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
°
C to
+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
60068,
“
Recommended basic climatic and mechanical
robustness testing procedure for electronic components
”
and under standard atmospheric conditions according to
“
IEC 60068-1
”
, subclause 5.3.
In Table 4 the tests and requirements are listed with
reference to the relevant clauses of
“
IEC publications 60115-1, 60115-4 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.
