WebDec 11, 2024 · FR4 lead-free KB-6168LE Tg value is 185℃, (5% weight loss) Td value is 359℃. Studies have shown that the Td value of conventional FR4 plates is above 300℃, while the Td value of leaded soldering fully meets the temperature of 240~270℃, so why is there a lead-free version? WebMar 24, 2024 · Standard FR4 has a Tg value of ~130 °C, but a substrate with a high-Tg resin can bring the Tg value up to ~170 °C. If your substrate and conductor CTE values were closely matched at low temperature, and your board will operate at high temperatures, then you should opt for a substrate with a higher Tg value.
