6.Environmental Characteristics
Items
6-1.High Temperature
Storage Test
Preliminary
Conditions
Keep in a chamber at 85
±2°C
for 1000 +12/-0 hours, and then keep at room
temperature for 1 hour. The characteristics of shock sensor shall meet the
specifications.
6-2.Low Temperature
Storage Test
Keep in a chamber at –40
±2°C
for 1000 +12/-0 hours, and then keep at
room temperature for 1 hour. The characteristics of shock sensor shall meet
the specifications.
6-3.Moisture
Resistance Test
Keep in a chamber at 90 to 95 % R.H. and 60
±
2°C for 500 +12/-0 hours,
and then keep at room temperature for 1 hour. The characteristics of shock
sensor shall meet the specifications.
6-4.Temperature
Cycling Test
Apply 100 thermal cycles with the following temperatures:
-
-
-
upper temperature 85°C for 20 minutes and transfer time 10 minutes
lower temperature -40°C for 20 minutes and transfer time 10 minutes
total cycle time is 1hour
and then left at room temperature for 1 hour. The characteristics of shock
sensor shall meet the specifications.
6-5.Mechanical Shock
Test
After applying the acceleration at 29430m/sec
2
{3000G} in each of X, Y and
Z axis (each 3 times). The characteristics of shock sensor shall meet the
specifications.
6-6.Solderability Test
At first, being soaked in the Methanol solution containing Rosin for 5
seconds and then being dipped in a bath of Pb/Sn solder at 250
±
5°C for 4
±
0.5 seconds. The surface of the electrode terminal shall be soldered more
than 95%.
6-7.Resistance to
Soldering Heat Test
Pre-heat temperature is 150 to 180°C for 1 minute. High temperature is 250
±
5°C, over 200°C for 20 seconds max.(2times). Then keep at room
temperature for 1 hour. The characteristics of shock sensor shall meet the
specifications.
6-8.Board Flex Test
