Not all but some new boards we have had solder joint problems, for example some of the pads refuse to solder at all and the solder paste ends up attched only to the leg, reworking makes no difference and a variety of fluxes have failed. How can some

We built some boards with incorrect Bgas and we had to pull the bad ones off. I need to know if we need to bake the boards before we add the correct BGAs on and resend through the reflow? We need to get these boards shipped asap after we install th

We just installed 2 YESTech 2050's for our 2 lines and I'm extremely happy with them. Our machines are setup inline post reflow w/ the capability of diverting good/bad boards utilizing Nutek's t-type turn unit. Of course, we all know that the objec

I know this is not SMT related but would anyone care to comment on Alpha 856 flux, good/bad experiences or any known issues? I did some samples recently using it and had excellent results. Information on it seems a little hard to find and it makes

Dude: First, go to the input/output screen and make sure they fire manually, just to be sure they're functional. One other thing to look for is, make sure those magnetic sensors on the doors are perfectly lined up with the ones on the mach

Does anyone know if there is any kind of industry standard for x-out pcb's coming from board houses. I have been seeing more and more pallets/panels coming from various board houses with alot of bad pcbs. I have been in the industry for a little over

Not aware of any published standard for this. Usually we take care of this upfront with the supplier. No more than X amount of panels with one or more Xouts in any lot, No more than X number of Xouts per panel, so on and so on. Not defending boa

Anybody ever use SAM to inspect a bare pcb? What can you see? Is the scatter noise so bad you can't even see the copper layers? I would think you could at least see to some depth and then flip the board over. I work in a R&D environment so speed

I've never had this problem on an Omniflo oven, but have seen it on others. It has always turned out to be mechanical. A bearing going bad or FOD in the rails. I would pull the chains and carefully check each link of both chains, all of the bearin
