Bridging Causes: * Insufficient flux * Excessive pre-heat * High conveyor speed * Solder contamination

Well I finally got the power turned back on at my house. Guess they only let ya slide so long without paying the bill. I still say 4 months is OK - especially inthe winter time. But requardless, wave soldering 0402s is nuts. Getting adhsive to fi

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

hello guys ; we are using some standard selective wave soldering unit used in lined ; the drawback of a such machine is 1/the speed which is quiet low (the board is coming on position through the conveyor, then the head delivering the solder moves s

Anyone with selective wave experience ? I'm buying the Selective Wave machine and trying to workout the comparison matrix. Can someone tell me what criteria should I look at when listing down the matrix ?...things like, min clearance to the high prof

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f

Hi I have been struggling with boards for high quality picky customer. I am getting flux waves (like splashed - too hard to clean) after wave, where as we are still using Kester 979 (No clean flux, but as we are getting visible marks which looks si

With DIP type components, a sub-par fluxing method (foaming a no-clean), and a chip wave where one is not needed are formulas for bridging and insufficient wetting. If you have SMD's on the wave solder side of the board greater than 0603, and no SOT

Hello everyone, I have a question regarding wavesoldering and measuring if a proces/machine is in control. I made a custom carrier for measuring contact time, parallelism, solder temperature, coveyorspeed and some data of the preheat section. The s
