This VIP70 has thermocouple inputs, so I'm hoping that's a good enough profiler. I tried a fairly different profile than you mentioned, so will test your settings today as well. If anyone has opinions, please jump in. Thanks!

That's very helpful, and much appreciated. I know it's a long shot, but I don't suppose you know what paste they are using with these settings. I am testing with sn100c ws488. Thanks! kinos

Hello We use a 5 zone conceptronics HVN70 and never before have we had something we could not do including 6 layers Rohs complicated boards. Recently we had a larger - simple 2 layer board - all 1206's etc however there are 15 pcs of a LARGE high m

Pad design is not only the size of pad but also the distance between two pad. N2 will increase tombstone as we tested. 10 zones reflow oven and slow temperature ramp will reduce this defect. MustII is the equipment which is used to test the solderabi

hello, we are profiling with the pcb each day - results are very good with a small delta we made another test board with TC only in the problem places - same good result we tried 500-600 boards on 12 zone machine - zero defects while on standard 6

Dear, Now we have some problems related to flux inside Reflow oven (Tamura oven, 7 zones). Flux drop on PCB so much. It has 2 kind of flux: wet and dry. We did maintenance cleanly reflow oven but it still happen. We are planning to test new setting o

Thanks for the replies. Interesting white paper. Didn't quite answer my concerns but still a good read. I was actually surprised that to test temperature uniformity across the zone, they attached T/C's to the substrate rather than measure the ai

I have an application that requires soldering pieces of metal (copper plate and copper fins to make a heatsink). Each piece is about 1 lb. I cannot test it in our reflow oven (5 zone) since the piece is about 3" in height. Has anyone attempted to

Hi Charly, For batch ovens there is no discussion. For inline loading interval depends on the oven you use, the amount of heat the PCB takes out of the zone and the capability of the oven to get it back in. The approximate time for the PCB to stay i

I'm testing SN100C, and with our 5 zone oven I seem to be able to fix one issue by changing the profile, but that might introduce a new problem. Some profiles work very well on most components, but have issues on other components. These are usually 0
