MPI - Probecards - Substrate

Substrates are the key components of probe card to connect the signal between PCB and the needles. To provide highly consistent probe card, MPI design and fabricate a wide range of both MLO and MLC substrates in-house. MLO is the choice for high electrical performance while MLC is classic for precise alignment. To extend and achieve multi-DUT testing, your packaged substrate can be turned into MLOC by our patented technology.

Key features:

- MPI in-house fabrication

- Various substrate options depend on requirement

- Customized design for each specification

- Up to 4 DUTs for MLOC using packaged substrate

- Exact C4 side positioning
