PCB profiling

I was curious what others in pcb assembly are doing as far as profiling. Is profiling an important part of the smt process? Should every board type processed be profiled to determine optimum oven temps per paste recommendations.Is it ok to assume tha

You should definitely profile your new BGA containing PCB with a real profiler with attached thermocouples. I would actually drill a hole under the BGA and put a thermocouple there.BGAs usually require longer profiles with longer soaks zone.....and s

Thanks for your input Rob, Our operator does not profile pcb's which so far we have not had issues that could be attributed to his oven settings. We may be running a pcb with a BGA on it and I was concerned about our lack of profiling. I have spent q

I'm with Evtimov...if you've got a new assembly with a BGA (and especially if BGAs aren't an every day occurrence in your process) it should definitely be profiled. I have run BGA boards without profiling before, and got lucky...but, I wouldn't reco

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

What would be a recommended way and were to attach therms for profiling on a board with a BGA or BGA's. Evtimov had mentioned drilling a hole and attaching to the BGA? We do not always get sacrificial boards when we do a job. Is attaching to the PCB

Drilling a hole, and attaching the thermocouples underneath the part is the recommended way to profile for a BGA, unfortunately. It allows the best method of collecting specific data, including any thermal sinking/shadowing that the BGA creates. Ho

A good resource for implementing a BGA assembly process is: IPC-7095C Design and Assembly Process Implementation for BGAs Lots of valuable information in that publication.

what are the methods used out there to verify reflow oven performance or machine profiling. What intervals are good practice and is it necessary. We do product pofiles with our profiling equipment and can that be used to base your machine performance

Hi, I will give just one of the couple of ways I have seen. Once a particular product is debugged, verified through the process the profile of the Oven and it's settings are stored on a separate PC. Prior to running that product and at the start of
