Anyone who uses Pepto-Bismol is drinking Bismuth. In the early 90s the Dept of Defense banned Antimony in solder but later repealed the ban. I drained the waves and the hot air solder leveler and replaced the solder with "No Antimony" solder. Ther

okay so both the 2005 formulas from interflux are clear alchol based fluxes. Yellow res huh? In looking at the temps here, I would say you might be too hot at both preheat and solder temp. You may be burning flux. How long is dwell time over wave

If you bought this camera from Universal, it should come focused correctly. I had one of the first 0.5 mil cameras for flip chips. I used it for years and it was out of focus. I finally convinced Universal that something was wrong and they replace

Sounds like your PCBs are now white tin. Change this to another roHS compliant finish and see if prob goes away. You must get control of the materials that you are being asked to build. Your Customer needs your advice on surface finishes, they sho

I just converted our waves from an old alcohol-based flux to a new VOC-Free Water-based flux. The results have been startling. However, the ladies at post-wave inspection are complaining that the solder joints are too shiny, and it hurts their eyes

SN100C is designed not to corrode your pot, and can be used on standard solderpots (after a proper clean out), whereas SACX is still corrosive and if the coating is compromised then could cause problems. Get it in writing from the supplier that the

Cost will first and foremost be your deciding factor here. Cant go wrong with Electrovert or Soltec. TD has some decent stuff. As far as beoing comaptible, most all mfgrs are now making only pbfree comapatible. it seems to cost about $8 - 12k to

The low cost option would be to buy an old Electrovert with a spray fluxer & fill with SN100C. Saves cost of conversion, and you can pick up old, decent machines very cheap. Talk to whoever sells SN100C where you are in the world and go see some cus
