Flexible Circuit Board Repairing

I Keep the temperature of the soldering iron around 270°C during
repairing.

I Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

I Be careful not to apply force on the conductor when soldering or
unsoldering.

Notes on chip component replacement

I Never reuse a disconnected chip component.

I Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
