Single sided FlexiblePCB

This is the simplest flexible PCB type with only one conductive layer. A thin flexible dielectric film, such as Polyimide, is used. There is only one conductive layer on the board.

Double sided Flexible PCB

Double-sided flexible PCBs have two conductive layers, one on each surface. You have components or conductive lines on both sides. These flexible circuits are more economical compared to single-sided flexible PCBs.

Multilayer Flexible PCB

In a multilayer flexible PCB, there are multiple conductive layers of copper. It has at least three copper/conductive layers or more. There is a thin layer of PI between two conductive layers. These layers are interconnected with the help of vias.

Double access or back bared Flexible PCB

Dual access or back bare flexible PCB is a particular type of single-sided flexible circuit. There is only one layer of copper, but it is arranged in a special manner to be accessed from both sides. This is the specialty of a dual-access flexible circuit.

Polymer Thick Film Flexible PCB

Polymer Thick Film (PTF) flexible circuits are real printed circuits. Several types of conductive inks are used to print the circuit on the base. Most of the time, the ink is applied with the help of stencils. Most of the time, the ink is applied with the help of stencils.
