We understand that testing for ionic contamination and surface insulation resistance measure different properties. We assemble printed circuit boards for other companies. We will not get combs on 90% of the boards that we assemble. We have no custo

The KIC Prophet system does indeed deliver as promised. The Slim-KIC (datalogger portion) works well and is worth the price of admission by itself. The Prophet portion of the system (resident in the oven) works great and decreases the requirement for

I am running boards with gold fingers on a pallet for masking purposes. The pallets worked fine for a while but know the gold fingers are getting solder on them. We have tried everythin: new pallets, cleaning the pallet and board to be sure there

The first thing is all the TSOP suppliers like Intel do not rate the parts at normal temperature used in wave soldering. The spec is less than 230C so you have the reliability issue to consider and no one to blame when they do not work. You also have

I thought this was a forum for equipment only. We were asked to take OUR messages off of the other SMTNet forum. I see many messages concerning process related issues that don't have anything to do about buying, selling or servicing SMT equipment.
