Purple Corrosion Resistant High Tg PCB Medical Imaging Equipment

♦ What's High-Tg?

Tg refers to the glass transition temperature. When the substrate is exposed to high temperatures, it will change from a glass state to a rubber state. High Tg PCB refers to a circuit board that can withstand higher temperatures without deforming or turning into rubber. Materials with a glass transition temperature above 170°C are usually classified as high Tg PCBs, those above 150°C are mid-range Tg PCBs, and those above 130°C are low Tg PCBs.

♦ Features of High-Tg PCB?

• • ​​High heat resistance​​: It can maintain stable physical and electrical properties in high temperature environments (such as higher soldering temperatures in lead-free processes), and reduce the floating phenomenon of PCB pads during infrared heat melting, welding and thermal shock.
  • ​​Low coefficient of thermal expansion (CTE): It can reduce warping and deformation caused by temperature, prevent the degradation of plated through-hole performance and copper breakage in multi-layer PCBs, and improve product reliability.
  • ​​Excellent mechanical strength​​: Good mechanical strength at high temperatures, more reliable during transportation, installation and use, and reduce damage caused by mechanical stress.

♦ Application fields of High-Tg PCB

• • Communication field: widely used in wireless base stations, optical fiber communications, satellite communications and other equipment, supporting high-speed signal transmission, adapting to high temperature and high frequency environments, and ensuring stable operation of communication networks.
  • Automotive field: used in vehicle computers, engine control units, new energy battery management systems, etc., to withstand high temperatures, vibrations and complex environments, and improve the reliability of automotive electronic systems.
  • Industrial field: suitable for industrial automation equipment, PLCs, converters, etc., can work stably in high temperature, high humidity, and strong vibration environments, ensuring long-term and reliable operation of industrial equipment.
