Description

Technical Field

[0001] The present application relates to the technical field of welding jigs, and in particular to a jig for welding a CAN base to a motherboard of an electronic product. Background Art

[0002] Generally, soldered components are mounted on the front end of the SMT, meaning that the components and the blank board form an SMT semi-finished product. The CAN base is used to connect the light board and the main board, providing support and conduction. Both the main board and the light board need to be tested for functionality on the machine. If the CAN base, main board, and light board are soldered together during SMT, the machine's main board test fixture will interfere with the PCBA structure, making functional testing impossible. Consequently, the industry has gradually developed a new technical solution that postpones the soldering of the CAN base, allowing both the main board and the light board to undergo functional testing. After the functional test is complete, the light board is first connected to the CAN base, and then the main board and CAN base are soldered together. This also facilitates rework.

[0003] However, while this process adjustment effectively avoids structural interference and enables smooth functional testing, it also introduces new problems. The increase in production processes leads to a decrease in overall production efficiency. In addition, due to the precision requirements for the spacing between components in the PCBA, this places higher demands on the control of the spacing between the motherboard and the CAN base. How to achieve precise control of the spacing between the motherboard and the CAN base during the soldering process while maintaining or even improving production efficiency has become a technical challenge that technicians in this field urgently need to solve.

The length direction of the first positioning rods 13 is parallel to the length direction of the platform 12 and perpendicular to the end face of the platform 12 away from the base plate 1. The positions of the first positioning rods 13 corresponding to the same positioning slot 11 correspond to the positions of the positioning holes on the main board; when the main board is placed on the platform 12, the first positioning rods 13 are passed through the positioning holes on the main board to accurately position the main board.
