Dear fellow process engineers, Some solder joints "trough hole component" have cracked. I suspect that in the market some technician tryed to straighten some components (LED) and has applied enough force to actually brake the joint. The joints were

I'm working on a protobuild for a pcba. THis pcba uses double-reflow, paste-in-hole process. On bottom side there is a Ceramic BGA, size 35 X 35 mm, thickness 6mm, over 900 balls count (ball pitch 1mm)and it weighs a hefty 20 grams. Printing uses 6 m

Hey Kyle - Good for you for pushing your horizons and considering pin-in-paste (aka "Intrusive Soldering"). Don't let the nay-sayers out there discourage you. When I encounter mixed tech PCBAs (SMT and through-hole) my first choice, if the design a
