An old quad 2C/4C with a workholder will probably fit all those numbers. 2Ft is pretty long though and that might be a little too long. Machine price range is about right. Programming is pretty easy. Good luck

maybe the pcbs need a proper dry (the quick dry in the reflow oven won't get all the moisture out )...maybe 125 C for 4 hours or speak to the manufacturer to get their recommendations.

Patrick, It actually seems to go away after every adjustment. Whether it's flux, heat, doesn't matter but it always reappears. The part that has me baffled is the fact that another identical part is approx. 4 mm away, and never affects this one.

I would contact one of your solderpaste manufactuers. (i.e Indium, Alpha Metals, Kester, etc)

Try Easyspheres (Kester), or Q-Pearls (Qualitek), or Alpha. They all have solder spheres in that alloy.

Thanks everyone. I was having a hard time to find someone with immediate stock, reasonable price, lead time, or min order. I found some though and have extra stock now if anyone needs some.

Here's a start 1. Eliminate nonconforming material 2. Eliminate parts shortages 3. Reduce configuration changes 4. Stop rework, software changes 5. Eliminate assembly errors

You should look at Amtech Solders. They have excellent no-clean fluxes that are designed to be water washable if desired. We have been using them with great results for about 4 years now.
