Hey Jack: What is it with you and the IPC?? ;-) Can use the IPC documents that the IEC "xeroxed" and republished? ;-) Consider: � Vern Solberg is teaching a two day course titled "Printed Circuit Board Design For Surface Mount Technology" at Uni

In my experience, the most commonly accepted theory is that 100% inspection is only 80% effective AT BEST. That means that if your inspoectors are happy, noy outside concerns, well-rested, etc, they will catch 80% of the defects. This number goes d
