3D MID development/prototype

Contribute to product development and prototyping with 3D MID technology

JOHNAN supports you in every step of the way - from idea/design to injection molding, patterning, plating, 3D SMT and mass production in any industry. We are here to serve customers in need of prototyping even based on an preliminary idea, download the document to learn more.


1. Features and strengths

(1) Provide development support (Propose ideas)

Are there problems with your current manufacturing that require shape changes or miniaturization? 3D MID technology is transforming industrial production by patterning conductive traces and mounting components directly on a 3D housing. As one of the world’s foremost suppliers in this field, our highly specialized and experienced technicians will provide you with strong support from development to manufacturing.

(2) Smaller, thinner and lighter

3D MID technology can effectively draw electronic circuits and mount components on 3D structure's surfaces. By replacing a 2D circuit board with a 3D MID, electronic components can be mounted not only on flat surfaces (i.e. PCB, flexible circuit board) but also curved surfaces, thus this greatly reduces the limitation of installation location. Therefore, this technique adds power to the trend towards miniaturization and lightweight.

Our proposals realize (examples):

  • ▪ the integration of "a substrate + molded pieces"
  • ▪ cost-saving by reducing assembly man-hours.
  • ▪ lightweight by reducing the number of boards and wiring.

(3)Empower new level of design freedom

3D MID allows conductive traces and components to be installed on the housing depending on the shape of the product, empowering new level of design freedom.
