IME (In-Mold Electronics)

IME (In-Mold Electronics) is a technology for integral molding to form three-dimensional molded film which electronic circuit was drawn on and resin. By integrating parts that had been divided into the housing and electronic board, the following effects can be expected.

  • Gross weight reduction
  • Improve the performance of touch sensors, antennas, etc.
  • Improve the quality of design, reduce assembling proress
  • Protect circuits
  • Reduce cost
Our P-Flex makes multi-layerization possible not only for using PET substrate but through the process such as vacuum forming with meander copper wiring. These 3D shaped films use the process of the film of insert molding and such and enable the electronic substrate to integrate into the resin part.

In use case of straight wiring, it will be cut if it makes three dimensions, but meander wiring will prevent this disconnection.

Although the materials of the flexible PCB aren’t expandable, we have succeeded in realizing a stretchable PCB by combining laser cutters and papercutting (kirie) techniques.

Expandable circuit board that makes use of a kirigami structure

We would like to show you an expandable yet robust flexible PCB that makes use of a milkyway-like origami structure. Conventional fleble PCBs aren’t expandable.

How the non-stretchable flexible PCB can stretch

Our solution is a stretchable circuit board that uses a Tomoe-type structure.
Although the materials of the flex PCB do not stretch, it is possible to stretch a circuit board by giving it a Tomoe-type structure.

Tomoe type kirigami structure that allows for 180˚ bends

By adding these N shaped Tomoe type cutlines, no fold marks are added (to the wiring parts), greatly reducing the risk of disconnection and allowing for 180˚ bends.
