Thanks Ken for your reply. Concerning OSP, there are a few negative points that I must considered for our application. I've read all the following points in an Entek document. Never test it. - If you have a miss print and you clean the PCB, the co

Thanks, That's the direction i'm headed. After by passing relay altogeather, testing large caps for the driver supply, replacing bridge rectifiers, and the MOV's, that's about all im left with. The vacuum motor will run with the software toggle witho

It sounds like you already know the answer. Hand soldering is much more stressful to a board than mass soldering, because: * It is more localized and there is no preheat. * It is more difficult to control. [Different connections require different h

I do not mean big, heavy transformers but rather small ferrite core transformers, with ferrites in the range of EF16 .. EF40. The weight of the lead and its percentage of the total weight is not the issue here. We simply do not want lead-containing t

Do you have any parts dedicated on the machine? 100n 0603 or 0805 is probably used on almost everything you build. So why take it off and put it on the machine several times a day. Even if you dedicate only 20 parts to never come off the machine, tha

James, It's good that you have internal part numbers. Some CMs use customer part numbers which makes dedicated setups much more difficult. Your materials group can tell you the quantities of part numbers they buy, and that can tell you which parts

The mount plane is not the same every time. Our machines are conveyorized and the bottom rail is fixed so the mount plane does change with the board thickness. The stand alone table has a V notch for holding the board with the flat edge on the bottom

There have been times when we could have done with having a Ken or 2; He may not always agree with everyone but he has demonstrated a very good process knowledge over all the time I've been using SMT net. Also I've never read one of his posts that w

Hi, I would be interested in the data, and I after our experience with batch convection I am quite skeptical. I would be very interested in temperature plots. What I would like to see before I ever considered a batch convection oven is how the oven
