IEC 60352-5:2012 pdf Solderless connections – Part 5: Press-in connections – General requirements, test methods and practical guidance
1 Scope and object
This part of IEC 60352 is applicable to solderless press-in connections for use in tele-
communication equipment and in electronic devices employing similar techniques.
The press-in connection consists of a termination having a suitable press-in zone which is
inserted into a plated-through hole of a double-sided or multilayer printed board.
Information on materials and data from industrial experience is included in addition to the test
procedures to provide electrically stable connections under prescribed environmental
conditions.
The object of this part of IEC 60352 is to determine the suitability of press-in connections
under mechanical, electrical and atmospheric conditions as specified by the manufacturer of
the press-in termination and to provide a means of comparing test results when the tools used
to make the connections are of different designs or manufacture.
