Well, we are in fact doing a no-clean, multi-shift, very high volume, minimal changeover operation. We use up any paste long before it gets old. Because of the sheer volume any reduction in paste scrap for us is big money. We also are in a zero de

We are having issues with these parts tilting to one side during reflow. Of course when they are tilted, they have to be reworked because the shield won't fit on. Changing board design and part design is not an option.... I think there are 2 reasons

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

Was this a lead-free capable material that fits into IPC 4101/126 or /129, like an Isola 370HR? I would not be surprised because from the picture I think I can see resin underneath the lifted copper, which is an interlaminate separate. This is a
