After the SMT patch proofing of the SMT small batch patch processing factory is completed, some follow-up processing procedures, such as testing, assembly, etc., are required. After all the electronic processing links are completed, it is delivered to the customer. The circuit board processed by the SMT patch It is relatively easy to be disturbed…
Hot air leveling is to immerse the printed circuit board in molten solder, and then use hot air to blow off the excess solder on the surface and metallized holes to obtain a smooth, uniform and bright solder coating, which has good solderability. The coating is completely free from exposed copper. The exposed copper on…
