Insert Molding with Film Electrode

「IME」New Technology of NISSHA

IMEの紹介

IME(In–Mold-Electronics)
is technology to integrate film electrode with electrical function onto plastic part, and is a new method of MID technology that can form electrodes in a 3D shaped resin.

Conventionally methods such as the LDS using a particular resin which forms the wiring by plating, and the method of bonding FPC and film electrodes using an adhesive, have been used.

Nissha IME integrate plastic part and FPC and film electrode by insert molding.

It is a technology that realizes designs that has been difficult with conventional technology and can be applied to more products and applications.

Process of NISSHA IME

The process of insert molding electrode film and FPC with NISSHA IME is very simple.
Electrode film and FPC are inserted at the same time as resin molding of housing parts such as product panels.
In addition, metallic pins or FPC connectors for taking out electrodes are also molded at the same time.
Although it is a simple process, it can handle various structural designs.
The molding know-how that NISSHA has cultivated so far is utilized for this technology.

Comparison of conventional method and NISSHA IME

In order to form electrodes and circuits on curved and uneven molded resin, the LDS method,
which is one of the MID technologies, and the method of attaching the electrode film and FPC using an adhesive such as double-sided tape have been used.
However, both methods have some weaknesses.
For example, there are problems such as restrictions on the shapes and electrode patterns that can be handled,
and increased labor and cost.
NISSHA IME solves these problems and is a technology that can be applied to a wider range of products.

LDS method…

  • Cannot support fine wiring and multi-layer circuits
  • Not applicable to large size products
  • Need to use a particuler resin
  • Transparent resin cannot be used
  • Limitations on how to connect to PCBs

Double-sided tape attaching…

  • Difficulty in environmental reliability such as vibration and temperature / humidity
  • Cannot handle shapes with irregularities and ribs / bosses
  • Increased product thickness with double-sided tape
  • Difficult to attach to small parts, it takes time and effort
  • Limitations on how to connect to PCBs

Combination with various designs

NISSHA IME can integrate not only functional electrodes.
By insert-molding a wide variety of design films at the same time, it is possible to achieve a highly designed appearance.
In addition, since transparent resin can be used,
it is possible to realize a Hidden-lit design that makes display part stand out beautifully.
Additionally, it is possible to add functions that match the customer’s product application,
such as adding a tactile sensation and giving the surface an antibacterial function.
