First of all, we must understand what the virtual soldering of a PCB board is. Virtual soldering in SMT is a relatively common problem in chip processing. Virtual welding is the appearance of welding together, the surface is welded but in fact, it is not completely fused together. The reason for the virtual welding is…
In the SMT patch proofing process of the SMT small-batch patch processing plant, a white spot or white spots in Circuit Board will appear on some circuit boards. What is going on? The appearance inspection also accounts for a large part of the quality inspection of electronic processing. The circuit board with white spots is…
In SMT patch proofing, some orders require only a small number of orders, such as one or two pieces or two or three pieces, and do not need to be sampled on the machine. This may be an SMT patch-proofing processing method of manual placement. IC is the English abbreviation of Integrated Circuit (Integrated Circuit)….
