Is there an industry standard in calculating SMT process PPM level for benchmarking purpose ? What are the industry benchmark ppm number for some of the defects like solder short for 20-mil QFP, tomstone problem for 0603 components etc....

So we have 3 new ITW/EAE Centurion ovens that all have issues when running nitrogen to keep the o2 ppm below 1000. It is always much higher, sometimes gets lower when no boards are loading in. They've had us replace valves and do an upgrade kit that

Hi Mike, How do we measure the O2 ppm in N2 environment. I don't understand why the customer keep insisting me to use N2 instead of Air. I don't see the need for it as I done have any soldering issue. Can you share with me why N2 is needed at the fi
