What is PCB Fabrication? A Complete Overview You Should Know

A Printed Circuit Board (PCB) is the backbone of electronic circuits, while PCB fabrication is the process of producing that circuit board. In this article, we will explore in detail what PCB fabrication is, its applications, and the PCB manufacturing process at KZ TECH Vietnam Joint Stock Company.

1. What is PCB Fabrication?

PCB fabrication (Printed Circuit Board fabrication) is the process of manufacturing electronic circuit boards used to connect and secure components such as resistors, capacitors, ICs, transistors, and other electronic parts on a board.

PCBs play a vital role in almost every electronic device, ensuring that circuits operate correctly and remain stable over time.

PCB fabrication is typically carried out based on PCB design files (Gerber files) and specific technical requirements provided by customers.

The information above provides a basic understanding of PCB fabrication. Below are some key insights into PCB classifications, manufacturing processes, and current trends that you should not miss.

2. How is PCB Fabrication Classified?

PCB fabrication can be classified in several ways depending on structure and application requirements.

2.1 Single-Layer PCB Fabrication

Single-layer PCB fabrication refers to the production of a circuit board with only one conductive copper layer. All circuit traces are located on one side of the PCB, while the other side serves only as an insulating base.

Characteristics of Single-Layer PCBs

• Only one side contains copper traces

• Components are usually through-hole (DIP) mounted

• Simple circuit design and easy maintenance

• Lowest cost among PCB types

Applications of Single-Layer PCBs

Single-layer PCBs are commonly used in:

• Simple control boards

• Linear power supply circuits

• Relay and contactor control circuits

• Basic industrial electrical equipment

• Circuits inside electrical cabinets, hoists, or lifting equipment (auxiliary circuits)

They are ideal for simple circuits with fewer components and low-density layouts.

2.2 Double-Layer PCB Fabrication

Double-layer PCB fabrication involves manufacturing circuit boards with two copper layers on both sides (top and bottom). These layers are connected through plated through-holes (vias).

This is currently the most common type of PCB used in industrial and consumer electronics.

Characteristics of Double-Layer PCBs

• Circuit traces on both sides of the board

• Plated through-holes (PTH / vias) connect the two layers

• More flexible routing than single-layer PCBs

• Supports both through-hole (DIP) and surface-mount (SMD) components

• More compact and better organized layouts

Applications of Double-Layer PCBs

Double-layer PCBs are widely used in:

• Electrical cabinet control boards

• Hoist and lifting system controllers

• Switching power supplies

• PLC control boards and intermediate relays

• Industrial electronics and automation equipment

They are suitable for circuits with many components and higher stability requirements.

3. Multilayer PCB Fabrication

Multilayer PCBs are used for complex circuits requiring high signal performance.

They are commonly applied in industrial systems, telecommunications equipment, and smart devices.

Typical configurations include:

• 4-layer PCB (most common)

• 6, 8, 10, or 12-layer PCBs depending on design requirements

A typical multilayer PCB structure includes:

• Outer layers: signal layers

• Inner layers: power (Power), ground (GND), or signal layers
