In scenarios such as industrial power distribution and high-temperature sensing, ordinary printed circuit boards (PCBs) are prone to warping, delamination, and reduced insulation when exposed to high temperatures and repeated temperature changes for a long time, affecting the stable operation of equipment. The high glass transition temperature (high Tg) printed circuit boards specially designed for such scenarios effectively solve the above pain points with high-quality substrates and precision craftsmanship, providing stable support for various power distribution and sensing equipment.
Core Advantages of the Product
Combined with the actual needs of power distribution and high-temperature sensing scenarios, the product has formed multiple core advantages, fully adapting to the harsh service requirements of industrial equipment.
- Strong High-Temperature Stability: Adopting high-Tg special substrates, the heat resistance is far superior to conventional boards. It will not soften or warp under long-term high temperatures and cyclic temperature changes, avoiding poor contact and insulation failure.
- Stable Insulation Performance: It has excellent voltage resistance and leakage resistance. Even in harsh environments such as high temperature, humidity, and dust, it can maintain stable insulation and signal transmission, meeting the needs of high-voltage isolation in power distribution and precise signal collection of sensors.
- Weather Resistance and Anti-Aging: It can resist the erosion of oil stains, moisture, and aging, with a longer service life than ordinary PCBs, greatly reducing the cost of equipment replacement and maintenance.
- Suitable for Dense Wiring: It has excellent thermal conductivity and structural strength, supporting high-density wiring, multi-layer interconnection, and high-power component mounting, improving equipment integration and space utilization.
- Precise Manufacturing Process: It meets industrial-grade standards, with controllable aperture, impedance, flatness, and interlayer alignment accuracy, adapting to the special assembly needs of sensors and power distribution terminals.
These advantages work together to not only solve the pain points of high-temperature failure of ordinary PCBs but also provide solid guarantee for the long-term stable operation of equipment.
Main Features of the Product
Based on core advantages, the product has practical and targeted features, which are different from ordinary PCBs and more suitable for the exclusive needs of power distribution and high-temperature sensing.
- Supported by high-Tg substrates, it can operate stably under long-term high-temperature electrification, resisting the impact of welding high temperature and equipment self-heating, and is not easy to delaminate or crack.
