5. Antenna Recommended Soldering Conditions
5.1 Flux, Solder
?
?
Use rosin-based flux. Don’t use highly acidic flux with halide content exceeding 0.2wt%(chlorine conversion value).
Use Sn solder.
5.2 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.
