Flexible PCB manufacturing

A flexible PCB is a patterned arrangement of printed circuit and components that makes use of flexible base material with or without flexible cover layer. The flexible electronic assemblies can be fabricated with the same components as the rigid printed circuit board, however, allowing the board to meet the demands of necessary shapes during its applications.
