Copper Clad PCB Board Basics

What is a Copper Clad PCB Board?

You use a copper clad PCB board as the foundation for most electronic devices. This board starts with a base material, such as fiberglass or resin, and gets covered with a thin layer of copper on one or both sides. The copper layer allows you to create pathways for electricity, which connect different parts of your circuit.

• A copper clad PCB board is a base material that is typically made from FR4 (fiberglass), CEM-1, or phenolic resin.

• It is laminated with a thin layer of copper on one or both sides.

You find copper pcb boards in almost every electronic product, from smartphones to industrial machines. The copper layer provides excellent electrical conductivity, which is essential for reliable circuit operation. When you design a pcb, you choose the right copper clad laminate to match your application's needs. LT CIRCUIT uses advanced copper clad laminates to ensure high performance and reliability in all their products.

Copper PCB Board Structure

A copper pcb board contains several layers, each with a specific function. Understanding these layers helps you see how the board supports complex circuits and applications.

The copper layer forms the main pathways for your circuit. The solder mask layer protects these pathways during pcb fabrication and assembly. The pad layer allows you to attach components securely. When you use a double sided copper pcb board, you get copper layers on both sides, which increases the complexity and capability of your circuit boards.

The thickness of the copper layer plays a big role in how your copper pcb board performs:

• Improved current handling: Thicker copper layers reduce resistance, allowing more current to flow efficiently.

• Enhanced thermal management: More copper helps spread heat, keeping your components safe.

• Reduced voltage drop: Thicker copper keeps voltage steady across the circuit.

• Better signal integrity: Thicker copper reduces signal loss, which is important for high-speed or RF applications.

• Mechanical durability: More copper makes the board stronger and more resistant to damage.

Industry standards like IPC-2221 and IPC-2152 guide you in choosing the right copper thickness for your pcb design.

LT CIRCUIT uses Panasonic’s high-performance copper clad laminates, which offer tight control over dielectric properties and thermal stability. These features make LT CIRCUIT’s copper pcb boards ideal for demanding applications, such as 5G networks and automotive electronics.
