MECHANICAL PERFORMANCE TEST ITEMS TEST METHODS AND TEST CONDITION 9.1 Drop Test The specimen is measured for its frequency and resistance before the test. It is then dropped from a hight of 100 cm or more as a free fall object onto a hard wooden plate of 30mm or more in thickness. ( in accordance with JIS-C0044 ) 9.2 Vibration Test The specimen is measured for its frequency and resistance before the test. Most them into X,Y and Z axes, respectively, for the vibration test. Vibration condition: Frequency range ; 20～2000HZ Peak to peak amplitude : 1.52 mm Peak acceleration : 20G Sweep time : 20 minute / axis Pendicular total test time : 4 hours ( in accordance with MIL-STD-883F : 2007.3 ) The specimen is measured for its frequency and resistance before the test. Place the specimen on the belt of the converynace and let it pass through the reflow with the presetted temperature condition. After passing twice the reflow place,the specimen under the referee condition for -~2 hours and then measure its electrical performance. Temperature Condition of IR Simulation: The temperature range of the preheated section is setted at 150～180℃ for 60~120 sec. For the next section the temperature range is setted at 217~260℃ for 45~90 sec. and within this time range the specimen should be able to sustain at the peak temperature, 260+/-3℃ , for 10 sec long. ( in accordance with JESD22-B106-B ) Place the specimen in a pressurized container and pressurize it with the detection gas ( mixed gas consisting of 95% or more helium ) for at least 2 hours. Complete the measurement of the concentration of helium within 30 min after taking it out from the pressurized container. 9.3 Resistance to Soldering Test 9.4 Fine Leak Test ( in accordance with MIL-STD-883F : 1014.11 ) The referee condition .

CLIMATIC RESISTANCE TEST ITEMS 10.1 Low Temp Exposure Test TEST METHODS AND TEST CONDITION The specimen is measured for its frequency and resistance before the test . Place the specimen in the chamber and kept it at the temperature of - 40 ± 3℃ for 168 ± 6 hours . Take the specimen out of the chamber and measure itselectrical performance after leaving 1～2 hours under the referee condition. ( in accordance with JIS-C0020 ) 10.2 Aging Test The specimen is measured for its frequency and resistance before the test . Place the specimen in the testing chamber and keep it at the temperature of + 125 ± 3℃ for 720 ± 48 hours. And then take the specimen out of the chamber and measure its electrical performance after leaving for 1 ～ 2 hours under the referee condition . ( in accordance with JIS-C0021 ) 10.3 High Temperature & High Humidty The specimen is measured for its frequency and resistance before the test . Place the specimen in the testing chamber and kept it at the temperature of + 85 ± 5 ℃ and humidity of 85 ± 5 % for 168 ± 6 hours.and then take the specimen out and measure its electrical performance after leaving for 1～2 hours under the referee condition. ( in accordance with MIL-STD-883F : 1004.7 ) 10.4 Temperature Cycle Test The specimen is measured for its frequency and resistance before the test . Subject the specimen to the 100 cycles of temperature ranges stated below . High temp . + 125 ± 3 ℃ (15± 3 min). 2～3 min. 2～3 min. Low temp . -55 ±3 ℃ (15± 3 min). Measure its electrical performance after leaving it for 1 ～ 2 hours under the referee condition . ( in accordance with MIL-STD-883F : 1010.8 ) PERFORMANCE To satisfy the electrical performance .
