Dimation  offers a variety of flex circuit capabilities, including single or double sided circuitry to multilayer technology up to 6 layers. We also have multiple material substrates and adhesives to choose from, along with surface finishes and treatments.

Stiffeners can also be added to reinforce selective areas of the flexible circuitry for component support durability and mounting.

Types of Flex Circuits

Single-Layer Flex Circuit

IPC 6013 - Type 1

One conductive layer, either bonded between two insulating layers or uncovered on one side.

Stiffeners, pins, connectors, components, are optional.

Multi-Layer Flex Circuit

IPC 6013 - Type 3

Three or more flexible conductive layers with flexible insulating layers between each one; outer layers may have covers or exposed pads.

Plated through-holes provide connection between layers.

Controlled impedance possible.

Double-Sided Flex Circuit

IPC 6013, - Type 2

Two conductive layers with an insulating layer between; outer layers may have covers or exposed pads.

Plated through-holes provide connection between layers.

Stiffeners, pins, connectors, components are optional.

Rigid-Flex Circuit

IPC 6013 - Type 4

Two or more conductive layers with either flexible or rigid insulation material as insulators between each one; outer layers may have covers or exposed pads.

Rigid-flex has conductors on the rigid layers, which differentiates it from multi-layer circuits with stiffeners. Plated through-holes extend through both rigid and flexible layers (with the exception of blind and buried vias). Rigid-flex costs more than a standard circuit with stiffeners.
