    Compared to a printed circuit board having low layer counts, 20 layer PCB features thicker layers, thinner dielectric layers, compact via placements, etc. That’s why it requires high-class attention to achieve the optimum output of 20 layer circuit boards. There are some difficulties in manufacturing this PCB. Such as

    Layer Alignment

    Ensuring proper alignment in high-layer circuit boards like 20 layer PCB is very challenging. The alignment tolerance of the outer layer is lower than that of the inner layers of a 20 layer circuit board.

    Besides, operating temperature and humidity cause difficulties in maintaining perfect consistency in different core PCB layers. That’s why controlling the interlayer alignment in a 20 layer PCB becomes difficult for the manufacturer.

    Arrangement Of Inner Layers

    20 layer circuit boards are usually made of materials having high glass transition temperature, high dielectric strength, low relative permittivity, etc. These materials used in inner layers require top-notch design control and impedance stability.

    These requirements increase difficulties in the fabrication of the circuit board. Besides, the probability of improper placement of the inner layer has been enhanced due to high layer count designs.


    20 layer PCB materials deliver high roughness during PCB drilling. Since a high layer count increases the copper thickness of a circuit board, drilling becomes more challenging.

    Layer Coupling And Pressing

    As the number of PCB inner layers increases, the pressing difficulties simultaneously increase. Again, it makes the layer coupling problematic.

    It is required to consider thermal resistance and pressing programs when designing the laminated structure. But, the 20 layer PCB layer arrangement demands great attention to properly take care of these issues.

    These factors make the production of a 20 layer circuit board difficult. You need to choose a trusted manufacturer to take care of its manufacturing. Then, it will be easier for you to overcome these challenges.

    Which Vias Are Used In 20 Layer PCB Stackups?

    PCB vias are vital parts of PCB manufacturing. Vias have superior use in multilayer PCB designs. They ensure smooth transmission of heat in different PCB layers. Besides, PCB vias have vital impacts on current conduction and circuit board designs.

    Different types of vias are used in 20 layer PCB stackup to optimize the design, such as blind vias, buried vias, through-hole vias, etc.

    Blind Vias

    Blind vias are used in connecting an outer layer to an internal layer. These vias never go through the whole circuit board. You can see the blind vias from only one end of the 20 layer PCB.

    Buried Vias

    Buried vias are not visible from any terminal of a multilayer PCB. These vias connect two internal PCB layers. They have no connection with the external layers of printed circuit boards.

    Through-hole vias

    In this case, via holes go through the whole circuit board. That means these vias join the top and bottom layers of this 20 layer circuit board. Through-hole vias can be found in two forms. They are plated through-hole (PTH) and non plated through-hole (NPTH).

    Micro vias

    Micro vias are usually used in 20 layer HDI PCBs. These vias have a small diameter, and they are drilled by using laser technology in most cases. In a 20 layer PCB stackup, micro vias are classified into two types.

    One type of micro via is stacked via. Stacked vias are placed on one another in successive PCB layers. On the contrary, staggered micro vias have scattered positions in different layers.
