High TG (Glass Transition Temperature) FR-4 PCB is engineered for applications requiring extended thermal performance beyond standard FR-4 capabilities. With a TG of 150°C to 170°C, this board maintains dimensional stability and mechanical integrity under elevated temperatures, making it ideal for automotive under-hood systems, industrial power electronics, and LED lighting. The enhanced thermal reliability reduces the risk of delamination, pad lifting, and via cracking during assembly and operation. Compatible with lead-free soldering processes (up to 260°C peak reflow), this board meets the demands of modern high-temperature electronics assembly.
