Example Sentences:

	1.	When the substrate is fr4 , the surface shear stress and normal stress difference is at a low level and near zero during curing process and build up during cooling down because of the mismatch of ctes of silicon and substrate 对于fr4基板，在固化过程中，芯片表面的剪切应力和正应力的值很小，其数值在原点上下很窄的范围内波动。在降温过程中，热膨胀系数的失配随着温度的降低而越来越显著，引起应力的积聚。
	2.	It is found during the cooling down in some local region that the normal stress difference varies from positive to negative and then turns positive again . the stress accumulates rapidly in the followed thermal treatment in this region , where the chip - on - board package tends to fail from 在冷却过程中某些局域正应力差的变化规律为：该差值从正值变到负值再回到正值，呈振荡状态；局域随热循环进行应力将急剧增加，即处于应力相对集中的状态，这样的区域是芯片易于失效的区域。
