Desoldering Tips:
If you make a mistake and need to remove a part, follow these
instructions carefully! First, grasp the component with a pair of
hemostats or needle-nose pliers. Heat the pad beneath the lead you
intend to extract, and pull gently. The lead should come out. Repeat for
the other lead. Solder may fill in behind the lead as you extract it--
especially if you are working on a double-sided board with plate-through
holes. Should this happen, try heating the pad again and inserting a
common pin into the hole. Solder won't stick to the pin's chromium
plating. When the pad cools, remove the pin and insert the correct
component. For ICs or multi-pin parts, use desoldering braid to remove
excess solder before attempting to extract the part. Alternatively, a low-
cost vacuum-bulb or spring-loaded solder sucker may be used. Parts
damaged or severely overheated during extraction should be replaced
rather than reinstalled.
Work Habits:
Kit construction requires the ability to follow detailed instructions and, in
many cases, to perform new and unfamiliar tasks. To avoid making
needless mistakes, work for short periods when you're fresh and alert.
Recreational construction projects are more informative and more fun
when you take your time. Enjoy!
