Performance Requirements

7-1 Mechanical

Shock

The transducer shall be measured after being

applied

three

impacts

plus

and

minus

directions

three

mutually

perpendicular

planes.

The shock is specified as 29400m/s

2(3000G)

half sine pulse of 0.3 ms duration.

No visible damage and the

measured values shall meet

Table 2.

7-2 Vibration

The transducer shall be measured after being

applied vibration of amplitude of 1.5 mm with 10

to 55 Hz band of vibration frequency to each of 3

perpendicular directions for 2 hours.

( 5 minutes

× 24 cycles )

7-3 Bend Strength

PCB

The transducer is soldered onto the center of

PCB (1.6 mm thickness) which is laid on the 2

small supporters spaced 90 mm.

PCB is deflected to 1 mm below from horizontal

level by the pressing force with 20

× 10. R10

stick. The force is supplied for 1 second, 5 times

repeatably.

No visible damage and the

measured values shall meet

Table 3.

7-4 Resistance to

Reflow

Soldering

The transducer shall be mounted on PCB, then

measured after being applied following reflow

conditions.

Pre-heating :

60 to 150 sec. at 150 to 180

°C

Heating :

Within 60 sec. at 200

°C (or more)

Within 30 sec. at 250

°C (or more)

Peak Temperature:

Within 10 sec. at 260

°C

Shock sensor should be tested 2 times of this

test flow.

PCB size

: 115

× 80 × 0.8 mm

After being placed at ambient conditions for 8

hours, the transducer shall be measured.

No visible damage and the

measured values shall meet

Table 2.

7-5 Solderability

End terminals are immersed in rosin for

5 seconds then immersed in soldering bath of

+230

±5°C for 3±0.5 seconds.

75% min. end terminals shall

be wet with solder.

7-6 Washability

See Table 1.

No visible damage and the

measured values shall meet

Table 2.
