銅鏡腐蝕性：助焊劑的腐蝕性大小是對酸性強弱對基材影響的進一步驗證，衡量腐蝕性大小一般是在使用相當普遍的基材銅上做銅鏡腐蝕試驗，金華助焊劑廠家。這項指標也是需要在腐蝕性和可焊性之間做權(quán)衡。表面絕緣電阻：表面絕緣電阻的反應的是助焊劑焊后產(chǎn)品可靠性，按照不同的測試標準對表面絕緣電阻值的要求也不一樣，按照GBT9491-2002標準SIR大于1011Ω，而按照IPC J-STD-004標準，SIR大于108Ω，因測試方法不同，兩者的對比并無意義，金華助焊劑廠家。但可以確定的是SIR值是越大對焊后產(chǎn)品越有利。電化學遷移：電化學遷移也是對表面絕緣電阻值的進一步要求，金華助焊劑廠家，在更極端的環(huán)境下考察助焊劑的表面絕緣電阻。當然該項指標亦越大對焊后產(chǎn)品越有利。除上述詳細的技術(shù)參數(shù)的考慮，其次還需結(jié)合所需要裝配的電子產(chǎn)品的類別或技術(shù)要求，選擇合適的助焊劑產(chǎn)品；需要對所選助焊劑，進行試驗驗證和有效評估。***環(huán)保級助焊劑生產(chǎn)加工，現(xiàn)貨批發(fā)。金華助焊劑廠家</p><div

鹵素含量：鹵素具有較強的奪取電子能力，微量的鹵素存在會使得助焊劑的可焊性大幅提升，但鹵素的存在不僅有環(huán)保壓力也會給產(chǎn)品的可靠性造成一定影響。故助焊劑鹵素含量因應用場景而定。比重：助焊劑中溶劑載體與其他組分的密度相差較大，助焊劑在儲存和使用過程中因為揮發(fā)作用而損失掉，造成比重的變化，故比重一定程度上可以反映助焊劑濃度的變化，故比重應用于生產(chǎn)中的管控指標。固含量：固含量與焊后殘留量（即干凈度）有直接關(guān)系，但非對應關(guān)系，主要是因為測試溫度和實際使用溫度上存在差異。所以固含量的是在可焊性和焊后干凈度之間做權(quán)衡。金華助焊劑廠家正盟環(huán)保，現(xiàn)貨供應，***助焊劑。</p><div

H2O和（BTA2Cu）2CuCl2?H2O，且聚合物和金屬銅的表面平行，非常穩(wěn)定。BTA在Cu 2 O層上成膜比在 CuO層上成膜更容易，而且膜的厚度厚了近一倍。 BTA的濃度大于l0-3 mol／L時，就可以很好地抑制銅的腐蝕。助焊劑廠家直供，一手貨源！金華助焊劑廠家</p><p

2、有機：有機系列助焊劑的助焊作用介于無機系列助焊劑和樹脂系列助焊劑之間，它也屬于酸性、水溶性焊劑。含有有機酸的水溶性焊劑以乳酸、檸檬酸為基礎(chǔ)，由于它的焊接殘留物可以在被焊物上保留一段時間而無嚴重腐蝕。所以，可以用在電子設(shè)備的裝聯(lián)中，但是通常不用在SMT的焊膏中，因為它沒有松香焊劑的粘稠性。 3、樹脂：在電子產(chǎn)品的焊接中使用比例較大的是樹脂型助焊劑。由于它只能溶解于有機溶劑，故又稱為有機溶劑助焊劑，其主要成分是松香。松香助焊劑有液態(tài)、糊狀和固態(tài)三種形態(tài)，固態(tài)的助焊劑適用于烙鐵焊，液態(tài)和糊狀的助焊劑分別適用于波峰焊。松香為單體時，化學活性較弱，對促進焊料的潤濕往往不夠充分，所以需要添加少量的活性劑，以便提高它的活性。金華助焊劑廠家</p><p
