查询词典 speed bump

In this paper, the bump patterns for flip-chip packages are discussed first, then an experiment is setup to study the dispensing phenomena for different bump patterns, and the CAE software is used to analyze and identify with experiment mutually. From these thorough comparisons and analytical analysis, the existence of channel could slow down the flow, the high density of bump could speed up the flow, and it could avoid the air trap by modified the bump and channel's arrangement on flip-chip package. Then flows in rectangular microchannels driven by capillary force and gravity are discussed; furthermore, the theoretical model of flow in microchannel driven by capillary force and gravity is formulated from the Navier-Stokes equations.

本文首先针对覆晶底部充填进行相关理论推导、实验与模拟，探讨不同凸块配置模型所造成的波前不平滑现象对底部充填流动的影响；即依据相关参数建立模型进行底部充填实验，同时以CAE(Computer-Aided Engineering)模流分析软体进行模拟，在完成理论探讨、实验与模拟分析之后，交叉比较理论、实验与模拟分析结果，归纳出影响底胶充填流动之因素，由结果显示在凸块密集度较高的区域，凸块可以帮助流动，但是在凸块区后方的沟槽区域则因为凸块区所提供之流量不足，所以会造成波前落后的现象，另外藉由修改凸块与沟槽配置的关系，可以有效的控制波前形状的变化情形，避免产生包风现象。

Its principle is use feed pump to put the premixed material into the host milling barrel in which proper mill medium is addedand reasonable designed arc line style blades are installed on the main axis symmetrically.Explosion proof machine transits the energy used for separating and milling to main axis through static electricity proof V tape belt to drive blade rotate in high speed, thus it will offer mill medium with high intensity function which can drive beads do random motion and bump with separated grain to create strong cutting force and then cut the material into ion or dissociation,thereby the material will keep in permanent ultramicron separation state.

其原理是利用送料泵浦将预先已搅拌好的物料送入主机研磨桶内，研磨桶内加入适量的研磨介质，合理设计的弧线型葉片对称地安装在主轴上，防爆電机通过防静電V型皮带把分散和研磨所需的能量传送到主轴上带动分散葉片高速转动，给予研磨介质以高强度的动能，带动珠子无规则运动与被分散物料之颗粒撞击产生强大的剪切力，使物料变为离子或游离子从而达到永久的超细微粒分离状态。

On the basis of the summarization of MCM-Cs main features and its assembly and packaging technologies, the paper puts stress on relatively deepgoing studies in practically advanced MCM-C assembly process technologies as gold ball wire bonding, IC chip gold ball stud bump making, IC flip chip bonding and underfilling, in high reliability MCM-C packaging process technologies as integral LTCC substrate packaging, hermetically metal sealing, and also in the basic technological process of MCM-C assembly and packaging. Later on, it presents the effectively engineering development of two high level actual module products--a high-density monolithic processor system MCM-C , a high-speed data collecting and processing system MCM-C. Lastly, it briefly introduces various common methods of quality inspection and reliability test of MCM-C assembly and packaging in engineering practice.

The dissertation investigates the multilane-to-uniline problem in order to solve the theory problem and technique problem of feeding high speed palletizer with several production lines. The harmony equation of the problem is established with the method of movement tracing according to the thought of unit accumulation and free bumping of materials from different lines. For the random of unit materials forming, a strategy of key assignment is put forward to avoid the bump of materials from different lines.

为了解决采用多条供料线向高速码垛机供料以充分利用高速码垛机的处理能力的理论问题和技术问题，本文从一般的角度研究了多线合一问题，根据料股缓冲的思想和无供料干涉的原则，利用运动追踪的方法建立了多线合一问题的协调方程，由此建立了结构参数之间的相互制约关系，为结构参数的制定提供了理论依据，在随机供料的情况下，由于各线料股的形成具有随机性，为了避免各线之间的干涉，本文提出了一种钥匙分配策略很好地解决了这一问题。
