While underfilling BGA "mounted" on blacked pad boards could improve the reliability by attaching the BGA to the board, you should believe that all components soldered to the board will be affected by the black pad, not only BGA.

Is anyone aware of any standard for bare board laminate for lead free assembly? We have been using IS410 with good results but not sure if maybe it is overkill and not worth the price premium? What is everyone else using?

Anyone know of a clean effective way to remove silkscreening from SMT components? We are currently using a laser source removal process and wish to consider alternatives.

Team Services: Removing IC markings * methylene chloride to remove the markings * xylene and toulene will also remove some paints * "Black boxing" Simply use a tiny piece of sandpaper to "scratch the surface" and render the device blank. Chris: Sand

You're not that late. Every time we've been involved in part marking removal, it was done to make it difficult to pirate a board design.

Dave F was right on the application, it has worked so far (3 years). Thanks for the ideas so far.

Anybody doing their own BGA Reballing? I'm looking for a good kit that can handle both leaded and lead-free. Any suggestions?

You are correct, the Hover Davis label feeder works on 'un-punched' flat carrier. Get a sample of your dots on the tape and send it to Hover Davis to see if their feeder will work for you. The Hover Davis feeder will peel the dot off of the tape so

Yep, we either use kapton tape or mask now depending on the application. It would be nice to be able to do it on a machine but the Hover-Davis label feeders are very expensive. May not be worth the cost for the volumes we run.

Hi, Cool, and that would be a fantastic idea to do it in the SMT phase with a machine, and much faster. Your right about the feeder costs, and I guess you might be able to pick up something second hand? Regards, Grant
