Diagnostic and imaging equipment have extremely high requirements for the high temperature resistance, high stability, and high precision of supporting PCBs. High glass transition temperature (high Tg) printed circuit boards, with a core Tg value ≥ 170℃, meet various harsh requirements of the equipment and are the core supporting components of medical diagnostic equipment.

Core Performance Advantages of High Tg Printed Circuit Boards
Targeting the core needs of diagnostic and imaging equipment for long-term high-temperature operation, accurate signal transmission, and precise structure, this product relies on high Tg characteristics to create four core performance advantages, as follows:
- High Temperature Resistance: Tg value ranges from 170℃ to 180℃, which can withstand the high temperature of 260℃ lead-free soldering, avoid substrate softening and delamination, adapt to long-term high-temperature operation of equipment, and reduce the probability of failure.
- High Stability: Low coefficient of thermal expansion reduces warpage and dimensional deviation caused by temperature, adapts to multi-layer board design, ensures the performance of plated through holes, and meets the precise installation needs of equipment.
- Excellent Electrical Performance: Low dielectric constant (Dk≈3.5±0.05@1GHz) and low dielectric loss (Df≤0.002) reduce signal attenuation and crosstalk, ensuring the accuracy of diagnosis and treatment data.
- High Reliability: Resistant to chemical corrosion, compliant with RoHS environmental standards, halogen-free and non-toxic, suitable for the strict safety and environmental requirements of the medical field.
The core advantages of the product accurately match the core needs of diagnostic and imaging equipment, providing a solid guarantee for the long-term stable and accurate operation of the equipment.
