How it works

  1. 01

    Send your BOM or pick a catalog SKU

    Share a board requirement or a bill of materials. We qualify the build against our Indian EMS partners in Pune, Bengaluru, and Chennai and lock critical components.

  2. 02

    We quote, build, and import

    Turnkey or consigned builds to IPC Class 2. We act as the U.S. importer of record — freight, customs, and duties are our problem, not yours.

  3. 03

    Boards land in the U.S., supported here

    You buy in dollars from a U.S. company. Technical questions and NPI work go through our U.S. team, not an overseas email chain.

A Texas-facing importer, not a trading company.

We qualify the factories, lock the critical parts, and stand behind every board we import. When something goes wrong, you call a U.S. number and talk to the people who placed the build order — not a broker.
