In addition to the conductive layer and the dielectric layer, the laminated structure of the PCB further includes a solder resist layer and a silk screen layer which are PCB Board Layer Composition. The solder mask covers the surface signal layer (top layer and bottom layer) of the PCB and is mainly composed of a…

Why We Need Dielectric Layer in the Printed Circuit Board Structure

PCB Board DesignBy circuitwork May 17, 2019 Leave a comment

A dielectric layer is sandwiched between every two conductive layers of the Printed circuit board, either the signal layer or the planar layer. For PCBs, the main function of the dielectric layer is support the whole pcb circuit board structure, and the main electrical function is insulation among conductive layers. First of all, since the…
