Answers

Bridge Manufacturing questions.

What is Micromex Bridge Manufacturing?

A way to produce in Mexico where Micromex owns the plant, the people, the permits, quality and management — while you stay as involved as you want to be.

Most ways to build in Mexico make you choose between control and convenience. A shelter or a campus gives you control but leaves you running a plant and carrying the headcount. A contract manufacturer is fast and hands-off but works like a sealed box. Bridge connects the two: we own and run everything, your engineers can be on our floor or on a call, and material can be consigned or turnkey.

How is Bridge Manufacturing different from contract manufacturing?

Nothing is sealed. You get the speed and zero headcount of contract manufacturing, plus full visibility and as much control as you want.

With a typical contract manufacturer you send a print and a purchase order and product shows up. You rarely see inside, problems surface when the truck arrives, and changes mean renegotiating. With Bridge, your engineers are welcome on our floor, you see the line, your supply chain can stay yours, and we adjust the program together as you go.

How is Bridge Manufacturing different from a shelter?

With a shelter you still run the plant and pay for the headcount, including layoff costs. With Bridge, Micromex carries both.

A shelter company handles the legal entity, payroll paperwork and customs, and provides the building, which it owns or rents and passes the cost on to you. The shelter is the legal employer, but every employee cost is yours, and if you lay people off, the severance and unemployment costs are passed to you. You still buy the equipment, choose the staff and manage the floor, which typically takes 12 to 18 months to stand up. Bridge keeps the involvement and visibility of a shelter without the capital, the headcount or the wait.

Who employs the workers?

Micromex does. Every person on your line is a Micromex employee.

We recruit, hire, train and pay the team, provide benefits and Mexican social security (IMSS), and manage turnover and retention. You never have employees in Mexico on your books.

Who carries the employment liability?

Micromex. Employment obligations under Mexican labor law stay with us and are never passed on to you.

Labor-law compliance, severance and staffing changes when volumes go up or down are our responsibility as the employer. You get a stable, trained team without the legal and financial exposure of employing people in another country.

What happens if our volumes change?

We plan staffing changes with you, and the hiring, retraining and severance that come with them stay on our side.

Because Micromex is the employer, ramping up or scaling down never becomes a hiring drive or a layoff on your books. Tell us your forecast and we’ll staff the line to match.

Can our engineers work on the Micromex floor?

Yes. Your engineers can be on our floor or on a call — as involved as you want.

Visibility is the point of Bridge. Visit any time, station your own engineers or quality staff with the line, or check in remotely. Our Tucson team is on Arizona time and a short drive from the plant.

What’s the difference between consigned and turnkey material?

Consigned means you own and supply the material. Turnkey means Micromex sources and manages it.

You can keep your current supply chain and consign material to us, let us buy and manage everything, or mix the two by part. Under IMMEX, imported material for export production has its duties deferred either way.

What does Micromex build?

Wire harnesses and cable assemblies, electrical and electromechanical assemblies, transformers, specialty packaging and kitting, plus remanufacturing.

Builds range from low-volume prototypes to full production runs. We also run sub-assembly builds that drop straight into your line, retail-ready packaging and multi-component kits. Many programs start as a problem another supplier declined to solve.
