6. Antenna Recommended Soldering Conditions

6.1. Flux, Solder

• Use rosin-based flux. Don’t use highly acidic flux with halide content exceeding

0.2wt%(chlorine conversion value).

• Use Sn solder.

6.2. Reflow soldering conditions

• Pre-heating should be in such a way that the temperature difference between solder

and product surface is limited to 150℃ max. Cooling into solvent after soldering

also should be in such a way that temperature difference is limited to 100℃ max.

Unwrought pre-heating may cause cracks on the product, resulting in the

deterioration of products quality.
