Multilayer PCB 

There is a increased demand for products using the Multilayer PCB.To reduce size of product & for betterfunctionality which depends on the interconnection between the layers that it is made up of. Without microvia production improvements, PCB manufacturers are forced to increase product size to improve performance. The increasing cost of property is driving all industries to seek smaller products, lowering the demand for end products that contain thick, high-layer count printed circuit boards.

How I stack Multilayer PCB?

For High speed design

Layer 1 ----------------------------Device and signal1

Layer 2 ----------------------------Power plane

Layer 3 ----------------------------GND plane

Layer 4 ----------------------------Signal 2

Layer 5 ----------------------------GND plane

Layer 6 ----------------------------Signal 3

Layer 7 ----------------------------Signal 4

Layer 8 ----------------------------GND plane

Layer 9 ----------------------------Signal 5

Layer 10--------------------------- GND plane

Layer 11 ---------------------------Power plane

Layer 12----------------------------Devices and signal 6
