Sure those products and other competitors listed in the fine SMTnet Archives provide a uniform solder deposit, how do you suggest that Russ provide the proper amount of flux and heat to properly form his solder connection?

Why would there be a need for such a standard? And who would produce such a standard? Thoughts are: * Why not call the BIG dogs in contacting [ie, Solectron, Flextronics, SCI, etc.] and ask them for copies of their T&C documents and mash them toge

I have documentation from many companies on a hand lotion that passes all of the critical tests required in handling of PCB's. If you wish I could copy or have the manufacturer send this information your way. Steve

We are unable to pick it up because we don't have any landing area, but some guys said that we can add a plastic cap on it so it may help...I will check up..unless you can suggest me other thing Thank you

We do not use this product. [Not to say there is anything wrong with it.] Check Phil Zarrow�s site [www.itm-smt.com] for a good article on paste evaluation that was in �Circuits Assembly� a cuppla years ago.

Take a look at the BarTector system. It was designed initially as a verification system, but has expanded to included inventory tracking. http://www.bartector.com/

Maybe the issue is not a proper rework method. Your shorts on the corners are caused by too fast of a profile causing the corners of the BGA to get too hot, too fast, which made them curl, like tatter chips.

Yo, Hussman69, you are one scary dude... in fact you remind me of that catbert... as an add-on, "metcal" has a good semi-auto BGA rework system and their engineering support is strong. then again, our engineers shd be optimizing the production lin

'Flash' is too thin to bear the traffic of most wear surfaces like Jake is talking about. Follow-up with the fretting corrosion discussion over on the current [Jim Zanolli / Teka] OnBoard forum.

I meant to include this in the original message. One, the solder balls are on the circuit side of PCB. Two, some of the vias on both top and bottom are closed and some are not. Is this a process problem with the board house(s)?
