I don't know if it's legal, but I do know that other companies are doing the same thing. I have a couple of semi-auto printers that I actually sold my current company from my last company. Called 'em up a few months ago to order some parts and they w

You can say: The pad was lifted after reflow and prior to the dye and pry failure analysis. When we see lifted pads, we think: * That's a good solder connection * Either it took a lot of force to lift that pad or the fabrication of the board in the

Hi all, We had similar problems a while back. Boards would fail at test but if you applied pressure to the BGA they would pass. Turned out that during the PTH assembly process the Operators were flexing the cards during the insertion of an Oupin C

Hey Bwelch, We use the Marantz Nspec 22x (similar to the DL-14) table top AOI here and it's great. No need to bolt it down or attach it to a heavy table; the g-forces are extremely minimal and the machine still operates quickly. 1 guy can pick up t

Well, when facts and data become "complaining' and "scare-tactics", it's pointless to carry on a conversation. You might as well twist tin whiskers so that it becomes a GOOD thing. "Just say YES and we'll move on!" http://www.funnyordie.com/vide

Thanks to Scott for your reply, much appreciated. Are you aware of any new developments in this area? Particularly in respect to the solvents? We are aware that fluorine chemistry is now in-use with amazingly high boiling points. We understand that

When switching from cleaning RMA to a no-clean flux, one area that is commonly overlooked is the stencil cleaning operation. Stencil cleaners that are effective in cleaning RMA often fail when cleaning no-clean (especially alcohol cleaners). Pallet
