Precaution in Soldering LCD Module

Basic instructions: Solder I/O terminals https://www.wendangku.net/doc/7115430339.html,e soldering iron without leakage.(1)Soldering condition to I/O terminals

Temperature at tip of the iron: 280±10℃Soldering time: 3~4 sec.

Type of solder: Eutectic solder (containing colophony-flux)

*Please do not use flux because it may soak into LCD Module or contaminate it.*It is preferable to peel off protective film on display surface after soldering I/O terminals is finished.

(2)Remove connector or cable

*When you remove connector or cable soldered to I/O terminals, please confirm that solder is fully melted. If you remove by force, electrodes at I/O terminals may be damaged(or stripped off).

*It is recommended to use solder suction machine.
