Crazy Solder Jobs
Sometimes you have a board, and that board works well, for what it was designed to do, except now you need to do something else. Not only would designing and building new boards be too expensive (some of the boards I've modified were $50K and up), but it simply would take too long to get the job done. After all when the customers are clamoring for data in a week, and it would take at least three weeks to re-spin the boards, and $$$$ (millions) are on the line, there is little choice but to "make it work". That's what I do.
