What is Fibre Exposure
Fibre exposure refers to the presence of exposed board fibers after the de-paneling process in the PCB assembly. During the de-paneling process, which involves separating individual PCBs from a larger panel, it is possible for the board fibers to become exposed. These fibers are typically part of the laminate material used in the construction of the PCB. The presence of exposed fibers can be a concern as it may affect the overall quality and reliability of the PCB assembly.
