Microelectronics

Solutions for Your Marketplace

The Plexus microelectronics (µE) team provides solutions that enable you to meet the needs of your marketplace. When the market demands higher performance (speed, weight, signal integrity) in smaller spaces, µE packaging can be the solution. Plexus offers a complete solution for your manufacturing needs, starting with custom semiconductor packaging that can be combined with surface mount circuit card assemblies and then system level integration and test.

Each customer is assigned to a project manager, who facilitates all deliverables for the duration of the project. The µE team provides semiconductor packaging at all stages of the product lifecycle: from proof-of-concept builds through pilot launch and into production volumes. Annual volumes for our customers’ products range from hundreds to tens of thousands.
