Hi Shrek - Not sure why you think adjusting dwell time and preheats is a sales pitch, but I do appreciate your candor. These are proven, widely used techniques for attacking, eliminating and preventing the recurrence of blowholes. Since it is so ea

Good day, can i seek an advice regarding wave soldering. Will it be advisable to reload the board two times to improve its barrel fill volume? If yes, what is the maximum number of times we can repeat wave soldering on the same board. If no, what

The standard machine is set from the factory at 7-9 degrees, 7 is the most standard, why are you considering the change? before doing any thing to the machine, first identify why? what type of defects are you seeing? I have found, depending on the t

I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

I agree with RealChunks. The application of any of these "wave solder process control tools" is dependant on how the shop is run. At some shops, PM is inconsistent and slacked off on. At other shops, there is no technical expertise at the operator

I recently had the same problems, solder bridges on every thing I made, different customers boards, etc. I wave with no-clean flux. As I sorted out problems (pin holes, blow holes, splatter, etc.) I found a lot of variable factors. I changed flux,

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

Good afternoon all, I have been trying to find a solution to a defect I just noticed. After stencil printing and smt part placement on the secondary side of my boards, I run them through a wave soldering system. All my components got soldered perfe
