Correct preheat and reflow secondary cooling when there are many benefits of PCB assembly, you need a simple procedure in these two repair technicians work. In fact, the warm-up PCB, the technician can do other preparatory work, such as PCB, solder paste and flux coating.
Of course, the need to address the new components of PCB rework process, because it has yet to test the circuit, which is a real time savings. Obviously, do not have to be scrapped in PCB rework caused the cost savings of prevention is arrived was twelfth treatment.
Accordingly, the substrate can be reduced due to delamination, raw spots or air bubbles, warping, fading and premature curing and to eliminate excess waste. Proper use of warm-up and secondary cooling of the PCB assembly manufacturer the two most simple and most necessary rework process.
