The problems we saw had to due with the Flux I believe. We saw what I would call poor coelescence and the residues were very hard for us to clean with our Water only cleaner. I will not lie and say I worked on the process very much. Since we alrea

Need help on selecting the SMT equipment for small volume

It looks like the 330 Convection & the GF120 ovens would really stuggle to do lead free, with 3 zones (the 330 has 3 top, 1 bottom). Can't comment on the 545 oven, you'll have to get them to run profiles with a selection of your boards & check on

Without knowing how much you use or what you use it for or what brand and which type, hard to say. In general, follow the Manufacturers recomendations. If you are doing precision work then use cartridges and let them warm up to room temp for a few ho

If no-clean...then this seems "relatively" normal. You could try and extend your peak and duration, however, manufacturers are adjusting their chemistry to survive these normal temperatures (up to 260C and 30 seconds within 5C of peak). You will h

Sorry to hear of your problems with your VPI-1000. As most people know the VPI line was transfered over to the Easy Braid Company last July. With most changes of this type there can be some initial confusion and and unneccessary stress placed on endu
