What aspects should be paid attention to in the reflow soldering process?

1. Set a reasonable reflow soldering temperature curve and do real-time testing of the temperature curve regularly.
2. Weld according to the welding direction of PCB design.
3. Strictly prevent the conveyor belt from vibrating during the welding process.
4. The welding effect of a printed board must be checked.
5. Whether the welding is sufficient, whether the surface of the solder joint is smooth, whether the shape of the solder joint is half-moon, the situation of tin balls and residues, the situation of continuous welding and virtual welding.
6. Check the color change of the PCB surface, and adjust the temperature curve according to the inspection results…
