SGP25D Datasheet, PDF (10/11 Pages) List of Unclassifed Manufacturers – GPS SMT Patch Antenna

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.
5.3 Reworking with soldering iron
• The following conditions must be strictly followed when using a soldering iron.
