While investigating a routing study for a new bga device, I found the vendor used round 20 mil pads on 0402 decoupling caps.This allows fitting the caps between break out vias on their 1mm pitch BGA. Round pad gives about 8 mils diagonally from pin t

Have experienced this on a few different cap. parts. Agree with other postings. Following are solutions to problems we have had: 1) Cracked cap too close to board edge per IPC spec. Designer replaced part with 3 caps in series to eleviate stress

We are a small/medium contract manufacturer and like most we do our best to ensure that PCB's we process are panelised to ensure efficient throughput and good quality results. Sometimes however we are stuck with free issue PCB panels supplied by som

Well it depends on what kind of oven you have. If you have a short oven, you are going to have a difficult time. You will probably end up having several different profiles if that is the case. We have 3 BTU TRS 212 furnaces. They are fairly long 8 zo
