[sdiy] PCB assembly house board failure rates?

[Dan Snazelle]

I have actually found a lot more problems (my runs are between 50-200 units per run) doing through hole boards. 

Catastrophic screwups on the part of the pcb assembly house happened to me on a few different thru hole runs and took a lot of time and money (as pcb houses seem to be good at denying or ignoring any blame)


Anyway, since switching to smt, my failure rates have been as high as ten units out of 200 and as LOW AS ZERO. Usually on the lower side.

Thanks


Also....it pays to find a place you trust!
