Microinterconnect Solutions

Flexible Circuits

Display applications are increasing in functionality while IC driver size is shrinking. 3M's leading-edge technology enables reliable Chip on Flex interconnection of the driver IC to 3M™ Flexible Circuits, as well as interconnection to the display glass and a printed circuit board. 3M circuits can be folded flat, saving valuable space. 3M's plants in Singapore and the US ensure a multiple source of supply. 3M is also exploring custom circuit designs for hinge, camera and antenna applications.

Demo and Sample Requests

3M™ Flexible Circuits are ideal for LCD-TFT and LCD module COF applications used in computers (notebook displays and desktop monitors), consumer products (mobile phones, PDAs, and gaming devices), TFT & plasma TV, automotive and aircraft cockpit displays.

With a bend radius of 180 degrees, ultra-thin 3M™ Flexible Circuits can fit into your small device configurations, helping reduce both product size and weight.
