10. Notice

This product is designed for solder mounting. (Reflow soldering only)

Please consult us in advance for applying other mounting method such as conductive adhesive.

10.1 Land pattern designing (Reflow Soldering)

Recommended land pattern for reflow soldering is as follows:

It has been designed for Electric characteristics and solderability.

Please follow the recommended patterns. Otherwise, their performance which includes electrical performance or

solderability may be affected, or result to "position shift" in soldering process.

10.2 Flux, Solder

・Use rosin-based flux.

Flux

・Don’t use highly acidic flux with halide content exceeding 0.2(wt)% (chlorine conversion value).

・Don’t use water-soluble flux.

・Use Sn-3.0Ag-0.5Cu solder

・Standard thickness of solder paste : 100μm to 150μm

Solder

Other flux (except above) Please contact us for details, then use.

10.3 Reflow soldering conditions

・Pre-heating should be in such a way that the temperature difference between solder and product surface is limited

to 150°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 products 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.
