If the height of bump is higher, the radius of bump is smaller, and the thickness of wire , substrate and chip is thicker, the strain of package without underfill is smaller. If the height of bump is shorter, the radius of bump is bigger, the thickness of wire is thinner, and the thickness of substrate and chip is thicker, the strain of package with underfill is smaller.

在应变方面，较高的凸块高度，较小的凸块半径，较厚的线路、基板和晶片厚度将对未填胶构装体有较小的应变值；另外较矮的凸块高度，较大的凸块半径，较薄的线路，较厚的基板和晶片厚度将对填胶构装体有较小的应变值。

At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

拉伸蠕变期间，类立方γ\'相中与施加应力轴垂直的界面受水平切应力，使晶格收缩可排斥较大半径的Al、Ta原子；与应力轴平行的界面受拉伸张应力，使晶格扩张可诱捕较大半径的Al、Ta原子，由此引起的原子偏聚形成γ\'相是自由能降低的过程；其中，较大半径的Al、Ta原子扩散迁移至{100}晶面，形成异类原子结合键及稳定的堆垛方式，是促使γ\'相形成N-型筏状结构的主要原因；而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。

Suppose you are running a car at a constant speed with a constant curvature, if you then keep the steering wheel in the same position and increase the car speed gradually, then if the car wants to run on a circle with a smaller radius the car is said to be oversteering, if it remains on the same radius it is neutral and if the car goes to a wider circle it is understeering (for that speed and curvature!).

假设你以固定的速度沿固定曲率的圆周驾驶车辆，然后你保持方向盘角度不变，逐渐增加车辆的速度，此时车辆行使的半径如果变小，称为转向过度（在这个特定的速度和曲率下！）。这个测试还有不同的做法。
