What would be the best method for attaching the balls, when doing BGA rework. I Found that by using the solder paste, it will give us better rework yield vs using the paste flux ? My data was collected from a very small experiment and hard to conclud

We are currently using an Air-Vac DRS24 hot air BGA/SMD rework unit. Most of our nozzles are designed to channel the exhaust away from nearby components. This and a minimum keepout of .100" has prevented any issues with secondary reflow of those co

Folk's, I'm looking for some helpful suggestions for reworking wave soldered bottomside components that have been glued. I'm not a fan of the twist and break approach and as some of them either have a double dot or a slot configuration this tend's t
