TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance with the

schedule of “IEC publications 60115-1 and 60115-4”,

category 40/200/56 (rated temperature range

−40 °Cto

+200

°C; damp heat, long term, 56 days). The testing also

covers the requirements specified by EIA and EIAJ.

The tests are carried out in accordance with IEC publication

60 068, “Recommended basic climatic and mechanical

robustness testing procedure for electronic components”

and under standard atmospheric conditions according to

“IEC 60 068-1”, subclause 5.3.

In Table 5 the tests and requirements are listed with

reference to the relevant clauses of

“IEC publications 60115-1, 115-4 and 68” ; 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.

All soldering tests are performed with mildly activated flux.
