Splet06. jun. 2024 · 안녕하세요. PCB해결사 휴민스입니다. FR4를 흔히 사용하는 PCB에서 유리전이온도를 나타내는 Tg가 무엇을 의미하는지 알아보도록 하겠습니다. 유리전이온도 Tg의 값을 아는 경우는 많습니다.첨부와 같이 데이타 시트가 존재하니깐 그렇겠지요... 우선 FR4는 흔히 일반과 High-Tg 제품으로 구분됩니다. Splet2、tg:玻璃态转化温度, 是玻璃态物质在玻璃态和高弹态(通常说的软化)之间相互转化的温度。tg值越高,通常其耐热能力及尺寸稳定性越好。 3、cti:相对漏电指数,单位为v。 4、cte:热胀系数,cte值越低,尺寸稳定性越好,反之越差。
