Hello, Could anyone provide some support concern issue with vertical fill of through hole solder. Our lead free wave soldering process is not capable to fill 100% (requirement of our customer)through hole. We made everything (DoE) - different amoun

Alot of folks are going to experience this with their poorly designed desoldering systems. I would check the temperature that is being delivered at the tip of the desolder gun. A small preheater is recommended. The other problem you will encounter is

Anyone have problems wave soldering white tin finish? We are an ems and our customer provides us the pcb's. SMT and TH components on the board. SMT is fine but when we wave solder, wetting to top side is very poor (solder only flows half way up). We

At the wave, you should collect data on the critical process parameters. The cliche being, it's better to control your process via SPC versus performing SPC on defect data. Perform a DoE to determine which variable interactions have the greatest eff

Yes, doing the DoEs on your wave to achieve optimum settings that deliver the best results on your worst board is correct method. If not clear on the process, there are still wave solder process classes out there you can attend or hire in-house. If y

What happens is: we generate a profile that works and it is fine. however, If we run this profile continously say for an ECO upgrade or something where we are not just doing 1 or 2 we find that as we continue on the profile gets hotter and hotter i

Hi Everyone, I searched and found some old comments about the Novastar machines. I was wondering if anyone has purchased a newer one and used it for Lead Free? If so what do you think? We currently run 2 Technical Device machines (leaded) and hav

Hi. I agree that the Soltec has weak, low-wattage preheaters, and also, the Soltec's fluxer is flippin' weak too. It doesn't do a good jab of atomizing the flux and getting good, huh-huh, penetration on the holes. I cranked up my Soltec's pressu

I have been looking into buying a rework station like ERSA or PDR. What I am questioning is how well will these systems reflow BGA's with metal top/cover that are reflective. In addition, when preheating the board would dark body packages absorb te

I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a
