Mechanical & Electronics Engineering

Mechanical and electronic design handled by the same team, so the structure of a charging mount and the circuit inside it are not solved in isolation.

Stage 02 of 6 Concept → Mass Production
Overview

In products that combine molded structure with electronics, most failures sit at the boundary — thermal behavior, tolerance stack, connector strain, assembly sequence. Keeping both disciplines in one team is how those problems get found early.

A wireless charging car mount is the clearest example. The coil has to sit within tolerance of where the phone will actually rest, which depends on the clamp geometry and how the molded housing shrinks. The heat the coil generates has to leave through a plastic body that was chosen for finish and impact resistance. The clamp arm moves, so the cable route inside it flexes for the life of the product. Each of those is a mechanical decision and an electronic decision at once, and they are cheap to resolve now and expensive to resolve after the tool is cut.

COMART holds an Apple MFi license in its own name, so products requiring MFi are developed under our license rather than routed through a third party's.

We act as the single window for electronics: specification, supplier selection, schedule and quality with our external PCB, PCBA and certification partners. Not every electronic process is performed inside our own plants, and we say so plainly rather than presenting partner capacity as ours.

What this stage covers

  • Mechanical designStructure, tolerance, assembly sequence and serviceability, designed for the molding process that will make it.
  • Material & structure selectionMaterial choice matched to load, finish, regulatory needs and process window.
  • Moving-part and mechanism designClamp arms, ball joints, hinges and spring elements engineered for the cycle count the product will actually see.
  • Electronic system planningSystem architecture, power, thermal path, and the split between in-house and partner scope.
  • Circuit designSchematic and layout developed against the mechanical envelope, not after it.
  • Firmware developmentControl, communication and behavior, including the test modes needed on the production line.
  • Test planningWhat gets tested, at which stage, and to which criteria — defined before the first tool is cut.
  • PCB, PCBA & certification partnersExternal resources managed by COMART as a single window: specification, quotation, schedule and quality.

Bring us the mechanical problem and the electronic one together.

If your product has a coil, a cable or a circuit inside a molded body, the two sides are one problem. Tell us what it has to do.
