27、he I EC expresses the wish that all National Committees should adopt the text of the XE C recommendation for their national rules in so far as national conditions will permit. Any divergence between the I EC recommendation and the corresponding national rules should, as far as possible, be clearly i

Scope This standard applies to a group of relate
32、d rectangular, multicontact, two-part printed board connectors with male and female contacts in conjunction with either solder or solderless termi- nations (such as wrap type). All connectors have the same contact spacing using the basic grid of 1.91 mm (0.075 in). The free connectors feature a rela
33、tively new method for the attachment of the connector to the printed board. It is accomplished with a series of cantilever solder tabs, which are distributed evenly on both sides of the board. This new method was adopted to meet the following needs : a) direct replacement of a socket-connector by a
34、two-piece mother and daughter board connector mated set, without requiring major design changes in the packaging system ; b) easy access to both sides of a board without having to use plated-through holes; c) high density packaging, with components on both sides ofthe board, without the complication
35、 of staggered pins and termination pads. STD-BSI BS EN bOb03-4-ENGL A998 Lb24bb7 Ob77074 T3 N 603-4 IEC LNN Page 6 EN 60603-4 : 1998 LL 2.
