The manufacturing process

IMSE manufacturing has four main process steps. IMSE combine cosmetics, structure, and function into single injection-molded 3D designs, reducing assembly and integration challenges compared with conventional electronics.

  • Screen Printing IMSE manufacturing starts with printing. Decoration, if desired, is printed on film insert molding (FIM) material, followed by printing electronics including conductive circuitry, touch controls, antennas and proximity sensors.
  • Surface Mounting Electronic components are mounted using standard high-speed pick-and-place (SMT) equipment. Components are attached to the FIM substrate using conductive and structural adhesives.
  • Thermoforming Thermoforming transforms the flat electronics film into its 3D shape. TactoTek® design rules and verified material stacks maintain mechanical and electrical system integrity through the forming process.
  • Smart film insert molding The formed electronics film is used as an insert for injection molding, resulting in a single-piece structure with encapsulated electronics. Typical molding materials include high pressure, high temperature plastics such as polycarbonate and thermoplastic polyurethane (PC and TPU).
