7 / 10 page Item Test Method Criteria for judging RELIABILITY TEST METHOD Resistance to Soldering Heat Test Solderability Test Adhesion Resistance to flexure of substrate Dry Heat Test Cold Test Damp Heat Test (Steady State) Thermal shock Test Soldering temperature : 260¡ 5oC Duration of immersion : 10¡ 1sec. Preheating : 150¡ , 1min. Soldering temperature : 230¡ 5oC Duration of immersion : 5¡ 1sec. Preheating : 150oC, 1min. Force W is applied to DUT. The middle part of substrate shall, successively, be pressurized by means of the pressurizing rod at a rate of about 1§fi/sec. Maintenance time : 5 sec. Bending distance : 1§fi Test temperature : 125¡ 2oC, 85¡ 2oC (R-T curve Z) Test duration : 1000+48hrs. After completion of the test, leaving the sample under the standard conditions for 24¡ 2hrs. Test temperature : -30¡ 2oC Test duration : 1000+48hrs. After completion of the test, leaving the sample under the standard conditions for 24¡ 2hrs. Test temperature : 60¡ 2oC Test relative humidity : 90¡›95RH% Test duration : 1000+24hrs. After completion of the test, leaving the sample under the standard conditions for 24¡ 2hrs. This cycle is repeated 1000 times. After completion of the test, allow the sample to stand under the standard conditions for at 24¡ 2hrs. Visual : No mechanical damage Zero-power resistance at 25oC Change as against pretest values within ¡ 3% Change of B-value : within ¡ 2% At least 75% of the electrode must be covered with new solder. 2012 : over 2.0 kg f 1608 : over 1.0 kg f 1005 : over 0.7 kg f Visual : No mechanical damage Zero-power resistance at 25oC: Change as against pretest values within ¡ 3% Change of B-value : within ¡ 2% Zero-power resistance at 25oC: Change as against pretest values within ¡ 3% Change of B-value : within ¡ 2% Zero-power resistance at 25oC: Change as against pretest values within ¡ 3% Change of B-value : within ¡ 2% Zero-power resistance at 25¡ : Change as against pretest values within ¡ 3% Change of B-value : within ¡ 2% NTC Thermistor SMD 13 www.lattron.com |
