Print circuit boards (PCBs) are of great importance to power and control systems, and handle high voltage applications In the case, special considerations are required in the design. High voltage PCBs are commonly used in industries such as telecommunications, industrial automation, medical devices, and robotics. This article examines key factors in PCB design and high voltage best practices to ensure security, reliability and performance. It can rise above 100 V and up to a maximum of several kilovolts depending on the application. These PCBs require an accurate selection of materials, distances and insulation techniques to prevent ARC, electrolysis and reliability issues. For sophisticated and reliable high voltage PCB solutions, Global Well offers the latest manufacturing services tailored to a wide range of industrial applications. Material Selection
The selection of PCB material plays an important role in determining the dielectric strength and insulation properties of the board. Common materials used in high voltage PCB designs include:
FR4: Standard material with a dielectric thickness of 20 kV/mm suitable for medium high voltage applications.
Polyimide: Provides better thermal resistance and mechanical strength. Characteristics.
2. Correct distance and correct release
Adequate distance between senior elements is important to prevent arcing and ensure safe operation. Designers determine the minimum emission of a particular voltage level according to industry standards such as IPC-2221. General guidelines include
clearance of at least 0.6 mm. and coating.
3. Layer Stacks and Insulation
With multi-layer PCB stacks, voltage insulation can improve and minimize electromagnetic interference (EMI). A typical high voltage PCB can include:
- Signal layer for low voltage control.
- Current layer with a suitably insulated high voltage lens. Gives security.
4. Trace Design and Width Optimization
Thicker traces are required to carry high power efficiently. Calculating the required track width ensures proper power handling and reduces resistance warming. Designers use tools such as IPC-2221 and online PCB trace calculators to use
- Copper thickness
- Create the best track dimensions.
5. Separation Technology and Coating
Applying protective coatings and insulation technology improves the durability and safety of PCBs. Frequently used methods include:
Compatible coating: Protective layer to prevent moisture and contamination. : A physical barrier to prevent surface tracking between high voltage traces.
