Who Manufactures PCBs

Printed Circuit Boards (PCBs) are the foundation of modern electronics. From smartphones to aerospace systems, they enable electrical connections and mechanical support in compact formats. As demand for electronics grows, finding reliable PCB manufacturers becomes increasingly vital for businesses and engineers. This article explores who manufactures PCBs globally and in China, with a spotlight on Wintech, a leader in advanced PCB manufacturing and rapid prototyping.

What Is a PCB?

A Printed Circuit Board (PCB) is a board used to physically support and electrically connect electronic components. It uses conductive pathways etched from copper sheets laminated onto a non-conductive substrate.

Common PCB Uses:

Consumer electronics (phones, tablets, TVs)
Automotive (engine control, infotainment)
Medical devices (imaging equipment, diagnostics)
Industrial machinery (robotics, control systems)
Aerospace and defense (radars, avionics)

Types of PCBs Manufactured Today

1. Single-layer PCB

One copper layer, suitable for basic electronics like toys and calculators.

2. Double-layer PCB

Two copper layers with vias to connect both sides; used in HVAC systems and power supplies.

3. Multilayer PCB

More than two copper layers; used in advanced devices like smartphones and aerospace systems.

4. Rigid PCB

Solid, non-flexible base; most common in consumer electronics.

5. Flexible PCB (FPC)

Made of flexible materials like polyimide; used in wearables and foldable devices.

6. Rigid-Flex PCB

Combines rigid and flexible layers; ideal for compact, high-performance electronics.

7. HDI PCB (High-Density Interconnect)

Smaller traces, microvias, and higher wiring density; ideal for compact, high-speed electronics.

How PCBs Are Manufactured

The PCB manufacturing process requires precise steps and stringent quality control. Major stages include:

Design and layout: Engineers create circuit schematics and layout with CAD software
Printing inner layers: Copper is laminated and etched to form traces
Lamination: Layers are pressed together into a single board
Drilling: Precision holes are drilled for through-hole or via connections
Plating and etching: Depositing copper into drilled holes
Solder mask and silkscreen: Protective coating and labeling
Testing and inspection: Includes electrical testing, AOI, and X-ray inspection
