Flexible Circuit Board Repairing
* Keep the temperature of the soldering iron around
270 during repairing,
* Do not touch the soldering iron on the same conductor
of the circuit board (within 3 times).
* Be careful not to apply force on the conductor when
soldering or unsoldering.
Notes on chip component replacement
« Never reuse a disconnected chip component.
« Notice that the minus side of a tantalum capacitor may
be damaged by heat,
