Scrabble?! INTERPOSERS

Definitions of INTERPOSERS in various dictionaries:

An interposer is an electrical interface routing between one socket or connection to another. The purpose of an interposer is to spread a connection to a wider pitch or to reroute a connection to a different connection.Interposer comes from the Latin word "interpōnere", meaning "to put up between".A common example of an interposer is an integrated circuit die to BGA, such as in the Pentium II. This is done through various substrates, both rigid and flexible, most commonly FR4 for rigid, and polyimide for flexible. Silicon and glass are also evaluated as an integration method. Interposer stacks are also a widely accepted, cost-effective alternative to 3D ICs. There are already several products with interposer technology in the market, notably the AMD Fiji/Fury GPU, and the Xilinx Virtex-7 FPGA. In 2016, CEA Leti demonstrated their second generation 3D-NoC technology which combines small dies (“chiplets”), fabricated at the FDSOI 28 nm node, on a 65 nm CMOS interposer.Another example of an interposer would be the adapter used to plug a SATA drive into a SAS backplane with redundant ports. While SATA drives can be connected to nearly all SAS backplanes without adapters, an interposer would allow providing path redundancy.
