Electrical Engineering

At Sparx, our engineers are engaged in a project from start to finish, which yields a high level understanding of all the details of design, test and production. Electronics are a critical component of any technology system. Manufacturability is a constant concern, and designs are optimized for ease of testing to minimize production steps.

Whether your design needs to be intrinsically safety or explosion proof for gas hazards, you’re designing electronics for aerospace, or you’re pursuing FDA 510K for a new medical device, we have the experience to get your product certified for global distribution.​

Custom Test Fixtures

Cable Harness Design

Sparx is skilled in producing designs for cable harnesses as well. Whether the cabling is internal to an enclosure or a rugged, industrial umbilical cable for harsh environments, we can design what your application needs. We can create cable drawings, assembly instructions, and bill of materials and any other documentation you require. We can source components, build prototypes, build cable test equipment and procedures, and work with contract manufacturers to turn your custom cable assembly into an orderable part number.

Our work doesn’t stop with design and manufacturing – to truly bring a product to market often means successfully achieving regulatory compliance and approval, with documented adherence to industry standards. Our on-site test equipment and test methods help us prepare for compliance testing so assure confidence in our designs before we’re at the test facilities. Similarly, we pursue field testing in real world environments to make sure that usability needs and compatibility with environmental variables are met.
