千位锡丝的FLUX的耐热性良好 
ECO SOLDER HVP改良了耐热性，为不易焊接的大热容器零件、SLIDE焊接等、长时间被曝晒在高温的焊接作业环境开发之松香芯锡丝。 适用温度范围很广，约300℃~430℃范围中可良好地焊接。 而且，ESC21和RMA02同样抑制了FLUX和锡球的飞溅、FLUX残渣接近透明无色，焊接后外观良好。

千住锡丝特点：
1.润湿性好、上锡速度快、焊锡时不会溅弹松香、线内松香分布均匀、不断芯、烟雾小、无恶臭气味、不含危害身体健康之挥发性气体、烙铁头浮渣少，自动焊锡机焊接走线时锡丝不会缠结、不阻塞导管、松香透明、不变色、绝缘电阻高、低残留、免清洗
2.杂质含量极少，锡线外观光亮整齐；
3.免清洗、残留少：采用纯白透明加氢松香制作，焊点光亮、离子残留少、洁净美观、绝缘电阻高、磨蚀性极低；
4.通用性好、焊锡快：采用国际标准助焊剂和真空密封生产工艺，润湿时间短，铺展面积大，大程度发挥焊锡活性，使焊铜材和焊镍材同时使用，大大提高了效率
5.气味清新、烟雾少：采用环保无味助焊剂，不含REACH控制的化学物质、焊接时不飞溅、烟雾少、气味清新；
5.机器自动焊锡流畅不用返修：采用和特的助焊剂制作工艺，只要稍微调整松香芯比例，便可用于机器自动焊锡，不连锡，无需返修
6.焊点时有效减少了界面化合物（IMC）层的厚度，使焊点坚固持久，抗机械能力强，并且在焊点表面形成一薄层透明保护膜，避免了焊点与空气直接接触，保持焊点性能稳定
7.微小间距一次拖焊到位
