The tests are carried out in accordance with IEC 60068-2-xx test method, “Recommended basic climatic and mechanical robustness testing procedure for electronic components” and under standard atmospheric conditions according to IEC 60068-1, 5.3. In the Test Procedures and Requirements table the tests and requirements are listed with reference to the relevant clauses of IEC 60115-1 and IEC 60068-2-xx test methods. A short description of the test procedure is also given. In some instances deviations from the IEC recommendations were necessary for our method of specifying. For inflammability requirements reference is made to IEC 60115-1. All soldering tests are performed with mildly activated flux. 100 0 0.2 0.6 0 0.4 20 40 60 80 P (W) ΔT (K) 50 0 0.2 0.6 0 0.4 10 20 30 40 P (W) ΔT (K) 15 mm 5 mm 10 mm 100 0 0.2 0.6 0 0.4 20 40 60 80 P (W) ΔT (K) 15 mm 5 mm 10 mm 50 0 0.2 0.6 0 0.4 10 20 30 40 P (W) ΔT (K) |
