Check cure of solder resist. Use a No clean low solids rosin flux this will stop problem. Should see almost zero solder balls if put through a single wave compared to a dual wave. If this is true then it is a resist issue and cannot 'resist' the sold

We are using Mulicore MF101 flux and a Vitronics selective soldering machine on a lead-fee assembly and are having trouble with nozzles blocking even when the nozzle aperture is increased. Has anyone come across this problem before using fluxes with

If you have flux deposits on the cooling plates, try out Zestron's VIGON RC101...It is an extremely good product especially for reflow ovens and wave solder systems. Check it out...Minimal maintenance water based chemistry with no flash point...Much

saturation occurs at ppm levels. Remember, IPA is extremely flammable and its bulk use makes the plant liable to all sorts of quite repressive safety rules/regulations and so on. Ignoring these rules exposes the owner to fines and possible plant cl

Wes, I have been involved with many customers changing over from an alcohol based no-clean to a VOC-free process. The change-over can be made easier by such things as air movement, convection preheat, "drains" or reliefs in pallets (if used), contr

Hi Dave, If my solder paste is RMA based and my Wave Solder flux is NC Based, will there be incompatibility problem that might arise during the process? thanks

Hi Dave, If my solder paste is RMA based and my Wave Solder flux is NC Based, will there be incompatibility problem that might arise during the process? And if i don't clean my boards what will be the possible effects of the residues left? thanks

DO NOT Mix Technologies.... If you are using a no clean solder paste use a no clean wave solder process. I have direct experience with using a no clean paste and a RA water-soluble wave solder process. When cleaning with the water wash system your
