Description

Technical Field

[0001] The utility model relates to the technical field of PCB board welding, in particular to a welding jig for cables and PCB boards. Background Art

[0002] PCB is the abbreviation of Printcd Cicuils Board, which is a printed circuit board. PCB is made by printing technology and etching technology, and can be used to connect parts to each other and as a support for parts. PCB is mainly divided into three categories: single-sided board, double-sided board and multi-layer board.

[0003] Among them, double-sided PCB is a very important PCB. There are double-sided metal base PCB, Hi-Tg heavy copper foil PCB, flat winding double-sided PCB, high-frequency PCB, mixed dielectric base high-frequency double-sided PCB, etc. on the market. It is suitable for a wide range of high-tech industries such as telecommunications, power supply, computer, industrial control, digital products, scientific and educational instruments, medical equipment, automobiles, aerospace defense, etc. The difference between double-sided PCB and single-sided PCB is that the circuit of single-sided PCB is only on one side of PCB, while the circuit of double-sided PCB can be on both sides of PCB, and the circuit of double-sided PCB is connected by vias in the middle.

[0004] The manual soldering methods of double-sided PCB circuit boards are mainly divided into manual soldering and machine soldering. For small-batch production, manual soldering is an economical choice, although it requires more patience and skills. During the manual soldering process, when soldering double-sided PCB circuit boards, since the circuits on both sides need to be soldered frequently, the PCB board needs to be turned over many times. The conventional methods of fixing double-sided PCB boards, such as screw fixing method, soldering fixing method, crimping fixing method, plug-in fixing method and adhesive fixing method, are applicable to different situations. However, after fixing the double-sided PCB board, it is not convenient to turn the PCB board over and then solder the circuits on the other side. Utility Model Content
