The Versatility of Flex Circuits

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:

  • Inkjet Printers
  • Hard Disk Drives
  • Laptop Computers
  • Optical Storage Drives
  • Smartphones
  • Tablets
  • Auto-Focus Cameras
  • Portable CD Players
  • Finger Oximeters
  • GPS
  • Flat Panel Displays
  • Military Equipment and many more

Designed to Accommodate Various Technologies

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.
