Behind the brilliant achievements of the electronics industry, PCB (printed circuit board) is the heart of electronic products, and its production process has extremely strict requirements for environmental cleanliness. The construction of the 10,000-level PCB purification workshop and the design of power supply and distribution are the heroes behind all this. In this article, China Exportsemi Net will try to explore this key link in depth and reveal its design secrets.
1. Safety: the cornerstone of design
Safety is the cornerstone of power supply and distribution design. According to the national electrical safety standards, all electrical systems must be equipped with grounding devices, leakage protection devices and overvoltage protection devices. For example, an electrical safety upgrade project for a PCB production floor reduced the accident rate by 75% by adding leakage protection devices.
2. Reliability: the guarantee of production
The reliability of power supply and distribution design is directly related to the continuity of production. Taking a large PCB manufacturer as an example, by introducing a dual-loop power supply system, even in the case of a power supply failure, production can be ensured without interruption, and the average annual production efficiency of 99.9% is guaranteed.

3. Economy: cost optimization
On the premise of satisfying safety and reliability, the economy of power supply and distribution design is equally important. A cost analysis showed that by optimizing cable routing and equipment configuration, a PCB cleanroom reduced energy consumption by 20 percent, significantly reducing operating costs.
4. the special requirements of the clean room environment
Class 10,000 PCB cleanroom has extremely high requirements for cleanliness, usually requiring ISO 4 or higher. For example, a clean plant was able to control the concentration of particulate matter in the air to no more than 3,520 per cubic meter through the use of high-efficiency filters and well-sealed electrical equipment.
5. the integration of intelligent technology
The application of intelligent technology has brought revolutionary changes to the power supply and distribution system. According to an industry report, the PCB clean workshop with an intelligent monitoring system can detect and solve more than 90% of potential electrical problems in advance, significantly improving the stability and reliability of the system.
In short, the power supply and distribution design of the 10,000-level PCB purification workshop is a comprehensive project involving safety, reliability, economy, cleanliness and intelligence. Through continuous optimization of design, this behind-the-scenes hero not only ensures the efficient operation of PCB production, but also promotes the healthy development of the entire electronics industry. With the continuous progress of technology, the future power supply and distribution system will be more efficient, stable and safe, providing solid support for the continuous prosperity of the electronics industry.
