I have a small board with two through hole and two SMTs. Is it easier to manufacture with the SMTs on the top or bottom? Thanks, John

I have been trying to tell people at work that minor scratches on solder resist on BGA will not effect functionality of BGA, instead they want to attempt repair of these scratches. Any suggestions.

Some no-cleans will pool flux on the top of the solder joint which acts like an insulator. I normally do not paste "contact" pads. You can have your board house HASL them if you need the extra bump on the pad.

Well that is completly unacceptable for me and im sure 99% of mfgrs. I have seen people use extruded aluminum tubes. They any good? Know anyone who sells em? Thanks

How many times can you safely run a board across the wave solder? We have an unwritten rule here saying that twice is all that we can do. But it has been an unwritten rule for so long that no one knows where it orginated. Thanks for your imput.

Well, there you have it Pavel, Tim says to switch to DEK. Start packing up your MPM.

At the risk of being lambasted the Contact machines are very easy to program and have double the feeder capacity in a much smaller footprint. Please don't hate me.

hello, I would consider essemtec machines visit http://www.essemtec.com, thay are extremly flexible and have lot of tracability features. with cleanroom and smt machines this is very tricky. I would separate smt from cleanroom. mark
