Why Do You Need Printed Circuit Board?
In today’s modern era of mobile technology, miniaturization is a must. Following this, a printed circuit board was necessitated by technocrats. It is small, thin, flexible, and lightweight, and has high wiring density. It is three-dimensionally wired and can be reshaped to fit into available space. What is Printed Circuit Board, and How is its Circuitry Made? A printed circuit board is made up of a flex board. A copper foil is laminated to a resin substrate the layers and joined with adhesive or with the application of pressure and heat into an integral board. There can be more than one conductive layer for making circuitry on either side. There are encapsulating layers, adhesive layers, and insulating layers between the conductive layers to have sufficient insulation. The plastic substrate of flexible printed circuit boards is made up of polyimide or similar thermoplastic material, such as polyacrylamide. Then, the substrate is coated with an adhesive and...
