Beschreibung
Zusammenfassung:	The invention relates to an intermediate support for electronic components, for example a semiconductor, comprising a plastic substrate with contact bumps (2) in one-piece, covered with a metallic layer, which is electrically connected to at least one conducting path of said substrate (1). Said contact bumps (2) each comprise a well wettable path, extending from the tips to the base thereof and each leading to the corresponding contact bump (2) base in a solder receiving region with suction (11). Therefore, by soldering said contact bumps, excess solder can be sucked off, such that short circuits can be avoided even without the use of a solder resist. By solder contacting said intermediate support, the solder can thus be applied over a large surface on a circuit support and sucked off the cavities between the contact points by reflow soldering.
