Sechan Electronics · Lititz, Pennsylvania

We build the electronics inside America’s defense systems, from circuit card to fielded system.

100% employee owned and building for the Department of Defense and its prime contractors since 1985.

  1. Circuit card assembly

    Three SMT lines with automated optical and X-ray inspection, building and inspecting every card to IPC-A-610 Class 3.

  2. Wire harness and integration

    Harnesses built to IPC/WHMA-A-620 Class 3 and integrated into complete units, up to shipboard missile launch canisters.

  3. Test

    Automated acceptance testing, environmental stress screening and EMI/EMC testing in our own labs before anything ships.
