Murrietta Circuits offers custom designed interposer and adapter solutions for a wide range of
applications. They are most used as an interface to adapt obsolete components to a legacy circuit board
that cannot be redesigned or is impractical to redesign. By developing a customized adapter or
interposer board to “translate,” the circuit functions from one or more IC’s to the
legacy application and package footprint. In addition, this allows the customer to add features
& functions not contained in the original design by incorporating them onto the new adapter or
interposer board.
Interposers are substrates that are used to attach components as an intermediate step to directly attaching to the main/motherboard. The interposer then becomes the new package for attaching onto the circuit board. This substrate can be made from a wide range of materials, including FR4, Polyimide, Rogers, and Megtron.
