The substrate preheating module is electrically connected to the signal control module and configured to correspond to the substrate carrying module. The chip bonding module is electrically connected to the signal control module and configured to correspond to the substrate carrying module. When the substrate carrying module is optionally configured to be used, the substrate carrying module is allowed to be configured through the signal control module to carry a circuit substrate. When the chip transferring module is optionally configured to be used, the chip transferring module is allowed to be configured through the signal control module to transfer a plurality of chips to the circuit substrate. When the substrate preheating module is optionally configured to be used, the substrate preheating module is allowed to be configured through the signal control module to preheat the circuit substrate at a predetermined preheating temperature, thereby allowing a plurality of soldering materials disposed between each of the chips and the circuit substrate to be preheated at the predetermined preheating temperature that is provided by the substrate preheating module. When the chip bonding module is optionally configured to be used, the chip bonding module is allowed to be configured through the signal control module to instantaneously heat the soldering materials disposed between each of the chips and the circuit substrate at a predetermined heating temperature. When the substrate preheating module and the chip bonding module are optionally configured to be used simultaneously, the substrate preheating module is configured to provide the predetermined preheating temperature, and the chip bonding module is configured to provide the predetermined heating temperature.


In order to solve the above-mentioned problems, another one of the technical aspects adopted by the present disclosure is to provide a chip transferring and bonding device, which includes a signal control module, a substrate carrying module, a chip transferring module, a substrate preheating module and a chip bonding module. The chip transferring module is electrically connected to the signal control module and movably disposed above the substrate carrying module. The substrate preheating module is electrically connected to the signal control module. The chip bonding module is electrically connected to the signal control module. When the substrate preheating module and the chip bonding module are optionally configured to be used simultaneously, the substrate preheating module is configured to provide a predetermined preheating temperature, and the chip bonding module is configured to provide a predetermined heating temperature.


In order to solve the above-mentioned problems, yet another one of the technical aspects adopted by the present disclosure is to provide a chip transferring and bonding method, which includes: carrying a circuit substrate by a substrate carrying module; transferring a plurality of chips to the circuit substrate by a chip transferring module; preheating the circuit substrate at a predetermined preheating temperature by a substrate preheating module, thereby allowing a plurality of soldering materials disposed between each of the chips and the circuit substrate to be preheated at the predetermined preheating temperature that is provided by the substrate preheating module; and during the step of preheating the circuit substrate at the predetermined preheating temperature by the substrate preheating module, instantaneously heating the soldering materials disposed between each of the chips and the circuit substrate at a predetermined heating temperature by a chip bonding module. When the substrate preheating module and the chip bonding module are optionally configured to be used simultaneously, the substrate preheating module is configured to provide the predetermined preheating temperature, and the chip bonding module is configured to provide the predetermined heating temperature.

Referring to FIG. 1 to FIG. 10, the present disclosure provides a chip transferring and bonding device D, which at least includes a signal control module 1, a substrate carrying module 2, a chip transferring module 3, a substrate preheating module 4 and a chip bonding module 5.

It should be noted that when the substrate preheating module 4 and the chip bonding module 5 are optionally (or selectively) configured to be used simultaneously, the substrate preheating module 4 can be configured to directly or indirectly provide a predetermined preheating temperature to the soldering materials S, and the chip bonding module 5 can be configured to directly or indirectly provide a predetermined heating temperature to the soldering materials S. Therefore, when the substrate preheating module 4 and the chip bonding module 5 are optionally configured to be used at the same time, the soldering materials S can be instantaneously (or instantly) and directly heated from the predetermined preheating temperature to the predetermined heating temperature, thereby reducing or avoiding residual stress (or thermal stress) in the soldering area.


First Embodiment

Referring to FIG. 1 to FIG. 6, a first embodiment of the present disclosure provides a chip transferring and bonding device D, which includes a signal control module 1, a substrate carrying module 2, a chip transferring module 3, a substrate preheating module 4 and a chip bonding module 5.


More particularly, referring to FIG. 1 and FIG. 2, the substrate carrying module 2 can be electrically connected to the signal control module 1, and the chip transferring module 3 can be electrically connected to the signal control module 1 and movably disposed above the substrate carrying module 2. For example, the signal control module 1 can be a desktop computer, a laptop computer, a tablet computer or any kind of portable electronic device that at least includes a central processing unit (CPU), a digital signal processor (DSP), a microprocessor (MPU), a microcontroller (MCU) or any kind of signal control chip. Moreover, the substrate carrying module 2 can be a movable clamp, a movable vacuum suction nozzle, or any kind of stage, which can be used to carry any kind of substrate. In addition, the chip transferring module 3 (or the chip moving module, or a chip carrying module) can be a movable clamping jaw, a movable vacuum nozzle, or any kind of chip transferring structure that can be used to transfer the chip from one place to another. It should be noted that when the substrate carrying module 2 is optionally configured to be used, the substrate carrying module 2 can be allowed to be configured through the signal control module 1 to carry a circuit substrate P (or the substrate carrying module 2 can indirectly carry the circuit substrate P through the substrate preheating module 4). In addition, when the chip transferring module 3 is optionally configured to be used, the chip transferring module 3 can be allowed to be configured through the signal control module 1 to transfer a plurality of chips C (such as LED chips or any kind of semiconductor chips, or dies, or electronic components) to the circuit substrate P. More particularly, the chip transferring module 3 can be configured to carry or move a temporary carrying substrate T (such as a glass substrate, a plastic substrate, or a light-transmitting substrate that can be made of any material), and the chips C can be pre-attached to an adhesive layer T100 of the temporary carrying substrate T. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.


