We use Wondermask 2211 and we haven't had issues with the material creating gunk in the pot. You might want to call TechSpray and consult with a product specialist who can better advise you on what's best for your application. Rob mentioned the wave

does it only do this with one assembly or panel config? i have seen this when the sensor shoots through a hole in the pcb/panel. the machine sees the panel come in, but it either overshoots or moves slightly into the open area. if i remember correctl

Not a problem, it forced me to put on my big boy pants and figure it out for myself. I felt pretty dumb when I realized what I had missed. If you have any custom procedures made up for maintaining the solder pumps and pot that would be great. I'm n

In a previous lifetime, we had a selective solder machine where I would see solder splashes in the roof of it. I thought someone might have been putting the solder extremely high. But when it was melting there would be bubbles that burst. The manufac

I have found Superior No. 75 to be an absolute miracle worker when it comes to nozzle maintenance. I let our worst nozzles soak in that over the weekend and then the majority of the dross would literally flake off with light pressure from a pick/scre

Hey guys, I ran a couple of profile in our wave solder machine using wave optimizer and this is what i got: Parallelism = 0.0 Immersion Depth = 2.1mm to 2.4mm with varying immersion time from 1.1 sec to 3.1 secs. Contact Length = between 5.0 to 6.0

| 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

| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre

| | | All y'll: I could use your input on determining when to skim dross from a wave solder pot. | | | | | | On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. O

| Does anyone out there have any pictures (jpeg preferred) of solder paste prints - or know where some are available. It will be awhile before our 35mm camera for our 3D scope arrives and I need some for inspection criteria. I need the good, bad, and
