Description

Technical Field

[0001] The utility model relates to the technical field of ceramic substrate pin insertion, in particular to a ceramic substrate pin insertion fixture. Background Art

[0002] Ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface of alumina or aluminum nitride ceramic substrate at high temperature. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft solderability and high adhesion strength, and can be etched with various patterns like PCB boards. The ceramic substrate can also be soldered to connect multiple pins and pins like PCB boards.

[0003] When the existing pins and ceramic substrates are soldered, the staff is required to manually connect each pin to the ceramic substrate one by one. This connection method is not only inefficient, but also causes the soldering connection between the pins and the ceramic substrate to be skewed, ultimately rendering the entire ceramic substrate unusable and reducing its yield rate. Therefore, in order to solve the above problems, we propose a pin fixture for ceramic substrates. Utility Model Content

[0026] By fixing two limit columns 3 on the four directions of the upper end surface of the base plate 1, the base plate 2 is inserted into the eight limit columns 3. When in use, the base plate 2 is first placed between the eight limit columns 3, and the limit columns 3 limit the overall base plate 2. A substrate limit frame 4 is provided at the upper end of the base plate 2, wherein a plurality of protrusions 9 are arranged and fixedly connected on the front and rear sides of the upper end of the substrate limit frame 4. The provision of the protrusions 9 not only limits the overall substrate limit frame 4 on the base plate 1, but also limits the ceramic substrate placed in the substrate limit frame 4.

[0027] A plurality of short pin holes 506 are provided through the pin limit frame 501, and the short pin holes 506 and the long pin holes 508 inside the pin block 503 are arranged one by one.

Slots 10 are provided at the four end corners of the upper end of the base plate 1, and the four end corners of the lower end of the pin limit frame 501 are fixedly connected with the insertion column A502, and the insertion column A502 is inserted and matched with the slot 10 on the base plate 1;

Compared with the existing method of welding the pins 8 to the ceramic substrate one by one, the above setting and operation are compared with the existing method of welding the pins 8 to the ceramic substrate one by one. The plurality of pins 8 contact the ceramic substrate at the same time through the movement of the movable plate 504.

After the soldering furnace is heated, the entire device is taken out of the soldering furnace, and the base plate 2 is configured as a mesh structure, which enables the base plate 2 itself to have a ventilation and cooling function.
