In almost every application an ultrasonic spray fluxer will out perform foam fluxing. Better soldering results are what most expereince after making the change to U/S spray. There are good ultrasonic units from USI and Sono-Tek. www.ultraspray.com w

CK, If the contact length with the wave is decreasing when decreasing the conveyer speed and visa versa you need to check the machines electrical or electronics something is very wrong. Contact length is determent by wave design, wave height, convey

I think machine selection depends upon your application (pitch, volume, changeover from pb to pb free etc...) I have experience with ERSA and Pillarhouse Jades. Both very good in their own right. Pillarhouse are relatively cheap, and quick to chan

Jim, In a previous life, we built some flex circuits for a customer. The configuration was a flex cable, with a circuit at one end of it. We had fixtures made out of the same material that we had selective wave solder fixtures made from. Cut an i

Tim, I cannot remember what model our T.D. wave was it was a small unit about 8 ft. long "tabletop" is what I call them. In keeping up with this thread I noticed a lot of T.D. support. So, I decided to backtrack and review history with my previous pe

The question is are you talking of a reflow or wavesolder process. If your talking reflow I used to use a stepped stencil to ensure I had sufficient paste and then make a double pass with my squeegees. First pass with a 45 degree rubber squeegee to f

| We've recently encountered this problem where one of our .050" pitch BGA's were reflowing at the wave thus causing shorts... The board was profiled with probes stuck to a QFP solder joint, an 0603, and one of the BGA joints. There was an almost 7
