查询词典 laying top

The invention relates to a method for preventing a top metal layer of packaging chips from fracturing under high temperature, which avoids the fracture of the top metal layer caused by the inter-diffusion of a gold ball, an aluminum welding pad and a top layer metal by introducing a lower metal layer to the joint between the top layer wire and the aluminum welding pad and driving a metal plug to the joint between the top metal layer and the lower metal layer and a metal plug to the joint between the lower metal layer and the aluminum welding pad.

一种防止封装芯片上的顶层金属层在高温下断裂的方法，通过在顶层金属线和铝焊垫之间连接处引入下层金属层，并在顶层金属层和下层金属层之间的连接处以及下层金属层和铝焊垫之间的连接处打金属插塞，避免了因金球、铝焊垫以及顶层金属相互扩散造成的顶层金属层断裂。

It is important to reduce the span of the hard roof to avoid its impact load on supports. However, at longwall top coal caving face, the periodical weight of roof is a main factor that crushes the top coal, which is beneficial to the top coal recovery. How to use the roof pressure safely is of crucial importance in top coal caving. Based on field monitoring, theoretical analysis of strata movement, the numerical model of compound structure of hard roof stepped cantilever and the top coal cantilever beam is built, and the parameters of the model are also determined. The elasto-plastic finite element method is used to analyze the effect of hard coal fracture under the abutment pressure of hard roof, and the cracking coefficient is defined according to the stress state of the element.

通过对岩层移动的现场观测，建立了&两硬&条件综放采场台阶悬臂—悬臂梁组合的煤岩组合结构力学模型，并以此煤岩结构为基础，建立&两硬&条件综放采场顶煤压裂的有限元数值模型，分析了坚硬顶板不同来压步距对坚硬顶煤的压裂效应，并确定了合理的支架阻力，从而对坚硬顶板进行有效的控制，消除坚硬项板对采场的冲击隐患，同时保证采场矿压对坚硬顶煤的有效压裂，达到提高顶煤回收率之目的，由此形成了坚硬顶煤、坚硬顶板条件下综放采场围岩控制的基本理论和方法。
