Flat Welding : choice of welding technology, electrode diameter, welding current, welding speed, the length of arc welding, weld process verification; Welding : welding inspection clearance groove, assembly space whether it meets the requirements, positioning it firmly welding, weld around is not oil, rust; Electrode temperature and baking time should be required, the rod removed from the oven. tempreture-constant drum on the electrode, then used as admission; Latin America : welding supply welding thickness, welding levels and electrode type and diameter, skilled welders and other factors, and to select appropriate welding current; fillet weld arc : fluctuations in the point arc weld end, they are advised more than 10 mm, is not hard arc, sparking arc weld zone from the electrode should be started immediately. Component integration and maintaining so-rod pieces have 2-4 mm gap arc.

1.1.2.1平焊：选择合适的焊接工艺，焊条直径，焊接电流，焊接速度，焊接电弧长度等，通过焊接工艺验证；清理焊口：焊前检查坡口、组装间隙是否符合要求，定位焊是否牢固，焊缝周围不得有油污、锈物；烘焙焊条应符合规定温度与时间，从烘箱中取出的焊条，放在焊条保温桶内，随用随取；焊拉电源：根据焊件厚度、焊接层次、焊条型号、直径、焊工熟练程度等因素，选择适宜的焊接电流；引弧：角焊缝起落弧点应在焊缝端部，宜大于10㎜，不应随便打弧，打火引弧后应立即将焊条从焊缝区拉开，使焊条块结合与构件间保持2～4㎜间隙产生电弧。

For wire bonding,we got methods to avoid low-k material layer crack and IMC crack by gold wire selection,capillary design optimization,and wire bonding process window study;Wire sweep issue was declined,after use reverse wire bonding technology to get low wire loop,define high wire loop and low wire loop between neighbour wires to reduce wire cross and split transfer course into several segments by different transfer speed to control mold flow;For molding and to different packages,as a physical method,add suitable presser during different cure process,it can reduce warpage value;As chemical methods,optimized component of molding compound or added flexiblier,it can decline thermal stress and warpage.

在引线键合方面，通过对不同纯度金线的选择、劈刀设计的优化、以及对引线压焊工艺窗口的研究，找到了可降低焊盘碎裂，金铝间化合物分层等问题的方法；通过使用反向压焊来控制线线弧高度和在邻近线间使用高(来源：A7aB4848C论文网www.abclunwen.com)低线弧来控制线弧以及模塑注塑速度细分化的方法，有效降低了冲线值；在模塑方面，针对不同封装形式，通过封装模块在烘烤过程中优化外加压力的时机，利用物理方法有效减低了翘曲；此外从化学角度出发，通过对模塑材料配方的优化以及添加应力释放剂，有效降低了封装内的热应力，减小了封装模块的翘曲。
