In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

Flux: Getting enough- is the spray fluxer getting good through-hole penetration. Try cranking it up. Soltec spray fluxers are not really as good as Ultrasonic Systems or Sonotek ultrasonics or the new ServoJET, but should do the job. Also, try anothe

Best dross remover is to not produce dross. Search the fine SMYnet Archives for previous discussions Dross will not increase signicantly * Another story, that lead-free solders will generate a greater volume of dross than conventional materials, is

I have a less than perfectly designed pcb requiring double sided lead free reflow. Several components from either side will detatch using the standard process. If I was using Sn63Pb37 I would just dispense some adhesive after paste and cure at the r

Hi, We have the Soltec Delta C. It works well, and is very stable. I think the software is a bit simplistic, but it keeps the wave stable, so that's the main thing. It's the timer on the software that I find annoying. It has a warm up time, and yo
