Backplane PCB
Backplane PCB manufacturing has been a specialized nature of the product . Back thicker than conventional PCB board and heavy , and accordingly its heat capacity is also large .Backplane PCB generally refers to larger format printed circuit boards that are used as backbones for connecting several PCBs together to ultimately form a computer bus. Typically, they do not contain active components; rather, they serve as a connection center between active duty PCBs. Backplane PCBs often incorporate a wide variety of features including blind / buried vias, high-speed / high-speed materials, backdrilling, counter bore,high aspect ratio and controlled impedance. Backplane PCB usually used a Printed Circuit Board also have been used in minicomputers and high reliability applications.
