Note the following points when welding FPC flexible circuit board ‌ :
‌ ESD prevention ‌ : The FPC circuit board is easily damaged by electrostatic discharge (ESD). Therefore, wear an ESD bracelet, use ESD tools, and ensure that the working environment has appropriate ESD protection ‌.

‌ temperature control ‌ : During welding, baking and other operations, the temperature should be controlled to avoid excessive temperature resulting in FPC material deformation or damage. It is generally recommended to use appropriate temperature control tools to avoid direct contact with high temperature FPC surface ‌.



‌ welding tips ‌ : When welding with electric iron, keep the iron tip clean to avoid oxidation layer affecting the welding quality. Apply the solder evenly to the welding part during welding to ensure that the solder fully moistens the connection point between the FPC soft board and the battery. Avoid excessive solder buildup, so as not to form a short circuit ‌.

‌ welding time ‌ : The welding time should not be too long, otherwise it will easily cause overheating of the FPC soft board and battery, and damage the internal circuit or battery structure. Soldering iron welding time should be controlled within a few seconds ‌.

‌ quality inspection ‌ : after the welding is completed, the quality inspection of the welding parts is carried out to ensure that the connectivity of each line is good and avoid problems such as virtual welding and short circuit ‌.

‌ environment requirements ‌ : FPC flexible circuit board has certain requirements for the storage environment, the temperature should be controlled below 25°C, humidity should be controlled in the range of 50%-70% ‌.
