With Chipquick
Another way to remove SMDs is with a special solder made by Chip Quik.The solder is an alloy of tin, lead, indium,
and bismuth. Bismuth has a very low thermal conductivity. If it is mixed with tin, the melting point is reduced to 65°C.
and so it becomes difficult to damage the PCB . Another advantage is that there is no additional desolder equipment
required.
It can be ordered with part number SMD1. This package contains chipquick flux , chipquick solder and alcohol
pads.
1
Apply flux to all pins of the
defective SCAN IC
4
Move the excess with the solder
iron to an unused section of the
PCB. Remove after it's cooled
down.
7
PCB is ready to mount the new
SCAN IC.
2
Adjust the temperature of the
solder iron to +/- 200°C and
melt CHIPQUICK alloy
uniformly on all pins.
5
Clean site with swab
dipped in flux while
applying heat.

3
Maintain the alloy in molten
state and remove the SCAN IC
with a pick - up tool.
6
At room temperature, clean the
residue with alcohol pad.
