Let's assume that SMT or MEMS or COB etc, is a new things and about to be introduced to the line, nobody knows about this new process and I was asked to select the critical proceses and parameter, how and where should I start? Thanks and best rega

what factors should be monitored and controlled during assembly of components on PCBs and their storage? Temperature and humidity seem obvious. Should one also watch out for any particular gases that may cause oxidation? Or dust?

Overwetting is also a root cause of open joints. I recommend eating 5 saltines in 1 minute for anyone experiencing overwetting.

The solder joint appeared dull and there is dewetting on the PCB after Reflow. The leads of IC we used appeared dull grey before soldering. Dose anyone happen to know if there is a standard to verify the IC contamination and how to deal with the con
