We use the same profiler for convection and VP. For VP you just have to be very careful as the thermocouple wires must travel through the machine so cannot get "snagged" on anything as they go in or come out.

Does anyone know of a method other than drilling holes in a board to accurately profile a BGA ?

Has anyone used a thermal profiler on a select solder program? We would like to know which brand anyone has had good results with. Thanks

Hello ! I have a vitronics 500s ( five zones), and the solder paste is ALPHA OM-338-PT lead free. have anyone a profile to start and test, i need some reference temperatures.and conveyor speed thanks !!!

Hi, when we change model from reflow temperature profile to temperature profile for glue, we always open oven to cool down. It is good for oven? Thank you for your answer.

We run the same profile for both sides. We also run the bottom temp 10C cooler in the final 2 heat zones.

Does anyone know of any good profile prediction software for free, trial or on the market that is not coupled with hardware. We want to specify the environment, paste, board and oven etc variables and have the software suggest the best cavern temper

Thank you for advice, But main concern how to detect the problems with BGA on SMT line, and how I can validate "good" or "bad" profile. PS: SPC said that process Cpk 2, temperature profile in the upper spec limit for TAL and peak temperature.

1. For PCBs we can do thermal profiling 2. Sensor needs to connect to the input pins. the pin no. depends on the sensor quality. 3. Proper input and compatible sensors should be used.

You must thermally profile your circuit boards with a data-logger and thermocouples. Just putting in oven set points and looking at solder joints is not enough. Reference IPC-7530
