did the boards get built by hand or via smt process (through reflow oven)? Someone asked earlier if some one touched up the adjacent joint. The answer to that question is yes. Look at how the solder tails off the smt pad away from that joint! I suspe

I'm curious who may be currently using Automated Mobile Robots (AMRs) or Automated Guided Vehicles (AGVs) in production. I've seen a few companies using them to transport SMT parts from the warehouse to the SMT Line. I'm wondering what others are doi

I do know for our case...it was not just SMT manufacturing. There were many variable: 1) Part purchasing- The larger CM's would get better $ and lead times than we could. in some case we would have to wait 4-6 months before delivery. Or we could buy

My customer just assembles it to the car. We want to use the silica gel to avoid moisture since the assembled part (clock) reach him via ship after 50 days. The electronic circuit board has no conformal coatings at present. We are working on that. Ou

Thank you for advice, But main concern how to detect the problems with BGA on SMT line, and how I can validate "good" or "bad" profile. PS: SPC said that process Cpk 2, temperature profile in the upper spec limit for TAL and peak temperature.
