Hi, are you dealing with Leaded or Lead Free P-BGA ? soldering by Lead or Lead Free paste ? Any way, some time, bridges can be caused by moisture entrapped in the BGA body. Make sure if is respected the correct MSL's allowed flore exposure time, ot

We are in a position where we have to purchase Leadfree BGA's and have them re-balled as leaded. I'm looking for some data from anyone who has done large volume outsource. 1) What percent fallout should I expcet from the re-balling process. 2) After

We are going to start doing rework of Lead Free BGA's. Have always used flux for SN/Pb boards/BGA's with good results. Can flux be used fro lead free as well? Boards were originally assembled using lead free paste and components. Hence, the BGA w

Hi, Does anyone know what the placement success percentage is for lead components And the placement success percentage for lead free BGA components. We place many varieties of BGA devices, over 100 different size parts, from 1000 pin BGA to small 4mm

Many high rel assemblers reball their LF BGA with SnPb balls. In other less demanding environments, SnPb paste with LF BGA produces acceptable reliability.

RoHS BGA. No lead in it.
