Introduction to Multilayer Circuit Boards (2-8 layers)

2-Layer PCB A 2-layer PCB consists of two layers of conductive material separated by an insulating layer. The top and bottom layers are typically used for routing electrical signals. These PCBs are relatively simple and cost-effective, making them suitable for many basic electronic devices. They are often used in applications where space is limited and the complexity of the circuit is not too high. For example, small consumer electronics like calculators and basic LED flashlights may use 2-layer PCBs.
