Analyses of the practical adhesion strengths of the metal/polymer interfaces in electronic packaging

There is a plethora of techniques to measure the adhesion strength of metal/polymer interfaces. However, the practical adhesion strength, which is the work done in separating the film from the substrate (or one film from another), is very sensitive to the test methods and the mechanical effects, such as the residual stress, thickness and mechanical properties of the layers, strain rate, and phase angle. Deriving intrinsic-adhesion properties of the interfaces, which are independent of such parameters, from the practical adhesion-strength measurements is a formidable task. In the present work, data from the three commonly used adhesion tests; pull-out, 90°-peel, and T-peel tests are compared with the intrinsic-adhesion properties of the interface, such as the interface-fracture toughness or the interface-fracture energy, and their implications are discussed. Material systems analyzed were Cu-based lead frame/epoxy-molding compound (EMC) and Cu/Cr/polyimide.

溶聚丁苯橡胶聚合溶液粘度的研究

研究了（乙二醇二甲醚、二乙二醇二甲醚）－正丁基锂－抽余油体系地溶聚乙苯橡胶不同聚合时间聚合溶液粘度的变化，发现聚合溶粘度与活性种的活性有关，高温严重破坏活性种的活性，计节剂量是杀死活性种活性的另一因素。同时考察了不同苯乙烯／丁二烯（S／B）体系，正丁基锂引发剂用量对聚合粘影响规律，发现S／B越大，聚合粘度越小，S／B越小，聚合粘度越大，引发剂用量减少，聚合液粘度增大。

基于图像数据库的动态场景生成系统

实现各类目标和背景下动态场景的计算机编辑和生成，首先应对组成动态场景的要素进行分析，即目标，目标运动规律和特殊事件四个要素，然后通过编程由四个模块完成相应功能。目标，背景编辑模块可对目标，背景图像进行各种处理，并对重要特征量进行计算，运动路径模块可指定目标的运行规律，包括路线，大小和角度变化等。特殊事件模块可加入独立目标的各类典型事件，如运动的干扰物等。最后通过动态场景合成由计算机自动生成所需的动态场景图像。所需的原始目标，背景图像来源于图像数据库管理系统，通过索引项可便携地找到。     

Thermal—Mechanical Fatigue Behavior and Life Analysis of Cast Ni—base Superalloy K417

In-phase(IP) and out-of-phase(OP)thermal-mechanical fatigue(TMF) behavior of cast Ni-base superalloy K417 was studied.All experiments were carried out under total strain control with temperature cycling between 400-850℃.Both in-phase and out-of-phase TMF specimens exhibited cyclic hardening followed by cyclic softening at the minimum temperature.Besides,they cyclically hardened in the early stage of life followed by cyclic softening at the minimum temperature.Besides,they cyclically hardened in the early stage of life followed by cyclic softening at the maximum temperature.OP TMF life was longer than of IP TMF.Various damage mechanisms operating in different controlled strain ranges and phasing were discussed.A few life prediction methods for isothermal fatigue were used to handle TMF fatigue and their applicability to superalloy K417 was evaluated.The SEM analysis of the fracture surface showed that transgranular fracture was the principal cracking mode for both IP and OP TMF.Oxidation was the main damage mechanism in causing shorter fatigue life for IP TMF compared with OP TMF.
