一种在电芯盖帽进行铝丝焊接键合的方法
摘要：
本发明揭示了一种在电芯盖帽进行铝丝焊接键合的方法，包括以下步骤：步骤（a）对电芯盖帽进行电镀处理；（b）在镀液中掺杂磷元素；（c）在掺杂磷元素的镀液中对电芯盖帽进行化学镀镍；（d）铝丝焊接。本发明提供的一种在电芯盖帽进行铝丝焊接键合的方法，通过先电镀得到平坦的工件表面再进行化学镀镍磷，可极大的改善了铝丝焊接键合强度，同时由于镍磷镀层对不锈钢和铝都有着友好的粘贴特性，避免了工件金属层和铝丝直接接触而造成电阻增加、电路损耗增加、键合强度下降的问题，同时提高效率、品质，降低成本。
摘要（英）：

The invention discloses a method for aluminum wire welding bonding on an electric core cap. The method comprises the following steps that (a) electroplating treatment is conducted on the electric corecap; (b) a phosphorus element is doped in a plating solution; (c) chemical nickel-plating is conducted on the electric core cap in the plating solution doped with the phosphorus element; and (d) aluminum wire welding is conducted. According to the method for aluminum wire welding bonding on the electric core cap, a flat workpiece surface is obtained by electroplating first, then chemical nickel and phosphorus plating is conducted, and the aluminum wire welding bonding strength can be greatly improved; and meanwhile, because a nickel and phosphorus plating layer has a friendly pasting propertyon both stainless steel and aluminum, the problems that resistance is increased, circuit loss is increased and the bond strength is lowered due to direct contact of a workpiece metal layer and an aluminum wire are solved, meanwhile, the efficiency and the quality are improved, and the cost is reduced.
