Instruction Manual

Desoldering wick is a braided wire coated with non-
corrosive rosin flux. It is the simplest and safest tool
for removing solder from a solder connection. When
the braided wire is heated, the flux cleans and
breaks up the surface tension so the melted solder
from the connection flows into the braid by capillary
action.
Included in this kit is a six inch length of solder wick
(desoldering braid).
Using the Desoldering Wick
1. Place the wick against the solder with the tip of a
hot soldering iron (see Figure 13).
2. The molten solder is sucked up into the wick by
capillary action.
3. When the iron and wick are removed, the solder
should be removed. You need to repeat the
process if some solder remains.
If necessary, repeat the procedure until all of the
unwanted solder is removed.
After the excess solder has been removed, clip off
and discard the solder-saturated portion of the braid.
For best results, always use a fresh area of the braid
for each procedure.

RESISTOR READING EXERCISE
Before starting assembly of your solder practice project, you should be thoroughly familiar with the 4-band color
code system. Many of the resistor values will be identified by color bands and it is easy to mistake their value
if you read the colors incorrectly or read the value from the wrong end. Do the following exercise in resistor
values. Place your answer in the box beneath the resistor. Answers are on the bottom of this page.
