集成电路元器件管脚成形方法及工艺分析

Forming Method and Process Analysis of the Pins for IC Components

在集成电路元器件生产过程中,元器件管脚的成形是其中的关键工序为了降低成本和提高效率,器件外形越来越小并且封装密度越来越大,相对应的元器件管脚的成形的工艺性越来越苛刻,其中很多前道工序中隐藏的问题也会在管脚成形过程中表现出来从元器件管脚的成形形状设计开始,分析了如何设计一个满足成形工艺需求的管脚形状,以及如何实现管脚的成形.

In the production process of IC components,the forming of component pins is the key process.For the sake of cost and efficiency,the component outline is getting smaller and the package density is getting larger.The forming manufacturability of component pin is more and more rigorous,many of the hidden problems in the previous process will also appear in the pin forming process.This article starts with the design of the shape of the pins of the components,describes how to design a pin shape to meet the requirements of forming process,and how to realize the forming of the pin.
