Steve, You almost got yout Man Card revoked for stating: "determining the risks associated with simultaneously applying compressive and rotational forces to the end of the barrel". Luckily you bounced back with "chewing up the copper". Just pokin

I'm trying to design a costing matrix for raw cards so our designers can estimate the costs of their raw card designs, this will hopefully slow down their lust for technology and get them considering project budget costs. Does anyone know of where I

Can anyone tell me if there is a procedure for storing raw PCB's? We currently are seeing an issue with lead free boards with dewetting. We tracked it down to one or two datecodes, but not all of the boards have dewetting. Is there a expiration da

Thanks everyone. I have thought about the moisture in the paste a lot, but never really gave the raw card moisture any consideration. The next time we run an assembly with the issue I will try baking some of the cards once the issue shows up to see i

Hi lads long time no post... I have an issue with a PCB, its a PCI card that we manufacture for a customer of ours. The customer is seeing a problem with contact on a PCI card with the motherboard, the PCI card is removed from the board wiped and th

TK, Hope you got it right only for this round of assemblies. Well, passing through a Reflow belt is not an ultimate process to dry circuit cards & take out moisture from Solder finished layers. First of all, if the packs were not unsealed (even s

You're correct, it does not matter on dual dots because they should be the same size. My concern is given that the FUJI will not see dual dots as a single item, in order to verify both dots I would have to program as them as seperate fids in which ca
