♦ What is Printed Circuit Board?

A ​​Printed Circuit Board (PCB)​​ is a flat, rigid or flexible board made of insulating material (like fiberglass or plastic) with conductive pathways (traces) etched or printed onto its surface. These pathways connect electronic components (resistors, capacitors, ICs, etc.) to form a functional circuit.

♦ Key Parts of a PCB:​

1. 1. ​​Substrate (Base Material)​​

      • Usually made of ​​FR-4​​ (fiberglass-reinforced epoxy), but can also be polyimide (for flexible PCBs) or ceramic (for high-frequency applications).
      • Provides mechanical support and insulation.

   2. ​​Copper Layer​​

      • Thin sheets of copper are laminated onto the substrate to form conductive ​​traces​​ (wires) that carry electrical signals.

   3. ​​Solder Mask​​

      • A protective layer (usually green, blue, or red) that covers the copper to prevent short circuits and oxidation.

   4. ​​Silkscreen​​

      • White or black markings (text, symbols) printed on the PCB to label components, test points, or logos.

   5. ​​Pads & Vias​​

      • ​​Pads​​: Metal areas where components are soldered.
      • ​​Vias​​: Small holes plated with copper to connect traces between different layers (in multi-layer PCBs).

♦ Types of PCBs:?​

• • ​​Single-Layer PCB​​: Simplest type, with copper traces on one side.
  • ​​Double-Layer PCB​​: Traces on both sides, connected by vias.
  • ​​Multi-Layer PCB​​: 4+ layers (common in computers, smartphones).
  • ​​Flexible PCB (FPCB)​​: Made of bendable materials (e.g., polyimide).
  • ​​Rigid-Flex PCB​​: Combines rigid and flexible sections.
