Our services

From prototype to production

Whatever you need built, Pecko can take it from the first engineering review to volume production, and further up the assembly when it helps.

  • Prototyping and NPI

    Engineering review, prototype builds and new product introduction, so a design is proven before volume production starts.

    Prototype services

  • Box build and system integration

    Harnesses, cables and sub-assemblies integrated into finished enclosures and systems, wired and tested to your documentation.

    Box build

  • OEM and contract manufacturing

    Production built to your drawings and specifications, from first articles to volume across our factories in Singapore, Malaysia and China.
