Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board fixture technology, specifically a PCB board heat sink welding fixture with high yield. Background Technology
[0002] PCB board generally refers to circuit board. Circuit board names include ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board (copper etching technology), etc.
[0003] In conventional PCB board and heat sink soldering, the board and heat sink are usually soldered manually by hand. When soldering PCB boards by hand, the heat sink will be crooked without being fixed. During the soldering process, the hand must keep pressing down on the heat sink to solder, which affects the quality and efficiency. Long-term work will cause finger pain for operators and may also cause the heat sink to be inaccurately fixed and misaligned with the solder pads. Utility Model Content
