Electrical connector for connecting an adaptor board or electrical component to a main printed circuit board
An electrical connector electrically connects either an adaptor board or an electrical component to a main circuit board through the use of a thin printed circuit having an array of pads one each side where on one side the pads are connected to a main circuit board by solder balls, solder columns conductive epoxy or any other way practiced in the art and on the other side of the thin circuit the pads are connected to an adaptor board by a conductive compliant elastomeric material. The sides of the thin printed circuit are electrically connected to one another in ways practiced in the art.
1 . An electrical connector for providing an electrical connection between an adaptor board and a main circuit board, comprising:
an electrical connector formed as printed circuit board having an array of pads on its top surface and on its bottom surface with conductive elastomeric material on top of said pads on surface for connection to an adaptor board and with suitable conductive material on said other surface for electrical conduction with a main circuit board wherein said pads on each side of said electrical connector are electrically connected to each other to provide connection between said adaptor board and said main circuit board.
2 . The electrical connector according to claim 1 wherein instead of an adaptor board an electrical component is connected by said electrical connector to said main circuit board.
3 . The electrical connector according to claim 1 wherein said elastomeric material is anistropic elastomeric material.
4 . The electrical connector according to claim 1 wherein said elastomeric material is isotropic elastomeric material.
5 . The electrical connector according to claim 1 wherein said printed circuit board includes a compression hard stop formed of a dielectric material to prevent over compression of the elastomeric material thereby preserving longevity of the elastomeric material and preventing the elastomeric material from shorting adjacent pads.
6 . The electrical connector according to claim 5 wherein said dielectric material is formed of Kapton.
7 . The electrical connector according to claim 1 wherein said pads on said top surface of said printed circuit board has aspirates as well as the elastomeric material for attaching the elastomeric material to the adaptor board.
