29、tted without license from IHS -,-,- INTRODUCTION This part of IEC 60352 includes requirements, tests and practical guidance information. Two test schedules are provided. a) The qualification test schedule applies to individual press-in connections (press-in zone). They are tested to the specificatio
30、n provided by the manufacturer of the press-in zone (see 4.6) taking into account the requirements of Clause 4. The qualification is independent of the application of the press-in zone in a component. b) The application test schedule applies to press-in connections which are part of a component and
31、are already qualified to the qualification test schedule. Test sequences focus on the performance of the press-in connection which is affected by the implementation in a component. As the manufacturer of the press-in zone has to provide the main part of the information needed for qualification, the
32、use of the words “the manufacturer“ is implemented throughout this standard for simplicity. IEC Guide 109 advocates the need to minimise the impact of a product on the natural environment throughout the product life cycle. It is understood that some of the materials permitted in this standard may ha
33、ve a negative environmental impact. As technological advances lead to acceptable alternatives for these materials, they will be eliminated from the standard.

35、ess-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. Informatio
36、n 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 specified mechani
37、cal, electrical and atmospheric conditions. Only compliant press-in zones can be qualified according to this part of IEC 60352. Solid press-in zones are in use. Information about these is given in Annex A. 2 Normative references The following referenced documents are indispensable for the applicatio
