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.

Thanks guys. I'm always getting feedback from purchasing and design that we should just put this info on the spec sheet, but I've always argued that the vendors will either ignore it, or it will become a cost driver. Thanks John S.

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.

While it's common to use RO where TDS is sometimes very high, like Cali; it seems like the RO is killing your beds. What happens when you run without RO?

That's what I thought. The humidity req't would be a non-issue when you are able to bake at 125C. Can you share details on how you bake at 70C?

Dave, our facility does only military and aeorspace contracts, we still use only tin/lead solder and 186 Rosin Flux, so this info is just what I need. Thanks for your imput.

Cuculi is right. Electrum pays you to take paste,dross,towels gloves etc... Great service!

Good afternoon, Could you tell me if MPM AP25/HiE can be equipped with side clamping system (snuggers)? It would be great to know the price of such modification as well. Thanks in advance. BR, Pavel

I agree with John S., laser is definitely the way to go. More flexible and maintenance-free than applying printed labels. John S., are you using Yag or CO2? rgds AR
