发明名称 Plastic land grid array (PLGA) module with inverted hybrid land grid array (LGA) interposer
摘要 An enhanced contact construction and loading support mechanism for plastic land grid array (PLGA) modules. A plurality of inverted hybrid land grid array (LGA) contacts are each respectively captured in and extend at least partially through one of a plurality of holes of an inverted hybrid LGA interposer. The inverted hybrid LGA contacts are affixed to a plurality of metal pads on a PLGA module carrier. Preferably, the inverted hybrid LGA contacts are affixed simultaneously using surface-mount technology (SMT) and have a metallurgy construction (e.g., beryllium-copper springs coated with nickel and hard gold) that provides enhanced wear and corrosion resistance. Each of the inverted hybrid LGA contacts is configured to make mechanical/pressure contact with a metal contact on another substrate, such as a printed wiring board (PWB). The inverted hybrid LGA interposer supports the PLGA module carrier and, in addition, a stiffener frame (with or without a heat sink) may be provided to reinforce the PLGA module carrier.
