Product Description
What Is a Single-Sided Flexible PCB?
The most basic kind of flexible circuit is a single-sided flexible PCB, also known as a single-sided Flex PCВ.
They're made up of a lightweight dielectric film that's been laminated to a single copper layer.
After that, the copper coating is chemically engraved to fit the circuit pattern style.
For improved insulation and safety, polyimide cover layers may be added to the circuit board.
A single-sided flexible PCB is the type of circuit board that consists of a flexible polyimide film laminated to a thin sheet of copper.
This Circuit is also known as single-layer flex.
Then The copper layer is chemically etched to produce a circuit pattern specific to your specific design requirements.
In this circuit, Polyimide coverlay is added for insulation and environmental protection of this circuit.
One conductive copper layer and bonded between two insulating layers of polyimide coverlay/copper/flex core is added in this layer.
Flex Core Materials are:
** Standard thicknesses: ½ mil to 3 mils in either adhesive or adhesiveness constructions.
** Standard copper thicknesses:1/3 oz to 2 oz in rolled annealed or electrodeposited formats.
Its Coverlays Standard thickness is1/2 mil to 2 mil polyimide, with 1/2 mil to 2 mil epoxy or acrylic adhesive.
