Items

Specifications

Test Methods

Vibration Resistance

No severe damages

Solder specimens on the testing jig (glass fluorine

boards) shown in appended Fig.1 by a Pb free solder.

The soldering shall be done either by iron or reflow and

be conducted with care so that the soldering is uniform

and free of defect such as by heat shock.

Frequency

: 10～2000 Hz

Acceleration : 196 m/s2

Direction

: X,Y,Z 3 axis

Period

: 2.5 h on each direction

Total 7.5 h.

Shock

Solder specimens on the testing jig shown in

appended Fig.1 by an eutectic solder. The soldering

shall be done either by iron or reflow and be conducted

with care so that the soldering is uniform and free of

defect such as by heat shock.

Acceleration

: 981 m/s2

Period

: 6 ms.

Cycle

: 6 axis ×10 times

Deflection

Solder specimens on the testing jig (glass epoxy

boards) shown in appended Fig.2 by a Pb free solder.

The soldering shall be done either by iron or reflow and

be conducted with care so that the soldering is uniform

and free of defect such as by heat shock.

No damage with 1.6mm deflection

Soldering strength

(Push Strength)

2N Minimum

Solder specimens onto test jig shown below. Apply

pushing force at 0.5mm/s until electrode pads are

peeled off or product is broken. Pushing force is

applied

to longitudinal direction.

Solderability of Termination

95%

the

terminations is to be

soldered evenly and

continuously.

Immerse specimens first an ethanol solution of rosin,

then in a Pb free solder solution for 3±0.5 sec. at

245±5 °C.

Preheat

: 150 °C, 60 sec.

Solder Paste : Sn-3.0Ag-0.5Cu

Flux

: Solution of ethanol and rosin

(25 % rosin in weight proportion)

Resistance to Soldering Heat

(Reflow)

No severe damages

Satisfy specifications

listed in paragraph 7-

Preheat Temperature

150-200 °C

Preheat Period

: 90+/-30 sec.

High Temperature

: 217 °C

High Temp. Period

: 105+/-45sec.

Peak Temperature

: 260+0/-5°C

Specimens are soldered twice with the above condition,

and then kept in room condition for 24 h before

measurements.
