Connector for a substrate with an electronic circuit

摘要

A connector (1) for connecting a substrate (2) with an electronic circuit to a printed circuit board (11) comprises a housing (4) of insulating material with a zone (5) for receiving said substrate. A main surface of the substrate is provided with contact balls (3) arranged in a given grid pattern with a predetermined pitch in column and row directions and the printed circuit board is provided with contact pads (10) arranged in the grid pattern. Through-holes (6) are provided in the zone in the grid pattern and contact members (7) are provided in at least a part of the through-holes. Further the connector comprises positioning means for locating the substrate with respect to the housing in such a manner that the through-holes of the housing are aligned with the contact balls of the substrate. These positioning means comprises at least one reference plate (12) which can be positioned on the housing (4), the reference plate comprising through-holes (13) arranged in the grid pattern for at least a part of the contact balls (3) of the substrate (2). Each reference plate and the housing are provided with cooperating coupling means (14-17) for accurately positioning the reference plate with respect to the housing.
