Aerospace/military application- we have recently installed an SMT line. Our prior cleaning of RMA flux was Isopropyl Alcohol only, but with the reflow oven on line, the flux is now baked on. I am looking into FLUX OFF cleaner for removal of t

Hi Jeff, Glad to see you are still around. The two S's were my first port of call....you know how hard it is to knock new information into my head. Apparently there is no visual indication. They've suggested cleaning the unit with ISO etc but I think

We have Heller Reflow Model 1809 EXL. Today we opened it hood for internal cleaning but now not able to close them. Hood opened more from entry side. We tried to manually force open from exit side & check closing with open/close button, but hood comi

We still have an old Heller 1500W kicking around and I can't locate a parts list or manual. I know some "spring cleaning" went on and I'm wondering if someone tossed them. The main issue is the edge rail chains seem to suddenly have a lot of slack.

We did figure out the issue. The plastic cover inside the LED lighting unit had a slight film covering it, which made the picture slightly hazy. We had to disassemble the LED module to get at it, cleaned it and it was fine. I didn't think this would
