New to thermal profiling (leaded and lead free), and my boss wants me to search for a better profiler. Currently our model has three ports for thermal couple inputs. We are established in our noraml process but we are relatively new to incorperate m

The formula is a great help, where was it 20 years ago? LOL After running a few thousand different products over the years, you start to get a feel for what is going to be trouble with regards to falling off the bottomside during the secondary refl

Dear all: For PBGA replacement by a hot air BGA rework station, do I have to follow the same temperature profile as the first original one in the reflow oven? Note that in the rework process I use only Flux paste (no solder paste is used). Hany

I sewed a sock out of a Nomex/Kevlar blend fabric because we had the same problem with our profiler. It works great. After one run through the reflow oven, the internal temp rises by about 5 degrees C. It used to go up by about 20-25 C. I can pic

I recently started a company that uses BTU Pryamax reflow oven (7 heat zones, 2 cooldown). Any advice on creating profiles for both leaded and lead free products? also what can you tell me about oven profiling with this model? i'm told it has buil

Your solder paste manufacturer’s profile is just a “guideline.” You can customize your profile to meet your product’s need. For better grain-structure (shiney-ness) try a ramp soak spike profile keeping your preheat temps very low before your reflo

| WE ARE CURRENTLY HAVING PROBLEMS REFLOWING BOARDS WITH WHITE TIN PLATING. WE ARE NOT GETTING GOOD WETTING ON THE PADS. | WE HAVE CHECKED THE REFLOW PROFILE AND TRIED DIFFERENT PASTE'S. | WE THINK THERE MAY BE CONTAMINATION OR OXIDATION ON THE PADS.

My company, ETS, is a manufacturer of solder reflow and curing ovens. I would be happy to share some of our q/c test methods with you for verifying the uniformity and repeatability of the new ovens we manufacture. I think these tests will tell you al

| At this moment in time we are using water soluble solder paste on our PCBs these are cleaned using water only, agitated with ultrasonics. After drying a white/grey residue is left around solder joints. Reflow profile is fine and a reliable wash pro
