Durability and reliability are what you look for in flex circuits. At Uni-Flex Circuits, Inc. of San Jose, California, we provide customers with the highest quality products possible. We design and manufacture single-sided flex circuits, rigid flex circuits, and several others in between. Rely on us for the interconnect solutions you require.
Flex circuits have found their way into a myriad of applications, spanning many markets, including computer, data communications, consumer medical, military, and aerospace. Common applications include:
With the inherent advantage of being lightweight, flexible, bendable, and reliable, interconnect solutions become governed by volume as opposed to space of a 2-dimensional hard board. Flex circuits are designed to accommodate surface mount, chip-on-flex, as well as flip-chip technology. The following are common types of flex circuit constructions.
Single-Sided Construction - This flex circuit features single layer construction with a polyimide cover film laminated to copper, allowing access from one side only.
Double-Sided Construction - Like its name suggests, this flex circuit consists of double-sided copper clad material with top and bottom cover films. The cover films are pre-routed to access copper from both sides using plated thru-holes.
Dual Access - This option features the same construction as the single-sided flex circuit; however, pre-routed openings are made in the cover film, allowing access to both sides of the copper layer.
Multi-Layer - The multi-layer flex circuit consists of multiple layers of single- and/or double-sided material laminated with thermoset adhesive. Layers range from 3 to 10 layers.
Wimpy - This option consists of a single-sided flex circuit with copper foil and relieved in certain areas to achieve maximum flexibility — especially in the dynamic region. This will have double-sided construction in certain areas and single-sided construction in the dynamic area.
Multi-Layered Flex Rigid - This flex circuit is a combination of single- and/or double-sided flex, laminated with thermoset adhesive onto a single- and/or double-sided FR-4 clad material. It has 1 to 8 layers in the flex area and up to 10 layers in the rigid area.
