2、有機(jī)：有機(jī)系列助焊劑的助焊作用介于無機(jī)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(jī)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(shí)間而無嚴(yán)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?yàn)樗鼪]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(jī)溶劑，故又稱為有機(jī)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(shí)，化學(xué)活性較弱，對(duì)促進(jìn)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。金華助焊劑品牌</p><p
