DSC为业界评判覆铜板材料Tg的通用方法,但随着无铅覆铜板产品中填料比例增加和交联固化度提高,DSC法Tg曲线存在拐点不明显导致结果不准确问题。通过对比DMA与DSC测试原理和DMA法测量系统分析,结果表明对于含填料、PN固化的无铅兼容覆铜板采用DMA测试Tg的稳定性与重现性更好,更能准确地表征板材Tg。
DSC為業界評判覆銅闆材料Tg的通用方法,但隨著無鉛覆銅闆產品中填料比例增加和交聯固化度提高,DSC法Tg麯線存在枴點不明顯導緻結果不準確問題。通過對比DMA與DSC測試原理和DMA法測量繫統分析,結果錶明對于含填料、PN固化的無鉛兼容覆銅闆採用DMA測試Tg的穩定性與重現性更好,更能準確地錶徵闆材Tg。

DSC is the universal method of CCL to evaluate the curing degree, but with increase of the content of ifller and improved curing degree, the inlfection point of Tg curve of DSC is not obvious result in Tg inaccurate. Through the comparison of DMA and DSC testing principle and DMA measurement system analysis, the results show that for the ifller containing PN curing of lead-free compatible CCL with better stability and more accurate characterization of Tg with DMA.
