Hi, Has anyone got first hand experience with the JT wave soldering machines, WS series? I use a low solid VOC free flux and it seems I have problems atomizing the flux properly and this generates soldering defects, leaving lumps and big solder bal

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

Yes, I have tested some boards, and found that most QFPs which near the via will have the higher temperature. One of my customer requirement is to have the temp less than 200 deg C for top side. We were using the hi temp wire to solder the QFP's for

Hello everybody, I had not noticed until yesterday this situation. Whenever the wave operator has a problem with a PCB (i.e. lifted parts, misprayed flux, etc.) they wave solder the PCB again "to fix it". The problem is that PCBs do not look pretty

Dave, We're reworking with flux and solder. We're observing "exploding" joints, as well...as though something is trapped in the joints (either excess flux not burning off during solder, or residual moisture). As mentioned above, I spoke with the f

I have problems with blowholes during the wave soldering process. I already find out that the stock time between reflow and wave is the most important. The longer the boards are in stock the more blowholes we have. We don't have a climat controlled

KRIKIES! If that wasn't a sales pitch, I don't know whut was, me lad. Optimizer is good for DoE's and process characterization, but no substitute for the artform that is wave soldering. When me lads here in Purchasing get PCB's from all over the w

We just got new boards in that have ENIG pads. In the past we had a problem with too much gold getting into the wave solder pot from large connectors getting tinned at the wave. Do we have to worry about too much gold getting into the pot with this

Patrick...I'll give you a couple of examples. Wave Soldering, the Science: you're getting solder shorts and you slow your belt speed down just a bit knowing that this effectively lowers your contact length and improves your peel-back for that tou
