Well, we got the baking part right at least. I would think that would help to rule out the barrel cracks allowing moisture escape. Plating too thin makes sense to me. In any case, do you think barrel cracking would be observable on a bare PCB?

We are required by most of our customers to apply a serial # to the boards that we build. As the PC boards have been getting smaller and open areas on the board are getting scarce we have been forced into using smaller and smaller labels. I am lookin

Our profile tempatures in the owen is: Preheat 6 zoones 135,155,165,175,185,195. Peak 3 zoones 255,245,240. We do check our profiles with test probs and a "Surveier" temrature recorder every 3 month and we are within the paste supplyer recommendation

Hi, we are currently offering service assembly of the enclosures and electronics for our clients. Sometimes that includes gluing of the enclosures and for smaller quantities, we used 983A hand glue dispensers. Now we want to buy small automatic glue

SMTXTRA as SMTEXTRA in UK? Susan? I know for a fact they are solid as we and some peer companies are suppliers of them for machine parts, feeders; nozzles, and calibration Jigs, even though our major business is with mounters and ovens, but no busine

Hi, "glass wicking failure" we don't know what this is, but we suspect that the reflow process could very well be the root cause for some of our pcba with micro vias failure. Micro vias pcb we know to well (we don't like them at all). There are No p

Thanks Dave. Talked to a few people at APEX this week and if nothing else, had my frustration reduced some. Of course I made sure I talked to mfg. people and avoided the design guys like the plague. ;) I actually picked up a copy of 785 a while bac

Hi All.. I need your advice, when you send your boards to be analized by external lab, what kind of result would you expect from them? Do you expect them to find the root cause of the problem and give countermeasure of the problem? (this is what I e

there is an IPC standard for machine accuracy and repeatability. Here it is how it works. You have to place certain number of parts on a specially designed PCB(that allows placing variety of parts on big part of the machine work area). After that you
