        1、組件功率測試數據與焊帶電阻率測試數據有較好的匹配性。

        2、測試結果表明,除力博、三能外,其他各家焊帶對組件的電性能實現能力均不低于產線量產焊帶。

        3、三能的焊帶所制組件中有一塊功率與其他數據差距較大,此塊組件可視為異常。

        十、總結

        1、各家焊帶尺寸測試及電阻率、延伸率、抗拉強度、焊接拉力測試均合格,其中環陽、晶合、力博三家焊帶焊接拉力最小值接近臨界點,可能出現虛焊現象。

        2、晶合、力博有嚴重過焊情況,判為不合格;寶裕、三能、環陽也有不同程度的過焊現象。

        3、晶聯、力博、環陽三家焊帶鹽霧試驗不合格。

        4、組件功率測試數據與焊帶電阻率測試數據有較好的匹配性;除力博、三能外,其他各家焊帶對組件的電性能實現能力均不低于產線量產焊帶。

        5、綜合各項測試結果,斯卓、易通、兆伏焊帶樣品性能較優,其次為寶裕;晶聯作為超軟態焊帶,不適合目前產線條件,可在后續技改時考慮繼續驗證。
