Hello there, I just want to ask you how often do you take your profiles on the Reflow Oven and Wave solder? I have a HMLV line running 5-6 products per shift (Reflow Oven & WS) my tech spend too much time checking the profile, but no major difference

No-Clean has less activators, your profiling Does change. Look at the data sheet supplied by the solder manufacturer. Then tweak the profile based on your equipment, board type, size etc. Don't burn off the activators too quickly. Also keep your chem

Hi, I was just hired on and put in charge of the wave machines. One lead and one no lead (lead free). My company currently does not have a wave profiler. He wants me to jury rig the re-flow profiler to work on the wave. I really think we need one ma

What does the reflow profile look like , the question I had was surrounding the higher reflow temperature and the max temperature that lowest thermal mass components will see. Some other questions that I had were surrounding the components , what of

Recently there was a thread on soldering paladium leads on ICs. A gent from TI suggested an article he had written. Various folks suggested making sure the reflow profile peaked above 215C. My question is: How does one recognize paladium leads so

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

The mask/copper layer is exhibiting popcorn blistering following reflow. With profiling we know that the assembly does not see anything close to 250 C, rather around 238 C.

Gary Getting the specs for a used machine will be tough from Ersa but at least send them a note, the seller should also be able to get the info for you. In regards a 5 zone system. I would suggest at least 7+ zones if your moving to lead free.

It seems that sceening at -20�C and using a vibration profile similar to the one you mentioned does a good job of high-lighting defective solder connections on assembled boards, but not affecting good connections. Why is this happening? In there a
