The method of tin connection occur during Rigid flex PCB assembly
The method of tin connection occur during Rigid flex PCB assembly:
1. Design according to the PCB design specification. The long axes of the two end chips are perpendicular to the welding direction, and the long axes of the SOT and SOP should be parallel to the welding direction. Widen the pad of the last pin after the SOP (design a tin stealing pad).
2. The pins of the plug-in components should be formed according to the hole spacing and assembly requirements of the printed board. If the short-insertion welding process is used, the component pins on the welding surface are exposed to the surface of the printed board by 0.8~3mm, and the component body is required to be inserted. correct.

3. Set the preheating temperature according to the size of the PCB, whether it is a multi-layer board, how many components there are, and whether there are mounted components.
4. The tin wave temperature is 250±5℃, and the soldering time is 3~5s. When the temperature is slightly lower, the speed of the conveyor belt should be adjusted slower.
5. Replace the flux.
