Flexible PCB, also known as flex prints or flex circuits, is a special type of
circuit board that you can bend into the desired shape. They are
widely used for high-density and high-temperature applications. The
flex designs are composed of polyimide or a transparent polyester
film as a substrate material that comes with high heat resistance
which makes it a right fit for solder mounting components.
A flexible circuit comes with a conductive layer of traces made up
of copper that is combined with a polyimide dielectric layer. The
thickness of the copper conductive layer can vary from 0.0001’’ to
0.010’’ and the thickness of the dielectric material can range from
0.0005’’ to 0.010’’. An adhesive is required to bond the conductive
copper layer to the substrate; while sometimes vapour deposition is
equally handy to attach the copper with the substrate.
The material selection for making flexible circuit boards is a bit
tricky and depends on many factors including chemical and
mechanical resistance, current, temperature, capacitance, and types
of flexing.
The flexible designs are more reliable as they come with fewer
interconnections that ensure fewer solder joints and contact
crimps. And these circuits require less space due to their flexible
bend capability and they cover only 10% of the area compared to
rigid circuit boards.
