•  Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing
•  Keep the temperature of soldering iron around 270 °C 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.
