Successfully incorporating your concept, by producing a quality product with workmanship.


First step is to upload your BOM file. We will then search for the right components to match the required specifications  and prepare a detail estimate including labor.


To ensure quality, our designers will communicate with your engineering team for additional revisions and new designs. Throughout the entire project we report back with progress reports, photos, videos and timing updates.


To meet agreed specifications, we test for Cirrus signature-proper termination and cross wiring and short circuits. All test documentation is included with all shipped products.
