Types of Printed Circuit BoardsTypes of Printed Circuit Boards from PCB Universe

Single Sided Board

This is the least complex of the Printed Circuit Boards, since there is only a single layer of substrate. All electrical parts and components are fixed on one side and copper traces are on the other side.

Double Sided Board

This is the most common type of board, where parts and components are attached to both sides of the substrate. In such cases, double-sided PCBs that have connecting traces on both the sides are used. Double-sided Printed Circuit Boards usually use through-hole construction for assembly of components.

Multi Layered Board

Multi layered PCB consists of several layers of substrate separated by insulation. Most common multilayer boards are:  4 layers, 6 layers, 8 layers, and 10 layers. However, the total number of layers that can be manufactured can exceed over 42 layers. These types of boards are used in extremely complex electronic circuits.
