1、無機：無機系列助焊劑的化學作用強，助焊性能非常好，但腐蝕作用大，屬于酸性焊劑。由于它溶解于水，所以又稱為水溶性助焊劑，它包括無機酸和無機鹽兩種。含有無機酸的助焊劑的主要成分是鹽酸、氫氟酸等，含有無機鹽的助焊劑的主要成分是氯化鋅、氯化銨等，它們使用后必須立即進行非常嚴格的清洗，因為任何殘留在被焊件上的鹵化物都會引起嚴重的腐蝕。無機系列助焊劑通常只用于非電子產(chǎn)品的焊接，在電子設(shè)備的裝聯(lián)中嚴禁使用這類無機系列的助焊劑。衢州助焊劑銷售杭州正盟環(huán)保，生產(chǎn)質(zhì)量環(huán)保，環(huán)保級助焊劑。</p><div

style="text-indent:25px">【正盟環(huán)保】免清洗助焊劑要使焊接后的PCB板面不用清洗就能達到規(guī)定的質(zhì)量水平，助焊劑的選擇是一個關(guān)鍵，通常對免清洗助焊劑有下列要求： ①低固態(tài)含量：2%以下傳統(tǒng)的助焊劑有較高的固態(tài)含量（20～40%）、中等的固態(tài)含量（10～15%）和較低的固態(tài)含量（5～10%），用這些助焊劑焊接后的PCB板面留有或多或少的殘留物，而免清洗助焊劑的固態(tài)含量要求低于2%，而且不能含有松香，因此焊后板面基本無殘留物。 ②無腐蝕性：不含鹵素、表面絕緣電阻>1.0×1011Ω 傳統(tǒng)的助焊劑因為有較高的固態(tài)含量，焊接后可將部分有害物質(zhì)“包裹起來”，隔絕與空氣的接觸，形成絕緣保護層。而免清洗助焊劑，由于極低的固態(tài)含量不能形成絕緣保護層，若有少量的有害成分殘留在板面上，就會導致腐蝕和漏電等嚴重不良后果。因此，免清洗助焊劑中不允許含有鹵素成分。</p><p style="text-indent:25px">【正盟環(huán)保】【助焊劑小知識】助焊劑各成分的作用被焊金屬工件表面存在氧化物、灰塵等污垢，阻礙工件基體金屬和焊料之間以原子狀態(tài)相互擴散，因此必須去除氧化物等以使表面清潔露出金屬基體，但是被清潔的金屬基體表面的原子在大氣中又立刻被氧化，在焊接溫度下，氧化速度更快。所以在焊接過程中加入助焊劑，用來協(xié)助提供沒有氧化層的金屬表面，并保持這些表面的無氧化物狀態(tài)，直到焊錫與金屬表面完成焊接過程。同時依靠焊劑的化學作用，與被焊金屬表面的氧化物化合，在焊接溫度下形成液態(tài)化合物，使被焊金屬部位表面的金屬原子與熔融焊料的原子相互擴散，以達到錫焊連接的目的。在焊接過程中助焊劑還能促進焊錫的流動和擴散，通過減小表面不平度來影響焊錫表面張力在焊錫擴散方向上的平衡。理想的助焊劑除化學活性外，還要具有良好的熱穩(wěn)定性、粘附力、擴展力、電解活性、環(huán)境穩(wěn)定性、化學官能團及其反應(yīng)特性、流變特性、對通用清洗溶液和設(shè)備的適應(yīng)性等。助焊劑的上述作用都是通過其中的活化劑、溶劑、表面活性劑等成分的作用來實現(xiàn)的。浙江廠家直銷助焊劑，質(zhì)量環(huán)保助焊劑。</p><div

style="text-indent:25px">【正盟環(huán)保】助焊劑作用助焊劑中的主要起作用成分是松香，松香在260攝氏度左右會被錫分解，因此錫槽溫度不要太高．助焊劑是一種促進焊接的化學物質(zhì)。在焊錫中，它是一種不可缺少的輔助材料，其作用極為重要。溶解焊母氧化膜在大氣中，被焊母材表面總是被氧化膜覆蓋著，其厚度大約為2×10-9～2×10-8m。在焊接時，氧化膜必然會阻止焊料對母材的潤濕，焊接就不能正常進行，因此必須在母材表面涂敷助焊劑，使母材表面的氧化物還原，從而達到消除氧化膜的目的。被焊母材再氧化母材在焊接過程中需要加熱，高溫時金屬表面會加速氧化，因此液態(tài)助焊劑覆蓋在母材和焊料的表面可防止它們氧化。臺州求購助焊劑</p><p
