style="text-indent:25px">【正盟環(huán)保】樹脂系列助焊劑在電子產(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。松香在固態(tài)時呈非活性，只有液態(tài)時才呈活性，其熔點為127℃活性可以持續(xù)到315℃。錫焊的溫度為240～250℃，所以正處于松香的活性溫度范圍內(nèi)，且它的焊接殘留物不存在腐蝕問題，這些特性使松香為非腐蝕性焊劑而被廣泛應用于電子設備的焊接中。為了不同的應用需要，松香助焊劑有液態(tài)、糊狀和固態(tài)3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。</p><p
