High-TG PCB
Boards built with high glass-transition-temperature laminate, which stays mechanically stable at higher operating temperatures.

Overview
Boards built with high glass-transition-temperature laminate, which stays mechanically stable at higher operating temperatures.
Why it matters
Standard FR-4 begins to soften at temperatures reachable during lead-free reflow or sustained high-power operation. High-Tg materials hold their mechanical properties further into that range.
Typical Applications
- Power electronics
- Automotive under-hood electronics
- Assemblies with multiple reflow cycles
- Industrial equipment in hot environments
Manufacturing Considerations
- Higher Tg generally trades off against material cost and can affect drill and etch behavior
- Thermal expansion characteristics still need matching to plated-via reliability requirements
- Not automatically necessary for every high-temperature application — worth evaluating against the actual thermal profile
