> Back in my working career circuit boards were repaired. Now it is just replace it. are people getting dumber , or are they just too compilated now days?Our shop had a couple electronic guys. I could never do it. Stan
Good question, Stan. In a previous life I fixed circuit boards. In fact, I designed hardware and software for circuit board testing and fault diagnosis. These were for military weapons systems; the boards were expensive and designed to be repaired. I could probably figure out what's bad on my furnace's control board, but my time is worth more to me than the hundred bucks a replacement board costs.
There are a lot of reasons circuit boards aren't commonly repaired these days. As circuit density increases, the ability to repair gets more difficult. It was hard enough to replace components on single layer boards and it takes real skill to desolder and replace components on today's multi-layer boards. Documentation is usually hard to get; if you don't know how a circuit board is supposed to work it's difficult to troubleshoot it. Specialized components may be difficult to obtain, and in the case of microcontrollers if you don't have the firmware there's no way you can program a new microcontroller.
The bottom line is if you can buy a replacement circuit board at a reasonable price, it probably doesn't make sense to try to fix the old one.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
