Understanding PCB Components and Production Methods

• Components of a PCB: A printed circuit board (PCB) is made up of various elements including pads, vias, mounting holes, wires, connectors, filling, and electrical boundaries.
• Component Functions:
  • Pad: Metal hole for soldering component pins.
  • Mounting Hole: Secures the PCB in place.
  • Wire: Copper film for connecting component pins.
  • Connectors: Facilitate connections between circuit boards.
  • Filling: Copper coating for ground wire network, reducing impedance.
  • Electrical Boundary: Defines the size of the PCB to ensure component compatibility.

Types of PCB Layer Structures

• Single-Layer Board: Features copper on one side for wiring and soldering, with components placed on the other side.
• Double-Layer Board: Utilizes copper on both sides, top for component placement and bottom for soldering.
• Multi-Layer Board: Consists of multiple layers, including top, bottom, and intermediate layers serving various functions such as wiring, signal transmission, power distribution, and grounding.
