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. Temp(°C) 5 sec (Peak 245°C) 240 °C 230 °C 180 °C 0° C 60-120sec 10-30sec Time (s) 5.3 Reflow with Soldering Iron • The following conditions must be strictly followed when using a soldering iron. Pre-heating 150°, 1 min Tip temperature 290° max Soldering iron output 30w max Soldering time 3 second max SPE-11-8-137/C/SS | page 8 of 9 6. Packaging SPEC NO.
