PRODUCT DESCRIPTION
Chem-Wik Rosin is especially designed for
today’s heat se nsitive electronic components.
The lighter mass, pure copper braid
construction allows for better thermal
conductivity, even at low temperatures.
Chem-Wik Rosin responds as much as 50%
faster than conventional desoldering braids.
This design minimizes overheating and
requires less “contact” pressure for greater
operator control. All sizes are coated with a
Type “R” or ganic flux system.
Requires little or no post solder cleaning
No corrosive residues
Optimized weave design for faster
wicking and heat transfer
Halide free
Minimal risk of heat damage to
components and circuit boards
TYPICAL APPLICATIONS

USAGE INSTRUCTIONS
For industrial use only .
Read MSDS carefully prior to use.
1) Choose a Chem-Wik desoldering braid
width equal to or slightly larger than the
pad or connection.
2) Choose a solder iron tip equal to or slightly
smaller than the pad or connection.
3) Set temperature of iron between 600-750°F
4) Place wick on solder joint and place tip of hot
iron on top of wick
5) As solder becomes molten, the color of the
wick will change from copper to silver.
6) Remove wick and iron from solder joint
simultaneously once color change has stopped.
7) The component lead is now clean and free
from solder.
8) Clip and discard the used portion of the wick.
