For the aged aluminum alloys which generally contain disc/plate-shaped or rod/needle-shaped precipitates, a model has been established, from the viewpoints of thermodynamics, kinetics and strengthening theory, to relate quantitatively the yield strength to the size, volume fraction and aspect ratio of precipitates which all were analytical associated with the chemical compositions of alloys, aging temperature and aging time. This model has been experimentally proved to well predict the variation of yield strength with the evolution of disc/plate-shaped or rod/needle-shaped precipitates for present Al-4. 62wt% Cu-0.65wt% Mg alloy aged at 513K and Al-1. 12wt% Mg0.57wt% Si alloy aged at 463K, respectively, and the yield strengths simulated by this model were also found to be in well agreement with previously measured values for a series of aged Al-Cu binary alloys, AA6061 and Al-Zn-Mg alloys.

Encapsulant was driven by capillary force into the space between the chip and substrate. Underfill technique can protect the electrical device and prevent the device from destroying because of external force. Underfill has many defects including the fill time is too long, the situation of short shot and air trap are caused easily, the yield of product of Flip-Chip is not highest and the products are universal. Therefore, there are many factors being studied in this paper to sum up the influence of underfill of Flip-Chip process cause by model parameters.
覆晶接合技术为先进电子讯号连接技术中的一种,具有高I/O数、电子讯号路径短以及尺寸小等优点,而采用覆晶接合之电子元件大部分均以底部充填技术进行封装;底部充填是一种以毛细作用为驱动力在晶片与基板之间的间隙充填底胶的封装技术,可以确保晶片不受到外力的影响而损及封装体,但此技术具有充填时间长、容易产生短射与包风等缺点,使得覆晶封装制程良率不高,间接影响覆晶封装产品的普及率,因此本文将依各种可能之参数模型对覆晶封装底部充填制程的影响,以供业界参考。
