Abstract
An apparatus is described for a bridge clip used to hold an IC package to a process carrier in the semiconductor manufacturing processes. According to embodiments of the present invention, the bridge clip includes a bridge comprising a rectangular sheet having tabs at opposite ends the tabs having an irregular shape, a stiffener affixed to the bridge, the stiffener comprising a rectangular sheet sized to fit within the bent down tabs of the bridge and having a stiffening structure along a longitudinal axis of the stiffener, and a pressure plate coupled to the stiffener under the bridge and fitting within the tabs and long edges of the stiffener.
Claims34
A bridge clip, comprising:
- a bridge having an elongated surface with a tab at each and opposite ends for attaching to a process carrier,
- a stiffener adjacent to the bridge, the stiffener being substantially stiffer than the bridge to stiffen the bridge, wherein the stiffener is elongated and comprises rolled down edges along opposite, long sides of the stiffener;
- and
- a pressure plate adjacent to the stiffener between the tabs of the bridge to engage a surface of an integrated circuit package.
A bridge clip, comprising:
- means for engaging retention slots on a process carrier;
- means for stiffening the means for engaging, the means for stiffening being a discrete component separate from the means for engaging, wherein the means for stiffening comprises elongated rolled down edges;
- and
- means for providing a substantially constant pressure to an integrated circuit package retained in the process carrier.
A method, comprising:
- attaching a process carrier using a bridge having an elongated surface with a tab at each and opposite ends;
- stiffening the bridge using a stiffener adjacent to the bridge, the stiffener being substantially stiffer than the bridge, wherein the stiffener is elongated and comprises rolled down edges along opposite, long sides of the stiffener;
- and
- engaging a surface of an a pressure plate adjacent to the stiffener between the tabs of the bridge to engage a surface of an integrated circuit package.
