Electro-mechanical assembly - Complex PCB mounted board with surface mount electronic parts


TJM can create a complete assembly for use in aerospace & defense, medical, industrial, and commercial applications by incorporating mechanical power components. Electro-mechanical assemblies are often used in power supplies, elevator controls, military weapon systems, and other applications where a mechanical component needs to perform a complex electronic function. Offering cable harness assembly to provide signal and power pathways and complete product assembly (box builds), TJM is your one-stop shop from PCB assembly to your finished product.









TJM Electronics offers full system integration in box build enclosures. Box builds include sourcing and installing cables and sub-assembly components and then putting the whole package together in a customized enclosure.

This includes the installation of PCBA’s, AC & DC power units, digital interfaces, audio/video, insulation displacement, and other complex electrical systems and routing cable and wire harness assemblies into a single box build enclosure. We will work with you to get your specific requirements to create a tailor-made electro-mechanical assembly that includes all the crucial components for your design.
