Claude, your not a manager by any chance are you?... you can't charge them for breaking them. Ok so yes there will be poor handling but if your going to fix the problem you have to look at teh route cause of it and fix that. You should be settign up

Mike, I've tried the high side of the flux preheat spec with no success. I did just get off the phone with Electrovert tech support...... Get ready. This machine is configured with a Contour Plus N2 nozzle. We are not running N2. According to M

SOT23 jumping off pads when reflowing

Hi all, by reading along those thread (SOT23) and Tan outgassing I learned plenty of things. My first time approacing this kind of Q$A Forum, very intesting tech communication way. Any way, the path of magnetism effect was chosen when time ago we met

Skewing of parts

We are having a problem with our Heller 1800W oven with certian parts skewing. It seems that some inductors and taller Can caps are shifting around in the oven. It seems it will solder fine and than all of a sudden just be off to one side or the othe

RB, We have a gold finger problem here at our plant. Our kapton tape came off in the wave process and now we have 8 PCB's that have silver fingers. We are waiting on our new A.P.E. SRS-069 Gold Finger Plater. This mircle machine is going to fix a

A process consists of much more than just thee machine. When developing a cause and effect diagram ffor the process, there are many parameters that fall outside the machine itself. There are Man, Machine, Methods, and Materials. Just monitoring th

Couple interesting articles on lead-free

Electronics Forum | Tue May 02 16:21:05 EDT 2006 | patrickbruneel

Grant, I personally disagree that lead-free can't be reversed. The reason it went that far is because lead has a bad reputation (lead in gas and in paint)and was probably assumed by the European green politicians as equally bad in solders. When they

Being a typically efficient Swiss based company Swatch started the task of RoHS conversion a year ago. After 2 years of intensive research they implemented the process in mass production in June 2005, they started shipping and found massive problem

I guess they finally figured it out (with 32 days left)

Interesting read, I guess they finally figured it out (with 32 days left) 2 quotes from the articles "What is surprising however � although it should not be � is that, despite the claims of health and environmental threats, the latter based on the r

Yield on 0402 SMT Printed Circuit Board Assemblies

99% good solder joints = 10000 ppm (defects per million opportunities). Having only built with 0603s I can't speak for a target but that still seems pretty harsh....with a 75/25 0805/0603 ratio at my last place of employment I think we were running
