Cleaning No-Clean Fluxes Prior to Conformal Coating

A customer called the Helpline seeking advice for cleaning no-clean fluxes prior to applying a conformal coating. The customer's assemblies were manufactured with a no-clean rosin based solder paste (ROL0) and were cleaned with an isopropyl alcohol (IPA) wash. After cleaning, a white residue was sometimes found in areas with high paste ...

Heller Reflow Oven Fan Noise -- We acquired a Heller 1809 MKIII and the fan on the bottom side of zone one makes a high pitched hum while the oven is at room temp. Once the oven starts to heat up, the noise goes away. The bearings were in bad shape, so we replaced those but it didn't fix the problem. We have found that if we lower the fan slightly, the noise goes away too but cant find anything that is interfering with the fan. Does anyone have any ideas?

Ersa Versaprint P1 Exploded View & Service Manual -- Hello Folks, We are desperately looking for exploded view and service manual for our Ersa Versaprint P1 screen printer. If anyone can help us it will be really appreciated. Regards Davide
