  • Patent number: 9184520
    Abstract: An electrical connector includes a base and an elastic terminal. The base has a recess. The elastic terminal is connected to the base and extends to the recess. The elastic terminal has a fixed end and a free end, the fixed end is connected to the base, and the free end is located at the recess and is curved. When the contact moves towards the recess, the contact is capable of pushing the contact protrusion to bend towards the bottom of the recess so that the free end leans against the bottom of the recess. The electrical connector may further include a contact protrusion connected to the elastic terminal. When the contact moves towards the recess, the contact is capable of pushing the contact protrusion to make the elastic terminal bend towards the bottom portion of the recess so that the free end leans against the bottom of the recess.

  • Patent number: 8318411
    Abstract: Method for fabricating an interposer is provided. A substrate is provided having thereon at least a conductive via and at least a flange. The flange is bonded on the substrate and shades a portion of the via. A photoresist layer is formed on the interior surface of the via, on a contact surface of the flange and on an inner surface of the flange opposite to the contact surface. An opening is formed in the photoresist layer to expose a portion of the contact surface of the flange, while the photoresist layer still covers the interior surface of the via and the inner surface of the flange. A plating layer is formed on the exposed contact surface of the flange. The photoresist layer is then removed.

  • Patent number: 8294042
    Abstract: A method of manufacturing a connector is provided. Firstly, a substrate having a first surface, a second surface opposite to the first surface and a through hole is provided. Next, a first conductive layer covering the inside wall of the through hole is formed on the substrate. Then, a filler is filled in the through hole to form a filler post. Next, a conductive elastic cantilever is formed over the first surface and electrically connected to the first conductive layer. Then, a gold layer is formed on the conductive elastic cantilever and over the first surface. A solder ball electrically connected to the first conductive layer is formed over the second surface.
