11. Notice

This product is designed for solder mounting.

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

11.1 Land pattern designing (Reflow Soldering)

Recommended land patterns for reflow soldering are as follows:

These have 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.

(in mm)

11.2 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

11.3 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.

11.4 Reworking with soldering iron.

The following conditions must be strictly followed when using a soldering iron.

Pre-heating 150°C,1 min

Tip temperature 350°C max.

Soldering iron output 80W max.

Tip diameter φ3mm max.

Soldering time 3(+1,-0)s

Times 2 times

Note : Do not directly touch the products with the tip of the soldering iron in order to prevent the crack

on the products due to the thermal shock.

11.5 Solder Volume

・Solder shall be used not to be exceed the upper limits as shown below.

・Accordingly increasing the solder volume, the mechanical stress to Chip is also increased.

Exceeding solder volume may cause the failure of mechanical or electrical performance.

11.6 Product's location

The following shall be considered when designing and laying out P.C.B.’s.

(1) P.C.B. shall be designed so that products are not subject to the mechanical stress due to warping the board.

［Products direction］

The electorode part of the products should be

located like the picture to the mechanical stress.

(2) Products location on P.C.B. separation

Products (A,B,C,D) shall be located carefully

so that products are not subject to the

mechanical stress due to warping the board.

Because they may be subjected the mechanical

stress in order of A>C>B

≅ D.

11.7 Cleaning Conditions

Products shall be cleaned on the following conditions.

(1) Cleaning temperature shall be limited to 60°C max.(40°C max for IPA.)

(2) Ultrasonic cleaning shall comply with the following conditions with avoiding the resonance phenomenon at

the mounted products and P.C.B.

Power : 20 W / l max. Frequency : 28kHz to 40kHz Time : 5 minutes max.

(3) Cleaner

1. Alternative cleaner

・Isopropyl alcohol (IPA)

2. Aqueous agent

・PINE ALPHA ST-100S

(4) There shall be no residual flux and residual cleaner after cleaning.

In the case of using aqueous agent, products shall be dried completely after rinse with de-ionized

water in

order to remove the cleaner

(5) Other cleaning

Please contact us.
