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。

We can produce any different pitch blade according to customer needs, the classic value of the pitch: A, 10 degree, suitable brush motor FP helichoper, let lower speeds rotor greater lift; B, 8 degree, suitable brushless motor FP helichoper, can make the main rotor get a higher speed; C, 6.5 degrees, suitable some DIY FP helichoper, can make the helicopter have better lock tail performance with a small diameter and high-speed tail rotor.

桨距可以根据客户需要进行定制，经典的桨距值为：A、10度，适合有刷马达的FP电直，能够在较低的转速下取得更大的升力；B、8度，适合无刷马达的FP电直，能够使主桨获得更高的转速；C、6.5度，适合玩家DIY的FP电直，配合小直径高转速的尾桨，能够获得更好的锁尾表现。

The results indicate that weight factor had significantly effect on gait speed, steps per minute, gait cycle time, the ratio of stance time and swing time, maximal flexion angle of knee joint and the range of motion of elbow joint. Shelf height had significantly effects on hip flexion and elbow ROM. Box size factor had significantly effect on stride length, gait cycle time, the ratio of stance time and swing time, knee joint elbow ROM. For the muscle activity levels with EMG, load weight and shelf height both affected the %MVC significantly. When the subjects carrying a load of 14kg, the muscle activity and the subjective body part discomfort rating are both higher than that of 7kg. The box size had effect on the body part discomfort rating of upper extremity and back. For the kinetic and kinematics analysis, the shelf height around elbow height was better than the other two height levels.

研究结果显示，对步态时间与空间参数而言，重量因子显著影响步速、步频、步态周期时间与站立期摆荡期比值，箱型因子显著影响步长、步态周期时间与站立期摆荡期比值；关节活动度而言，重量显著影响膝关节最大弯曲角度、肘关节屈伸角度范围，高度因子显著影响髋关节前后倾角度、肘关节活动各变项，箱型因子影响膝关节弯曲最大最小值以及肘关节活动各变项，对肌肉活动度而言，重量与高度因子皆显著影响MVC%值，14公斤重者肌肉活动度与主观不舒适程度皆较7公斤者高，箱型因子虽无明显影响肌肉活动度，但是在主观不舒适程度上却明显影响上肢与背部，终点放置高度应设在肘高附近为佳。

The deformation of its surface caused by assembly and gravity will lead to increasing of wave-front distortion.

真空靶室作为高功率激光与物质的作用场所，其设计的准则是要具有高稳定性和小的应力变形。

Adjust the pressure of the impact system steplessly, the strike energy of the hammer will also shift steplessly. When the pressure is higher, the strike energy is higher. When the pressure is lower, the strike energy is lower. Adjust the oil flow of supply pump steplessly, the strike frequency will also shift steplessly. When the flow is more, the strike frequency is higher. When the flow is less, the strike frequency is lower.
