10.2 Flux, Solder
Flux
・Use rosin-based flux.
・Don’t use highly acidic flux with halide content exceeding 0.2(wt)% (chlorine conversion value).
・Don’t use water-soluble flux.
Solder
・Use Sn-3.0Ag-0.5Cu solder
・Standard thickness of solder paste : 100μm to 150μm
Other flux (except above) Please contact us for details, then use.
10.3 soldering conditions (Reflow)
･ Pre-heating should be in such a way that the temperature difference between solder and product surface is
limited to 100°C max. Cooling into solvent after soldering also should be in such a way that the temperature
difference is limited to 100°C max.
Insufficient pre-heating may cause cracks on the product, resulting in the deterioration of product quality.
Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and / or resulting in the
deterioration of product quality.
