Referring to fig. 1 to 6, the soldering jig 100 for a thermoelectric cooler includes a first jig 1 and a second jig 2.
The first jig 1 has a first body 11 and two first press pieces 12.
The first body 11 has a plurality of positioning grooves 111 and two first steps 112. The plurality of positioning grooves 111 are in air communication with each other. Each of the positioning grooves 111 is opened only at the top, and each of the positioning grooves 111 is used to receive and position a corresponding one of the thermoelectric particles 200 to be welded. The two first steps 112 are located above the tops of the plurality of positioning grooves 111 and at both ends of the first body 11 in the left-right direction D1, and the two first steps 112 face each other. The pitch P1 between the bottom plane 112a of each first step 112 and the top surface of each positioning groove 111 is set to satisfy the requirement of the first metallization layer 500 in which the first solder layer 400, to which the first substrate 300 is soldered to each thermoelectric particle 200, and the plurality of thermoelectric particles 200 are electrically connected on one side of the plurality of thermoelectric particles 200 in the vertical direction D2.
Each first pressing block 12 is adapted to be positioned on and detachably fixed to the top of a corresponding first step 112. Each first pressing block 12 and the corresponding first step 112 form a first substrate limiting groove G. Each of the first substrate-defining grooves G extends in the front-rear direction D3, and the two first substrate-defining grooves G are configured to receive and define the first substrates 300 of the thermoelectric refrigerator to be welded in the left-right direction D1 and the up-down direction D2.
The second jig 2 has two second bodies 21, two second press pieces 22, and two connecting plates 23.
The two second bodies 21 are spaced apart from each other in the left-right direction D1 to form a receiving space S. The receiving space S is used for receiving and limiting the second substrate 600 to be welded of the thermoelectric refrigerator in the left-right direction D1. Each second body 21 has a second step 211. The two second steps 211 face each other in the left-right direction D1.
Each second pressing block 22 is adapted to be positioned on and detachably fixed to the top of the corresponding second step 211. Each second presser 22 and the corresponding second step 211 form one first substrate-restraining concave portion R, each first substrate-restraining concave portion R extending in the front-rear direction D3, and both first substrate-restraining concave portions R are used to house and restrain the first substrate 300, to which the plurality of thermoelectric particles 200 of the thermoelectric refrigerator are welded, in the left-right direction D1 and the up-down direction D2.
Each connection plate 23 is connected between the two second bodies 21 in the left-right direction D1, the top surfaces of the two connection plates 23 are not higher than the bottom surfaces 211a of the two second steps 211, and a pitch P2 between the bottom surfaces of the two connection plates 23 and the top surface of the receiving space S is set to satisfy the requirements of the second solder layer 700 to be soldered to each thermoelectric particle 200 and the second metallization layer 800 to electrically connect the plurality of thermoelectric particles 200 at the other side of the second substrate 600 in the up-down direction D2 of the plurality of thermoelectric particles 200. The two connection plates 23 serve to confine the plurality of thermoelectric particles 200, which have been soldered to the first substrate 300, from the front-rear direction D3.
In the soldering jig 100 for thermoelectric coolers of the present disclosure, the corresponding thermoelectric particles 200 are confined in the front-rear direction D3 and the left-right direction D1 by the positioning grooves 111 of the first jig 1, the first substrate 300 is confined in the left-right direction D1 and the up-down direction D2 by the two first substrate confining grooves G of the first jig 1, so that the first substrate 300 and the plurality of thermoelectric particles 200 are positioned relative to each other before soldering, wherein the first solder layer 400 may be previously disposed on the top surface of the corresponding thermoelectric particle 200 in the up-down direction D1 by, for example, coating before soldering, and the first metallization layer 500 may be previously disposed on the first substrate 300 by, for example, an adhesive or patterning process before soldering, whereby, during soldering of the first metallization layer 500 with the thermoelectric particle 200, even if the solder forming the first solder layer 400 is melted and expanded, since the first substrate 300 is restrained in the up-down direction D2, the reaction of the first substrate 300 to the melted and expanded solder together with the reaction of the bottom surface of the positioning groove 111 causes the thermoelectric particles 200 to be restrained in the up-down direction D2, meanwhile, since the positioning grooves 111 of the first jig 1 position the corresponding thermoelectric particles 200 in the front-rear direction D3 and the left-right direction D1, therefore, the thermoelectric particles 200 are restricted in three-dimensional directions during the soldering with the first metallization layer 500 and the integration with the first substrate 300, the thermoelectric particles 200 are not deflected and rotated, the thermoelectric particles 200 are not deflected, so that after the thermoelectric particles 200, the first solder layer 400, the first metallization layer 500 and the first substrate 300 are integrated by soldering, the thermoelectric particles 200 are precisely positioned, firmly welded, and the bottom surfaces can be uniformly maintained (the bottom surfaces are only required to be flush with the bottom surfaces of the plurality of positioning grooves 111), thereby improving the reliability of the thermoelectric particles 200.
