First, your primary side component pads should be designed according to SM-782A, "Surface Mount design & Land Pattern Standard". Next if you did that and your secondary side component pads are the same size as your primary side components, your diff

I need help. I recently purchased a used Dynapace Wave Exit Conveyor, model # C17697, at auction. The conveyor arrived with no user manual. I need a password to program it and Dynapace is no longer in business. Does anyone know or can suggest a d

We are evaluating a low halide Water soldering flux (Aim WS716). Has anyone had good/bad experience with it? Our operator has mentioned strong and irrating smell, even when standing a foot away from the conveyor entry/exit. The fluxer is embedded w

My company just purchased a Vecta (E-vert) wave soldering machine. Bridging has become a serious issue, both on SMT components and thru hole. We are currently seeing about 500 ppm. The products that are being run now were run previously on our old

John - CK can probably help you further once you answer those questions, but for now what's your top side temp and how are you applying flux? Two of the primary causes for bridging are conveyor instability (vibration) and turbulance in the solder wa

DDave, I do not have the benefit of having the old machine here for comparison unfortunately. Comparing topside wetting to old sample boards run on the older machine show similar results. No solder balls. I have a thermal profiler and have run ma

Thanks for the acvice, Dave and John. Like I stated above, I didn't feel comfortable with changing wave parameters since I knew that we'd be compromising our wave quality. I'll try the peelable mask thing, reprofile, and let you guys know what i fo

Hello, We recently installed a new/used UPK 650 fitted with a foam fluxer using an RMA flux chemistry. We have had problems with icicling and bridging from the beginning. The bridging occurs mostly on DIPs and connectors. The icicling is on longer

Hello Loz, Blue residues on circuit boards can be caused by copper corrosion, component body deterioration, marking permanently, and adhesive break down. In this case, a more subtle mechanism appears to be possible. This is a no clean application

| Hi Ya'll... | it's a Soltec Prisma and the conveyer keeps jamming. What it's doing is up at the exit end where the drive motor is, the chain keeps wrapping itself around the drive sprocket and jamming...this is on the backside rail, the frontside
