Whether we build the product, or the product is brought to us for a second opinion, MRO Electronic Supply has the equipment and expertise to effectively test your product ensuring quality outcomes every time. As a global supplier for electronic manufacturing service, MRO builds cable assemblies, wiring harnesses and box builds for a variety of sectors.

With nearly 3 decades in the electronic manufacturing industry, we know that high quality manufacturing is no accident—it requires a dedicated, disciplined effort to produce cable assemblies, wiring harnesses, and box builds that meet and exceed our client’s expectations, industry standards, regulatory requirements, and can be relied upon in mission critical environments.

One of the most important elements in developing and manufacturing quality electronic supplies is the necessary equipment and expertise to effectively test inputs, materials and products. At MRO Electronic Supply all materials and components are inspected for quality and conformity before entering the manufacturing supply stream and every cable assembly, wiring harness and box build produced by MRO undergoes 100% testing before shipping.
