Types of Circuit Boards: Single Panel, Double-Sided Board, and Multilayer Board

1. Single Panel:

• Basic and cost-effective PCB with wiring on one side only.
• Not suitable for complex products due to single-sided wiring.

2. Double-Sided Board:

• Contains copper wiring on both sides connected through holes.
• Used when single-layer circuits are insufficient for electronic products.

3. Multilayer Board:

• Consists of more than three layers of conductive patterns with insulation materials between them.
• Developed for high-speed, multifunctional, and compact electronic devices.

Types of Circuit Boards Based on Characteristics:

1. Flexible Circuit Boards (FPC):

2. Rigid Circuit Boards (PCB):

3. Rigid-Flexible Junction Circuit Boards (FPCB):

Main Differences:

• Single Panel: One layer of wires, no copper in holes.
• Double-Sided Board: Wires on both sides, copper inside holes.

The key distinction is in the wiring quantity.
