How do thick copper circuit board suppliers follow strict design specifications to ensure quality?
Suppliers of thick copper circuit boards need to follow a number of design specifications to ensure that the boards supplied meet industry standards and customer requirements. The following are some of the design specifications that need to be followed:
- Size and shape of circuit boards: Thick copper circuit board suppliers need to design the size and shape of circuit boards according to the specifications and requirements provided by customers. Generally speaking, the size of the circuit board should be designed according to its use and function, and also need to consider the ease of installation and use of the circuit board.
- Thickness of the circuit board: Thick copper circuit board suppliers need to design the thickness of the circuit board according to the thickness required by the customer. The thickness of the circuit board should be designed according to its carrying current, voltage, mechanical strength and other factors to ensure that the circuit board will not be overheating, deformation and other problems in the process of use.
- Circuit board material: thick copper circuit board suppliers need to choose the right material to manufacture circuit boards. Commonly used circuit board materials include FR4, CEM-1, aluminum substrate, etc. Different materials have different electrical and mechanical properties, and need to be selected according to the specific application scenarios.
- Conductor width and spacing: Thick copper circuit board suppliers need to design the conductor width and spacing according to customer requirements. The wire width and spacing should be designed according to the current, voltage and other factors to ensure that the circuit board will not be used in the process of overheating, short circuit and other problems.
- Surface treatment: thick copper circuit board suppliers need to treat the surface of the circuit board to enhance its corrosion resistance, conductivity and other functions. Commonly used surface treatment includes gold plating, silver plating, tin spraying, etc. Different surface treatments have different characteristics and applicable scenarios, which need to be selected according to specific needs.
- Safety regulations: thick copper circuit board suppliers need to follow the relevant safety regulations to ensure that the circuit boards provided will not cause harm to personal safety and the environment. For example, low-smoke halogen-free materials need to be used to manufacture circuit boards to reduce the risk of fire; the need to use environmentally friendly materials to carry out surface treatment to reduce environmental pollution.
In short, thick copper circuit board suppliers need to follow a series of design specifications and safety norms to ensure that the circuit boards provided comply with industry standards and customer requirements, while guaranteeing safe and reliable use.
