Reflow Oven Zone Separation Challenges
Reflow Oven Zone Separation Challenges
We recently purchased an oven profiler. Some of the zones are competing with each other to get to the correct temperature. How do I find prevent the oven from having competing zones while getting an accurate process?

PCBA Inspection Concerns
PCBA Inspection Concerns
We inspect PCBAs on a relatively hard ESD mat. Will moving the PCBs on the mat will scratch and stress the soldered components on the bottom side?
