虽然无银，却能保证良好浸润性千住锡丝ECO SOLDER CORED NEO M24AP
特点
1.采用即効性活性剂，初期浸润迅速
2.改良助焊剂流动性，使浸润性扩散顺利
3.采用耐热性强的活性剂，实现了良好的切断性，抑制了拉尖及桥连的产生
4.削减了助焊剂产生的气体，减少飞溅
5.由本公司自行生产，能提供产品
6.Sn-Cu-Ni-Ge等与其他Sn-Cu系焊锡混合亦可
可在短时间内进行焊接

千住焊锡丝SPARKLE ESC21 ～ 润湿性(扩散性)良好M705 F3
无铅焊材与一般钖铅焊材比较之下，焊材的润湿性(扩散性)较差是主要的缺点，比较一般钖铅无铅的扩散率约只达到一般钖铅的90%以下。SPARKLE ESC(ECO SOLDER CORED)，是针对无铅化而开发之松香芯钖丝，比较一般的无铅焊材，大幅提高润湿性(扩散性)及切断性，进而实现了可与一般钖铅相同之作业性。SPARKLE ESC21改良了过去产品ESC的作业性，以及润湿性焊材中FLUX的飞溅问题。烙铁头设定在低温时焊接性依然良好，并可延长烙铁头使用寿命。焊接后残渣接近无色透明、外观良好。
