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...
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...
