Flexible Circuit Board Repairing
· Keep the temperature of the soldering iron around 270 °C dur-

· 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
