Desoldering Components (EE Tip #118)

Every engineer and technician sooner or later faces the challenge of having to desolder a component. Sometimes the component can be a large transformer with 10 pins or a power chip with many connections, and desoldering tools are typically around the $1,000 mark and above.

Chip Quik is a solder-based alloy that stays molten for up to 30 seconds and makes desoldering any component very easy. The only drawback is that the cost of a 2´ length of Chip Quik is around $20. But a little experience can make this go a long way. Having some Chip Quik lying around in the workshop is reassuring for when that urgent job comes in.
