批发供应有铅锡丝

锡丝主要由两部分构成：合金和焊剂。合金成份分为锡铅、无铅 一般由客户指定；焊剂（通常所说的“松香”）的选择根据客户不同的使用工艺、不同的被焊材质选择不同种类焊剂的锡丝，本公司经过多年的实践经验研制出多种不同配方焊剂的锡丝供客户有针对性选择，每种配方具有不同的效果，客户在选用时请认清产品编号，以免造成不必要的质量问题。合金成份分为锡铅合金、无铅合金、其成份比例与锡条相对应，根据客户需求选择相应合金型号。                                    类型                                    牌号                                    合金成份（wt%)                                    牌号                                    合金成份（wt%)                                                    锡铅合金                                    63/37                                    Sn63/ Pb37                                    45/55                                    Sn45/ Pb55                                                    60/40                                    Sn60/ Pb40                                    40/60                                    Sn40/ Pb60                                                    55/45                                    Sn55/ Pb45                                    35/65                                    Sn35/ Pb65                                                    50/50                                    Sn50/ Pb50                                    30/70                                    Sn30/ Pb70                        ★ 其它规格可依客户需求提供                                    焊剂（松香）类型                                    用途                                                    V 系列松香型                                    适用于电子类及相关组件的电子补焊，焊接后残留物阻抗高，不漏电，能通过高压测试，是电子行业最常用的锡丝。                                                    M 系列免洗型                                    适用于要求残留物少、绝级阻抗高、板面干净等PCB板补焊。                                                    N 系列镀镍型                                    适用于镍材、表层镀镍的元器件、线材、端子、插座 灯头等硬质材料的焊接。                                                    S 系列火枪烧焊型                                    适用于高中档手表、手环表、套链、胸花、鞋花、发夹等锌合金饰品的烧焊缝填加工。                                                    T 系列特种锡丝                                    适用于不锈钢、锌合金、铝灯头等的焊接，此类焊剂为非松香型，焊接后残留物可用水清洗。                                                    实芯锡丝                                    本品为实芯，不含焊剂，适用于保险丝、金属管件等特殊用途。                        锡丝的线径从φ0.3mm～φ5.0mm可以依据客户需求定做，通常备有：φ0.3mm、φ0.5mm、φ0.8mm、φ1.0mm、 φ1.2mm等规格。⑴良好的焊锡性能；⑵焊接时飞溅松香极少；⑶线内焊剂分布均匀，润湿性好；⑷无异味、无刺激性气味、无毒害身体之气味，烟雾少，带有淡淡环保香味；⑸卷线整齐、美观、表面光亮。
