Fine patterns on curved surfaces

Do you have any struggles with circuit petterning on curved surfaces?

Pattering fine lines directly on curved surfaces brings a variation of benefits such as weight reduction of products and more sofisticated interface designs. The new material and the process expands the range of applications where conventional silver paste prinitng cannot reach.

New process features

Conventional process New process
Resistance value increase rate High Low
Fine paterning Good Great
Cracks Sometimes Yes No
Samples

The new process can solve the issues.

Comparison between the conventional process and the new process

Conventional process New process
Line width 100um~ 10um~
Thickness approx. 10μm〜 approx. 1μm〜2μm
Resistance value rise rate
(at 189% extension)
999.80% 104.70%
Deterioration of patterns
(at an extension)

Material : Ag

Material : Cu

Manufacturing Process

The patterned electrode film is inserted into the mold and the molten resin is injected into it.
The process makes it possible to create patterns on deep and sharp convex or concave surfaces.

Benefits of the new technology

Patterns on curved surfaces

Patterns entirely or partially cover deep and sharp concave or convex surfaces.

Smaller and lighter

Removing separate printed circuit boards enables smaller and lighter products.

Various interactive interface designs

Space saving and freedom of product designs.

A variety of plastic resin selections

A variety of plastic resins such as PC, ABS, and PC-ABS can be used.

High-density patterns

High density of fine lines.

"Dead-front"

A conbination of new technology and transparent plastic resins enables dead-front designs.
