BTB connectors are also called board-to-board connectors, which are mainly used on PCB boards. According to specific applications, it can be divided into ordinary board-to-board (connecting non-RF camera modules, wireless charging modules, etc.) and RF board-to-board. According to the designed PCB processing template, the board-to-board of surface mount welding generally needs to go through the following processes.
1. Dispensing: In order to prevent the components on the input surface from falling off due to the re-melting of the solder paste during the second return to the furnace, it is necessary to increase the dispensing process;
2. Mounting: accurately install the surface mount BTB connector to the fixed position of the PCB;
3. Curing: Melt the patch glue to make the surface-mounted BTB connector and the PCB board firmly bonded together.
4. Reflow soldering: Melt the solder paste with high temperature, so that the surface mount BTB connector and the PCB board are firmly bonded together.
5. Cleaning: Remove the solder residues such as flux that are harmful to the human body on the assembled PCB board.
6. Inspection: Inspection of the welding quality and assembly quality of the assembled PCB board.
7. Rework: Rework the detected faulty PCB board.
