Application of High Voltage Resistance Slurry | Key Conductive Materials for High Voltage Circuit Boards

Introduction

In modern electronics industry, high-voltage circuits are widely used in key fields such as medical equipment, new energy vehicles, power transmission, communication base stations, and industrial control. The stable and reliable operation of these circuits relies on their core foundation - the high-voltage circuit board. The key material that endows the substrate with conductivity, resistance, and insulation functions is the special functional material: advanced institute technology's high-voltage resistor paste. It is a paste like material made by precise ratio of conductive phase, glass phase, and organic carrier, which becomes an indispensable electronic functional layer on the substrate through printing and sintering processes.

On high-voltage circuit substrates, resistor paste is mainly used to make components such as high-voltage dividers, sampling resistors, discharge resistors, and voltage equalization rings. These components directly determine the voltage division accuracy of the circuit, the accuracy of signal detection, and the overvoltage protection capability of the system. The thick film resistor network formed by the slurry can effectively manage and balance high potential differences, ensure safe energy transmission along the designed path, and avoid dielectric breakdown caused by energy concentration. It is the "voltage regulator" and "safety valve" of the entire circuit.

3、 The uniqueness of performance requirements

Compared with ordinary resistor paste, high-voltage applications place extreme demands on its performance. The top priority is excellent high-voltage stability, which means that the resistance value changes very little under long-term high-voltage loads. Secondly, it has extremely high voltage resistance, which can withstand electric fields of tens of thousands of volts or even higher without being broken down. In addition, it is necessary to have a low temperature coefficient of resistance (TCR) to ensure stable performance over a wide temperature range, as well as excellent resistance to pulse impact to cope with instantaneous voltage surges.

By precise control of the morphology, particle size distribution, and content of conductive phase particles, the desired resistivity and electrical performance can be achieved. The selection and design of glass phases are crucial, as they require perfect wetting and encapsulation of conductive phases during sintering to form a dense and defect free structure, providing strong mechanical support and extremely high dielectric protection. Advanced printing and sintering processes ensure a strong bond between the slurry and the substrate, with clear line edges and no microscopic defects that may cause electric field concentration.
