Flexible Circuits

UNIFLEX TECH , designs & manufacture Flexible Printed Circuit Board (FPC) with competitive force within the FPC industry that provides first-class technology, quality products and outstanding services. Our R&D team possesses exceptional technological capabilities coupled with automation in mass production equipment, high precision process and further advancement in Multi-layered FPC. Uniflex gives a high priority to quality control and utilized Total Quality Management to improve product quality demand.

Single-sided FPC

Basic flexible printed circuit board, composite of one layer of copper foil. This provides greater flexibility. In addition, it is lightweight, thin and space saving.

Double-sided FPC

Uses double-sided copper foil to provides greater flexibility, accommodates higher density wiring compared with single-sided FPC.

Double access

Has the same construction as single sided copper foil but opening at cover layer provides access to both sides of the copper layer.

Multi-Layer FPC

A combination of single and/or double-sided flex circuits laminated with thermoset adhesive. Provides flexibility for complex wiring accommodated in limited space.
