2 layer flex pcb stackup

The top layer is typically a copper layer that serves as the signal layer,

while the bottom layer is usually a ground plane or power plane.

The adhesive layer provides insulation and bonding between the two layers.

The thickness of the flexible material and the adhesive layer can vary depending on the specific requirements of the application.

The thickness of the copper layer is typically around 1 oz, or 35 microns.

In addition to the two layers, a coverlay or solder mask layer may be added to protect the copper traces and provide insulation.

A stiffener may also be added to provide support and stability to the flexible PCB.
