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，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。深圳錫膏助焊劑買助焊劑找正盟環(huán)保。</p><div

可焊性與腐蝕性是相互矛盾的一對指標，為了使助焊劑具有一定的消除氧化物的能力，并且在預熱和焊接的整個過程中均能保持一定程度的活性，就必須包含某種酸。在免清洗助焊劑中用得多的是非水溶性醋酸系列，配方中可能還有胺、氨和合成樹脂，不同的配方會影響其活性和可靠性。不同的企業(yè)有不同的要求和內(nèi)部控制指標，但必須符合焊接質(zhì)量高和無腐蝕性的使用要求。助焊劑的活性通常是用pH值來衡量的，免清洗助焊劑的pH值應控制在產(chǎn)品規(guī)定的技術條件范圍內(nèi)（各生產(chǎn)廠家的pH值略有不同）。

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）有直接關系，但非對應關系，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衡。廠家供應環(huán)保級助焊劑，***，助您安全焊接。</p><div
