substantially equal to the depth of the recesses of the press member. However, the metal sheet may alternatively be pressed so that the protruding portions thereof protrude more than the depth of the recesses. In this case, as shown in
In the above-described embodiment, the heat flux sensors have the configuration as shown in
In the above-described embodiment, the protruding portion forming film of the heater plate is formed of PEI while the protective films of the heater plate are formed of PEEK. However, materials for forming the protruding portion forming film and the protective films are not limited to the above materials. Moreover, though it is preferable that the protruding portion forming film has higher flowability at the predetermined temperature than the protective films, materials for forming the protruding portion forming film and the protective films do not necessarily satisfy the above condition.
In the above-described embodiment, in pressing the heater plate forming laminate while heating the same, the heater plate forming laminate is pressed under the pressure of 6 MPa while the press table and the press member are heated to 230 degrees. However, the temperature of heating the heater plate forming laminate and the pressure are not limited to the above values. The temperature may be any temperature at which the flow film is flowable whereas the upper resin film is not flowable. Moreover, the pressure may be any pressure under which the flow film in a flowable state can move into the recesses.
In the above-described embodiment, the heater plate has, on the opposite side of the sheet-like heating member to the output circuit section, the protective film for protecting the sheet-like heating member. However, the protective film on the opposite side of the sheet-like heating member to the output circuit section may be omitted.
In the above-described embodiment, the heater of the press table of the heater plate manufacturing apparatus is provided on the opposite side of the press table main body to the heater plate forming laminate. Moreover, the heater of the press member is provided on the opposite side of the press main body to the heater plate forming laminate. However, the positional relationship between the press table main body and the heater of the press table and the positional relationship between the press main body and the heater of the press member are not limited to the above arrangement.
In the above-described embodiment, the sheet-like heating member is constituted of the heating element formed to meander on a plane and the insulating portions formed in the gaps between adjacent portions of the heating element to maintain insulation between the adjacent portions. However, the constitution of the sheet-like heating member is not limited to the above.
In the above-described embodiment, the temperature detecting section calculates the magnitude of the heat flow from the heater plate to the opposite side to the sensor sheet using a sensor sheet which is manufactured in the same lot as the sensor sheet whose characteristics are inspected by the inspection apparatus. However, the configuration of the temperature detecting section is not limited to the above. The temperature detecting section may alternatively detect a temperature using a thermocouple.
In the above-described embodiment, the processing portion constituting the press member is formed separately from the press main body. However, the processing portion may alternatively be formed integrally with the press main body into one piece.
As above, the present invention is not limited to the above-described embodiment and can be implemented in various modes without departing from the spirit of the invention.
