Does anyone know a rough price estimate on a new nitrogen reflow oven that can achieve very low oxygen levels - around 10PPM. Compared to a similar standard nitrogen oven that would for example go down to 500 PPM, what is a rough price premium for a

Just wondering why you need to scuff the surface at all, as a decent glue should take to the PCB material anyway. However, it may be a customer requirement, so you have to do it. Have you thought about getting the PCB's made with a rough surface wh

This question is directed to anyone having eperience with Sn62Pb36Ag2 solder balls for BGA's. Have you seen anything like a rough, raisin-like surface texture after ball attach? If so, what did you do about it? Thanks!
