What is Printed Circuit Board Layer Stack?
PCB layer Stackup (layer stack-up) is the arranging of signal and power layers of a PCB to meet the electrical and mechanical performance. The planning of multilayer PCB layer stackup is one of the most important factors in achieving the best performance of your product.

A good stack-up can be very effective in reducing radiation from the loops on the PCB. On the other hand, a poor stack-up can increase from both of these mechanisms considerably.

Why is PCB layer stackup an important factor?
8 Layer PCB Stackup example
PCB layer stackup is a way to getting multiple printed circuit boards in the same device by stacking them on top of each other while making sure there is a predefined mutual connection among them.
- Planning optimal multilayer layer stack-up is one of the most important factors in determining the EMC (Electromagnetic Compatibility) performance of a product. For example, to improve the EMC performance of a 4 layer board , it is better to space the signal layers as close to the planes as possible, and use a large core between the power and ground plane. This is the most effective way to improve the performance of a 4 layer board.
- A good multilayer PCB layer stackup can balance Signal Integrity (SI) well against manufacturability and reliability.
- Layer Stackup is the basic process to avoid emission, crosstalk and all other kinds of disturbances of high-speed applications.

There is really no limit to the number of layers that can be fabricated in a multilayer PCB, and Venture’s maximum capability is 32 layers.
