7. Recommended Soldering Conditions
Product can be applied to flow and reflow soldering.
⑴
Flux, Solder
①
Use rosin-based flux. Don’t use highly acidic flux with halide content exceeding 0.2wt% (chlorine
conversion value).
②
Use Sn solder.
⑵
Flow soldering conditions
①
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.
