If your product mix is similar in terms of thermal mass and componentry, find some standard setpoints (by doing a baseline profile) which will produce a thermal profile that's within the specs. of your solder paste and product. This approach usually

I am in the R&D department at KIC. We have been making thermal profiling equipment for 20+ years. A standard circuit board is made from FR4 fiberglass. A typical solder reflow profile, whether leaded or unleaded, takes the board above the "glass t

As was stated before, you need to have oven temperatures (profile) set such that you get good solder joints with the paste you are using. And definately run a profiler through yor oven to verify it is working properly. As for components, most data

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

Funny, I just had this discussion on LinkedIn. Must be the season. It is always acceptable and preferably to profile every assembly, if you have the time, resources, and equipment to do it. That is the only way to get the most accurate information

A few lifetimes ago I went to a seminar on reflow profiles. The speaker emphasized more than once that the cool down rate is important. Someone asked him about controlling the cool down rate and he acknowledged that you can't. And IIRC it was an ove
