锡粉的编号及直径尺寸大致如下,下表依据【IPC J-STD-006A】,但各家锡膏供货商其实会有其他锡粉的编号规格,比如说为了因应需求而有Type4.5或Type7、Type8,规范之外的规格可能各家就会有些许的不同 锡粉的直径越小,基本上落锡量就越好。 因为颗粒小就越容易滚落下钢板的开口,也就是说越容易透过钢板印刷于电路板...
锡膏(solder paste)的基本知识介绍 锡粉(Powder) 锡粉也就是金属合金,主要用途在体现焊接的强度,其主要成份包含有下列几种:Sn(锡 )、Ag(银)、Cu(铜)、Bi(铋)。 锡粉会因为不同锡膏的编号而有不同成分及比率组成,但既使是相同的编号但厂牌不一样,其成份也会有些许的不一样,有些可能是为了避开专利,有些则...
錫膏(Solder paste)是現代化科技進步不可或缺的重要材料之一,它被用來焊接電子零件於電路板(PCB)上,讓我們有機會享受日新月異的科技產品。 也因為有錫膏的發明才間接促成了電子組裝科技的極小化,讓原本大如磚頭的大哥大黑金剛手機可以變身為口袋裝得下且功能超多的智慧型手機。 而錫膏之所以被稱之為「膏」,則是...
of a new type of lead-free solder paste Sn-07Ag-05Cu +BiNi(SACBN07) was investigated by conducting a series of comparison experiments with SAC305 and SAC0307 solder paste.The results show that wettability of SACBN07 is almost equal to SAC305,and better than that of SAC0307 solder paste....
