<p>In printed-circuit boards, which are intended for mixed fitment with wired and surface-mounted components, there arise sometimes difficulties in the bonding of large components and thermal problems, in overhead soldering in the wave soldering bath. …<??>In order to be able to provide printed-circuit boards for mixed fitment with PLCC components (7) as well, some of which can otherwise not be inserted, a printed-circuit board (1) was produced which is provided with a recess (19) for such components. In this case, the recess (19) is provided on its sides (5) with indentations (21), which are used for guiding and for making contact with the components which can be inserted. …<IMAGE>… </p> |