In the welding jig 100 for thermoelectric coolers of the present disclosure, the positions of the two second limiting concave portions R in the left-right direction D1 are fixed by connecting the two connecting plates 23 between the two second bodies 21 in the left-right direction D1, the first substrate 300 to which the plurality of thermoelectric particles 200 have been welded is limited by the two second limiting concave portions R in the left-right direction D1 and the up-down direction D2, the second jig 2 is placed on a work platform when the second substrate 600 is soldered, the work platform supports the two second bodies 21 and the second substrate 600, whereby a plurality of thermoelectric particles 200 are confined in the up-down direction D2 based on the work stage and the first substrate 300 confined by the two second confining recesses R, the second solder layer 700 may be previously disposed on the bottom surface of the corresponding thermoelectric particle 200 in the up-down direction D1 by, for example, coating before soldering, and the second metallization layer 800 may be previously disposed on the second substrate 600 by, for example, adhesion or patterning before soldering, whereby, in the process of soldering the second metallization layer 800 to the thermoelectric particle 200, even if the solder forming the second solder layer 700 melts and expands, since the expansion of each thermoelectric particle 200 in the up-down direction D2 is restrained and the expansion of each thermoelectric particle 200 in the front-back direction D2 and the left-right direction D1 is restrained by the first metallization layer 500 and the first substrate 300 which have been integrated, therefore, the thermoelectric particles 200 are also restricted in three-dimensional directions during the process of being welded to the second metallization layer 800 and integrated with the second substrate 600, the thermoelectric particles 200 are not deflected and rotated, the thermoelectric particles 200 are not deflected, so that after the thermoelectric particles 200, the second solder layer 700, the second metallization layer 800 and the second substrate 600 are integrated by soldering, the thermoelectric particles 200 are precisely positioned and firmly welded, thereby improving the reliability of the thermoelectric particles 200.
In the example shown in fig. 1, the plurality of positioning grooves 111 are arranged in the front-rear direction D3 and the left-right direction D1, and the positioning grooves 111 arranged in the front-rear direction D3 communicate with each other in the front-rear direction D3. The positioning grooves 111 arranged in the front-rear direction D3 communicate with each other in the front-rear direction D3 for a desired gas (e.g., air or nitrogen) flow during soldering to facilitate the performance of reflow soldering. In an alternative embodiment, the plurality of positioning grooves 111 may be arranged only in a single direction (in the front-rear direction D3 or the left-right direction D1). For example, the positioning grooves 111 aligned in the front-rear direction D3 communicate with each other in the front-rear direction D3 through the wall constituting the front-rear direction D3 of the corresponding positioning groove 111 being lower than the wall in the left-right direction D1, as shown in fig. 1, or the positioning grooves 111 aligned in the front-rear direction D3 communicate with each other in the front-rear direction D3 through holes (not shown) opened in the wall constituting the front-rear direction D3 of the corresponding positioning groove 111.
In the example shown in fig. 1, the two first steps 112 are mirror images of each other. The design and manufacture of the two first bodies 11 is thereby simple.
As shown in fig. 1, each first substrate stopper groove G extends through in the front-rear direction D3. In an alternative embodiment, one or both ends of each first substrate restriction groove G in the front-rear direction D3 are closed, thereby increasing the restriction effect on the first substrate 300 in the front-rear direction D3.
In the figure, the housing space S penetrates in the front-rear direction D3. Alternatively, the housing space S may not be penetrated in the front-rear direction D3, i.e., the two second bodies 21 are formed with through holes closed at the bottom at the periphery.
Likewise, the two second steps 211 are mirror images of each other, whereby the design and manufacture of the two second bodies 21 is simple.
In fig. 1 and 2, each first substrate stopper recess R extends through in the front-rear direction D3. In an alternative embodiment, one or both ends of each first substrate stopper recess R in the front-rear direction D3 are closed, thereby increasing the stopper effect on the first substrate 300 in the front-rear direction D3.
As shown in fig. 1 and 2, one of the two second bodies 21 is L-shaped, and the other of the two second bodies 21 is straight-plate-shaped and has a recess 212 at the bottom that is recessed upward and exceeds the top surface of the receiving space S. The recess 212 and the corresponding second step 211 are mirror images of each other, whereby the straight-plate type second body 21 can be used upside down for arranging the second presser piece 22.
In an embodiment, referring to fig. 1, the first fixture 1 further includes a plurality of first screws 13, and the plurality of first screws 13 are used for detachably fixing each first pressing block 12 to the top of the corresponding first step 112. Similarly, the second fixture 2 further comprises a plurality of second screws 24, and the plurality of second screws 24 are used for detachably fixing each second pressing block 22 on the top of the corresponding second step 211.
Note that in the figure, the first heat conduction layer 900a is disposed on the first substrate 300, and the second heat conduction layer 900b is disposed on the second substrate 600, but the first heat conduction layer 900a and the second heat conduction layer 900b may be omitted as the case may be.
Note that in the figure, the plurality of thermoelectric particles 200 are labeled with the respective types, i.e., N-type and P-type.
The above detailed description is used to describe a number of exemplary embodiments, but is not intended to limit the disclosure to the explicitly disclosed combinations. Thus, unless otherwise specified, various features disclosed herein may be combined together to form multiple additional combinations that are not shown for the sake of brevity.
