Hi everyone! I've been lurking and trying to read the whole post and am only half way through. But checked out the latest posts to see what's happening.
I noticed that Paul is going to a surface mount control board and read about having the processor soldered directly to the board and the comments on it being difficult to replace. I worked at IBM years ago and we used microscopes, tweezers and a fine tipped iron to remove and replace components with fine pitch leads. It's not impossible to do but does require magnification (although not on all parts).
I have a suggestion, if it's possible. Does the Microchip processor come in a PLCC package? If so, you could place the PLCC socket on the board and just plug the processor into it. Then, if it needed to be replaced you just pop it out and plug in the new one. It may be a pain to lay out the board again, but would be a decent solution. You could also do this for other IC's that may need to be replaced often. Don't do this for IC's you don't have trouble with. Just a suggestion....
Anyway, Paul and everyone else here, you should be proud of yourselves for what you have accomplished for the EV enthusiasts! Great job!!!!
Jim
