摘要

Can I get that part out of there? That's a question many of us have asked ourselves while try-ing to remove an IC from a modern multilayer PC board. Gone are the days when all you had to do was heat up your hefty soldering iron, melt the joint and pull the wires loose. Nowadays, you're likely dealing with PC boards often having two or more layers, and find the solder joints are hard to melt and easy to damage. If you're working slowly, removing a 40-pin IC properly can easily take half an hour. That's probably $30 worth of technician time, including overhead expenses. Few ICs are worth that.
