hi, can anyone share experience on PCB open trace repair? we have some data that indicates that this repair is high risk and really very dependant on repairer skills. It may also cause reliability issue for trace repair. please advice.

Since we build produt and co not repair, we send our damaged boards to a place that specializes in board repair.

If you kink the leads will you be able to insert it without flexing the board/moving any of the other components? Also these pin headers aren't always designed for this process so have you checked that it will take the elevated temperatures?

I agree with verifing this part is even high temp reflow compatible. The age of the original dwg release, 1986, and as there is no mention of high temp reflow compatibility, only a mat'l call out of nylon, leads me to think it is not.

We had to replace the chains on our Omni as well. We used a non-approved oil which build up so much carbon the links would not move. Since using the high temp oil they recommend, no problems.

I had a similar problem once. It turned out to be sprocket bearings. The sprocket was so hard to turn, the chain would stop a couple times per shift.

We use the Tribol 930/100 Synthetic oil. Also, check the drive motor chain on the output end of the oven. I have seen the set screws back out of the drive gears, and it will kind of pop at times while running.

Great advice, all. Thanks much. I called on the Tribol 930 and there is now a blend called Tribol 1421 that is good for higher temps. Speedline recommends in place of 930 if you wish to do so. Might be something to consider for lead free stuff.
