I am new to wave soldering. Any information is greatly welcomed. Here is the problem. After soldering the boards they have a film on the bottom of them and sometimes a white powder looking substance. I have tried decreasing the amount of flux on

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

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

I hacked machine to only spend nitrogen when solder pump is on, this made about 80% save when you count in frame change, fluxing and operator slacking

Your solder paste is talking to you, follow its message. Listen to the paste. Be at one with the paste. If you insist on ignoring the message of the paste, add more paste, if you just need to complete the last board or so, but you really should ju

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

Any lead free will eat a leaded designed wave soldering machine. But SN100c will eat it the slowest, our soldering tips used to only last 3 months with SAC305 when we changed to SN100c solder wire we are having around 9 months tip life. Our wave sol

SPC was a fad of the '80's and has been mis-used by the igonorant for decades now! Doing SPC on defects is a case in point. Hell I implemented wave SPC programs before eating breakfast at 2 previous companies, and they worked great..resulting in 25

Hi all, it has been a bit of a delay but I've finally had a chance to do some further investigation on this. First off, we spend some time to clean the solder bath using Kester Solder Saver and scooped out a lot of crap. We then added about 5kg of
