Stack-up refers to the arrangement of copper and insulating layers that make up a PCB prior to board layout design. For multilayer PCB, general layers include ground plane (GND plane), power plane (PWR plane), and inner signal layers,which describes the basic construction of a PCB. Specifically, the stack-up defines the total number of PCB layers and the type of each of these layers.
A good stack-up can be very effective in reducing radiation from the loops on the PCB (differential-mode emission), as well as the cables attached to the board (common-mode emission).PCB stack-up is an important factor in determining the EMC performance of a product. A good stack-up can be very effective in reducing radiation from the loops on the PCB (differential-mode emission), as well as the cables attached to the board (common-mode emission). On the other hand, a poor stack-up can increase the radiation from both of these mechanisms considerably.
2)The number and types of planes
3)The sequence of the layers
4)The spacing between the layers.
PCBAstore will help you to get proper stack-up to achieve your best PCB performance and lower your PCB cost. PCBASTORE will Provide you standard stack-up available for Multilayer PCB for your reference.