More particularly, referring to FIG. 1, FIG. 2 and FIG. 3, the substrate preheating module 4 is electrically connected to the signal control module 1 and configured to correspond to the substrate carrying module 2. For example, when the substrate preheating module 4 is optionally configured to be used, the substrate preheating module 4 can be allowed to be configured through the signal control module 1 to preheat the circuit substrate P at a predetermined preheating temperature (or by a specific preheating temperature), thereby allowing a plurality of soldering materials S that is disposed between each chip C and the circuit substrate P to be preheated at the predetermined preheating temperature that is provided by the substrate preheating module 4. In one of the feasible embodiments, the substrate preheating module 4 includes a heating plate structure 41 (such as a heating structure having at least one heating coil or at least one heater) for providing thermal energy, and the heating plate structure 41 of the substrate preheating module 4 is electrically connected to the signal control module 1 and disposed on the substrate carrying module 2. Therefore, when the heating plate structure 41 is optionally configured to be used, the heating plate structure 41 can be allowed to be configured through the signal control module 1 to transmit the thermal energy provided by the heating plate structure 41 to the soldering materials S that is disposed between each chip C and the circuit substrate P, thereby preheating the soldering materials S at the predetermined preheating temperature. That is to say, before the chip bonding module 5 is configured to instantaneously heat the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature (before proceeding with the heating step for the soldering materials S), the substrate preheating module 4 can be configured to preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature, so that the circuit substrate P and the soldering materials S can be gradually heated from a room temperature (such as 25° C.) to the predetermined preheating temperature (for example, the temperature of the soldering material S is raised from room temperature to a preheating temperature of any positive integer between 50° C. and 200° C., or a preheating temperature of any positive integer less than 50° C., or a preheating temperature of any positive integer greater than 200° C.). However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.


More particularly, referring to FIG. 1, FIG. 3 and FIG. 4, the chip bonding module 5 is electrically connected to the signal control module 1 and configured to correspond to the substrate carrying module 2. For example, when the chip bonding module 5 is optionally configured to be used, the chip bonding module 5 can be allowed to be configured through the signal control module 1 to instantaneously heat the soldering materials S that is disposed between each chip C and the circuit substrate P at a predetermined heating temperature (or a specific heating temperature). In one of the feasible embodiment, the chip bonding module 5 includes a laser heater 51 (such as a laser diode or any kind of laser generator configured for providing a luminescence wavelength or a luminescence band that can be adjusted or replaced according to different requirements) for providing a laser heating beam L1, and the laser heater 51 of the chip bonding module 5 is electrically connected to the signal control module 1 and movably or fixedly disposed above the substrate carrying module 2. Therefore, when the laser heater 51 is optionally configured to be used, the laser heater 51 can be allowed to be configured through the signal control module 1 to project the laser heating beam L1 generated by the laser heater 51 onto the soldering materials S that is disposed between each chip C and the circuit substrate P, thereby instantaneously heating the soldering materials S at the predetermined heating temperature. That is to say, when the chip bonding module 5 is configured to instantaneously heat the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature (during the heating step for the soldering materials S), the substrate preheating module 4 can be configured to continuously preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature, so that the circuit substrate P and the soldering materials S can be instantaneously heated from the predetermined preheating temperature to the predetermined heating temperature (for example, under the condition that the predetermined heating temperature is greater than the predetermined preheating temperature, the temperature of the soldering material S is raised from the predetermined preheating temperature to a heating temperature of any positive integer between 200° C. and 300° C., or a heating temperature of any positive integer less than 200° C., or a heating temperature of any positive integer greater than 200° C.). That is to say, during the heating step for the soldering materials S, the circuit substrate P and the soldering materials S will not be instantaneously heated directly from room temperature to the predetermined heating temperature, thereby avoiding residual thermal stress in the soldering area due to instantaneous thermal expansion and contraction. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.


More particularly, referring to FIG. 1, FIG. 4 and FIG. 5, after the chip bonding module 5 is configured to instantaneously heat the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature (after completing the heating step for the soldering materials S), the substrate preheating module 4 can be configured to continuously preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature (so as to keep the temperature constant, or keep the temperature constant) to prevent the circuit substrate P and the soldering materials S from being instantaneously cooled down from the predetermined heating temperature to the room temperature (or to avoid residual thermal stress in the soldering area due to instantaneous thermal expansion and contraction), thereby increasing the connection strength or bonding strength between the soldering material S and the chip C, and increasing the connection strength or bonding strength between the soldering material S and the circuit board P.


