Hi Sergey, Do you know the Moisture Sensitivity Level of the component ? This is normally recorded on the DRY PACK that the device comes in. It is not unusual for a device to POP CORN and still work in test. It depends how much damage there is to th

Hello all, does any body place PoP parts? We are running them through a regular process(paste place reflow) and we don't have good rates on these. Mostly we observe opens at the sides of the part. We are thinking to purchase a flux feeder, but I wan

I have gold fingers that I want to mask when running over the wave without pallets. They're on the leading edge of the board. I recall seeing rubber boots that slid onto the fingers to mask them. Pop 'em on before the wave; pop' em off after and r

If you have a board that you've run several times, now you run it and like before all settings are the same, but now you have 0603's randomly skewed or an inch or so away from their intended pad (as if popped up in the air), or an occasional 7343 cap

Hello, Recently I have change our profiles. After I profile one board it look really good, within the paste spec. But I have noticed when board leaves the reflow zone and enters the cooling zone it looks like popcorn effect some components jumping o
