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.

wiring

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

straight wiring

Cracks appear

meander wiring

Cracks do not appear

vertex value R20mm was used for prototype

Example of Layer constitution

Integrally mold with resin by fitting the circuit to the three-dimensional curved surface

Stretchable biological electrodes

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.

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.

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.

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.
