Electronics Manufacturing Services in Mexico
Shelmex is an electronics manufacturer in Mexico that runs the full production program for your electronic product. We source the circuit boards and components, launch the program with a controlled process, assemble and test every unit, and deliver finished products, so your team works with one partner instead of a chain of suppliers.
Each program is set up around your product, your volumes, and the way you want it delivered.
One Partner From Sourcing to Delivery
Electronics manufacturing services cover the whole program, not just one step. We manage the supply chain, the launch, production, testing, and shipping, while the hands-on build is done by our electronic assembly team. You get a single point of contact and one accountable plan.

Frequently Asked Questions
How is pricing structured?
We work with an open book cost structure and a small margin on materials. When component costs go down, whether through our sourcing or yours, the savings show up in your price.
Can you build our electronics and wire harnesses together?
Yes. Because we also build wire harnesses and cable assemblies, your electronics and their wiring can be produced and checked side by side, which cuts the handoffs between suppliers.
