Rigid PCBs are something you will encounter almost everywhere. Their applications range from small electrical devices to large aerospace, military, and medical fields. Next, if we talk about ‘Flexible PCBs,’ they are built of the flexible substrate as opposed to rigid PCBs and have more advantages too. They have a lower thickness, have lighter weight, are dynamically bendable, can save space, and are more accessible for 3D interconnection assembly. They also have equally broad applications because of their excellent electrical and thermal performance. The next dominant type is the ‘Flex-Rigid PCB,” built through further development and optimization of flexible PCBs. We will discuss the properties, manufacturing, and applications of Flex-rigid PCBs. But first, let us generally describe Rigid-flex PCBs.
