焊劑芯焊錫絲在zai焊han接jie時shi
，焊han點dian是shi潤run滑hua光guang亮liang的de
，沒mei有you任ren何he虛xu焊han假jia焊han現xian象xiang。將jiang此ci類lei焊han錫xi絲si存cun放fang在zai一yi定ding溫wen度du的de錫xi爐lu內nei
，焊han錫xi絲si會hui熔rong化hua
，熔rong液ye也ye是shi有you光guang澤ze無wu雜za質zhi。在zai焊han接jie過guo程cheng中zhong要yao注zhu意yi焊han錫xi技ji巧qiao，一yi手shou拿na著zhe焊han錫xi絲si，一yi手shou拿na著zhe電dian烙lao鐵tie，先xian在zai電dian烙lao鐵tie上shang鍍du上shang一yi層ceng錫xi
，這zhe時shi為wei了le方fang便bian焊han接jie
，然ran後hou將jiang烙lao鐵tie頭tou往wang引yin腳jiao上shang鍍du錫xi，即ji是shi將jiang烙lao鐵tie頭tou上shang的de焊han錫xi絲si熔rong液ye塗tu抹mo在zai引yin腳jiao上shang
，這zhe也ye給gei引yin腳jiao進jin行xing了le預yu熱re
，極ji大da的de方fang便bian了le焊han錫xi絲si的de焊han接jie。

        焊han劑ji芯xin焊han錫xi絲si還hai有you一yi個ge蘸zhan錫xi法fa，過guo程cheng就jiu是shi先xian用yong烙lao鐵tie頭tou蘸zhan取qu少shao量liang鬆song香xiang和he酒jiu精jing後hou取qu錫xi，再zai把ba烙lao鐵tie頭tou斜xie刃ren麵mian往wang引yin腳jiao上shang靠kao，讓rang焊han錫xi流liu在zai引yin腳jiao上shang慢man慢man冷leng卻que。其qi實shi這zhe種zhong方fang法fa是shi不bu好hao控kong製zhi住zhu錫xi量liang的de，撤che離li烙lao鐵tie頭tou時shi也ye比bi較jiao容rong易yi拉la出chu毛mao刺ci。可ke以yi將jiang可ke調tiao節jie溫wen度du的de電dian烙lao鐵tie調tiao節jie到dao指zhi定ding溫wen度du，焊han劑ji芯xin焊han錫xi絲si能neng夠gou熔rong化hua
，還hai不bu會hui產chan生sheng大da量liang的de煙yan霧wu。這zhe也ye不bu失shi為wei一yi個ge好hao的de焊han錫xi方fang法fa。
