4 Layer PCB

4 levels The printed circuit board, or PCB, is comprised of four layers of glass fiber. The top, bottom, VCC, and GND wire layers are present. The layers are often joined together through holes, buried gaps, and blind holes. More hidden and blind holes exist than double-sided boards. The optimal layer arrangement must be used when designing a four-layer PCB stack-up to ensure proper fabrication and impedance. Make use of the best PCB design tools to assist in creating the greatest 4-layer PCB stack-up. 

The most typical multilayer PCB stack-up being used in contemporary electronics is a four-layer PCB stack-up. As far as the basic layer thickness & layer arrangement specifications are satisfied, this layer stack-up PCB can be successfully manufactured. Just use the best PCB design tools within PCBs Designer to execute your fabricator needs rather than assuming the appropriate layer count, dielectric constant, & loss tangent to define in your PCB. The designer offers the necessary resources to build conventional rigid boards, rigid-flex boards, & multilayer board assembly with a 4-layer PCB stack-up.


The inner two layers serve as the ground and supply planes, while the top and bottom levels are the signal layers. Vias are included on 4-layer printed circuit boards as well. In circuits including RF components, the inclusion of the ground and supply layers avoids electromagnetic interference (EMI). Additionally, it minimizes the loop impedance, offers a low resistance power supply, and offers a short returning signal path.


  • More Complicated Projects – The extra layers of a 4-layer PCB will be more helpful for your project the more complicated it is. You may create the greatest finished product by expanding your creative design options, including layouts, routing, & additional components.
  • High Quality – It is a clear decision to switch from a 2-layer to either a 4-layer PCB design for even straightforward items that demand the best quality. 4-layer boards deliver a higher-quality outcome if the price is not a concern.
