3. Installing the Leadless (chip) Component
1) Presolder the contact points of the circuit board.
2) Press the part downward with tweezers and solder both
electrodes as shown below.
4. Removing of Flate ICs (Recommendable manner)
1) For removing solder chips from IC's pins, use a solder
remover or a wiry solder absorber.
2) Heat the IC's tips evenly by moving the chip IC replacing
tool around them, and detach the IC's leads with a tool in
the way of using a lever.
3) Do not reuse ICs removed once (Discard them)
Note:
Do not glue the replacement leadless component to the
circuit board.
