1 Copper-clad laminate is a crucial substrate material in PCB manufacturing and serves as the core material in the upstream process of PCB manufacturing. Its relationship with PCBs is highly interdependent. The primary component of a circuit board is the copper-clad laminate, which consists of a substrate, copper foil, and adhesive.
Copper-clad laminate is a material made by soaking electronic glass fibers or other reinforcing materials in resin, with one or both sides covered with copper. More importantly, it is widely used in television, radio, computers, mobile communication, and other electronic products.
The purpose of copper-clad laminate
1. Electronic communication field
Copper-clad laminate is widely used in electronic products such as mobile phones, computers, communication devices, and network devices. Among them, mobile phones are one of the most important application areas of copper-clad plates, and the quality of copper-clad laminate used in mobile phones has a significant impact on the performance and quality of mobile phones.
2. Computer field
With the development of computers, the application range of copper-clad laminate has gradually expanded and become an essential part of computer hardware. For example, copper-clad boards are widely used in hardware such as power boards, motherboards, expansion cards, and memory modules.
3. Consumer Electronics
With the increasing popularity of consumer electronics products, the application of copper-clad laminate in this field is also gradually increasing. For example, copper-clad panels are used in products such as smartwatches and smart homes.
4. Automotive Electronics
Automotive electronics is one of the future development directions, and copper-clad laminate are also widely used in the field of automotive electronics, such as in-car entertainment systems, in-car navigation systems, and body control systems.
The role of PCB copper coating
1. Improve the conductivity of the circuit board
PCB copper coating can improve the conductivity of the circuit board to ensure the electrical connection between various components on the circuit board. The high conductivity of copper foil can reduce signal loss and resistance on circuit boards. In addition, the copper coating can also be used to form a large area of grounding or power layer to reduce electromagnetic interference and circuit noise.
2. Enhance the mechanical strength and corrosion resistance of circuit boards
PCB copper coating can enhance the mechanical strength and corrosion resistance of circuit boards. The copper foil has high strength and hardness, which can protect circuit boards from external pressure and wear. In addition, the copper coating can also prevent the circuit board from being affected by oxidation and corrosion, thereby extending the service life of the circuit board.
3. Reduce electromagnetic interference on the circuit board
PCB copper coating can reduce electromagnetic interference on circuit boards. Due to the high conductivity and low resistance of copper foil, it can form a complete grounding or power layer, effectively shielding the electromagnetic interference on the circuit board. This is very important for the normal operation of some high-frequency circuits.
Copper-clad laminate, as an important basic material for circuit boards, undertakes the four major functions of PCB conductivity, insulation, support, and signal transmission.