It should be noted that referring to FIG. 1 to FIG. 7, the first embodiment of the present disclosure further includes a chip transferring and bonding method, which includes: firstly, referring to FIG. 2 and FIG. 7, carrying a circuit substrate P by a substrate carrying module 2 (step S100), and then transferring a plurality of chips C to the circuit substrate P by a chip transferring module 3 (step S102); next, referring to FIG. 3 and FIG. 7, preheating the circuit substrate P at a predetermined preheating temperature by a substrate preheating module 4 (step S104), thereby allowing a plurality of soldering materials S that is disposed between each chip C and the circuit substrate P to be preheated at the predetermined preheating temperature that is provided by the substrate preheating module 4; then, referring to FIG. 4 and FIG. 7, during the step of preheating the circuit substrate P at the predetermined preheating temperature by the substrate preheating module 4 (that is to say, the circuit substrate P and the soldering materials S can be maintained in a constant temperature state), instantaneously heating the soldering materials S that is disposed between each chip C and the circuit substrate P at a predetermined heating temperature by a chip bonding module 5 (step S106); afterward, referring to FIG. 5 and FIG. 7, continuously preheating (or keep warm) the circuit substrate P and the plurality of soldering materials S at the predetermined preheating temperature (or continuously maintaining the temperature of the circuit substrate P and the soldering materials S at the predetermined preheating temperature) by the substrate preheating module 4 (step S108), so as to prevent the circuit substrate P and the soldering materials S from being instantaneously cooled down from the predetermined heating temperature to the room temperature (or to avoid residual thermal stress in the soldering area due to instantaneous thermal expansion and contraction); next, referring to FIG. 6 and FIG. 7, removing a temporary carrying substrate T by the chip transferring module 3 (step S110).


It should be noted that as shown in FIG. 3, before the step S106 of instantaneously heating the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature by the chip bonding module 5, the substrate preheating module 4 can be configured to preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature, so that the circuit substrate P and the soldering materials S can be gradually heated from a room temperature to the predetermined preheating temperature, thereby avoiding residual thermal stress in the soldering area due to instantaneous thermal expansion and contraction.


It should be noted that as shown in FIG. 4, in the step S106 of instantaneously heating the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature by the chip bonding module 5, the substrate preheating module 4 can be configured to continuously preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature, so that the circuit substrate P and the soldering materials S can be instantaneously heated from the predetermined preheating temperature to the predetermined heating temperature, thereby avoiding residual thermal stress in the soldering area due to instantaneous thermal expansion (or avoiding thermal stress in the soldering area between the soldering material S and the chip C, and in the soldering area between the soldering material S and the circuit substrate P).


It should be noted that as shown in FIG. 4 and FIG. 5, after the step S106 of instantaneously heating the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature by the chip bonding module 5, the substrate preheating module 4 can be configured to continuously preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature to prevent the circuit substrate P and the soldering materials S from being instantaneously cooled down from the predetermined heating temperature to the room temperature (or to avoid residual thermal stress in the soldering area due to instantaneous thermal contraction), thereby increasing the connection strength or bonding strength between the soldering material S and the chip C, and increasing the connection strength or bonding strength between the soldering material S and the circuit board P.

For example, as shown in FIG. 8, when the laser preheater 42 is optionally configured to be used, the laser preheater 42 can be allowed to be configured through the signal control module 1 to project the laser preheating beam L2 generated by the laser preheater 42 onto the soldering materials S that is disposed between each chip C and the circuit substrate P, thereby preheating the soldering materials S at the predetermined preheating temperature. It should be noted that when the chip bonding module 5 (or the laser heater 51) is configured to instantaneously heat the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature (during the heating step for the soldering materials S), the substrate preheating module 4 (or the laser preheater 42) can be configured to continuously preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature, so that the circuit substrate P and the soldering materials S can be instantaneously heated from the predetermined preheating temperature to the predetermined heating temperature (or the circuit substrate P and the soldering materials S will not be instantaneously heated directly from room temperature to the predetermined heating temperature), thereby avoiding residual thermal stress in the soldering area due to instantaneous thermal expansion.

For example, as shown in FIG. 9, when the micro heaters 52 are optionally configured to be used, the micro heaters 52 can be allowed to be configured through the signal control module 1 to transmit the thermal energy provided by the micro heaters 52 to the soldering materials S that is disposed between each chip C and the circuit substrate P, thereby instantaneously heating the soldering materials S at the predetermined heating temperature. It should be noted that when the chip bonding module 5 (or the micro heaters 52) is configured to instantaneously heat the soldering materials S that is disposed between each chip C and the circuit substrate P at the predetermined heating temperature (during the heating step for the soldering materials S), the substrate preheating module 4 (or the heating plate structure 41) can be configured to continuously preheat the circuit substrate P and the soldering materials S at the predetermined preheating temperature, so that the circuit substrate P and the soldering materials S can be instantaneously heated from the predetermined preheating temperature to the predetermined heating temperature (or the circuit substrate P and the soldering materials S will not be instantaneously heated directly from room temperature to the predetermined heating temperature), thereby avoiding residual thermal stress in the soldering area due to instantaneous thermal expansion.
