Hi, Guru, you are completely full of crap. I have had three MYDATA machines, and battled with accuracy the whole time we had them. We did every upgrade, and added the latest feeders and line scan cameras. In the end we could not keep the accuracy g

Hi, I believe you have classic gold imbrittlement here. With 80 microinches of gold you are way over the limit. You can try to reflow longer time and at a higher temperature. The gold does not melt into the solder joint. The gold dissolves into

I have never seen any industry standards for setting up an SMT assembly facility, but I�ll offer some basic advise. An ideal SMT assembly facility is one that is clean and well lit and has environmental controls to maintain temp and RH. Temp of 24C (

Having the last two zones at the reflow temp (spike) is typically done on long ovens (10 zone) running at high conveyor speeds. This enables you to achieve peak temp and TAL as per the solderpaste specs at high production rates. Concerning reverse sp

Hello Brad, We are running the Slim Kic 2000. We have found the predictions to be fairly accurate as long as the suggested change is within 20 degrees of the original recipie. As a test I ran a board with the wrong profile. The predictions got me wi
