Among High-Tg PCB manufacturers, Xekera Systems is a name of repute. There is a great demand for boards with high Tg value due to advancements in electronic technology for applications involving high temperatures. Tg, or glass transition temperature, is one of the most important properties of epoxy materials.
Glass transition temperature (Tg) denotes the temperature region where the base material—either glass or polymer—changes from its glassy, solid, and rigid form to a soft and plastic form. Beyond Tg, the PCB substrate not only becomes soft, it deforms and melts, with a sharp decline in its electrical and mechanical properties.
Xekera Systems recommends using materials with Tg value at least 25-30 degrees higher than the temperature during fabrication and operation of the board. For instance, a PCB with a rated Tg value of 150 °C should only be used for applications that remain below 125 °C.
Regular PCBs with standard thermal performance
Improved thermal performance for moderate applications
Superior thermal performance for demanding applications
Capability to withstand high temperatures without damage, maintaining structural integrity even under extreme thermal stress.
Superior plated through-hole reliability with better mechanical properties that prevent barrel cracking and connection failures.
Minimal thermal expansion reduces mechanical stress on components and solder joints during temperature cycling.
Extended operational life with improved resistance to delamination under thermal and mechanical stress.
Materials with high Tg values exhibit better mechanical properties and higher chemical resistance compared to standard FR-4 material. Additionally, higher the Tg value, better is the temperature withstanding capability of the material.
Modern electronic equipment complies with RoHS and WEEE directives and does not use hazardous substances. During assembly, lead-free processes use higher temperatures than regular leaded processes. Therefore, materials with higher Tg values are more in demand to withstand these elevated processing temperatures.
