IBC Company is the first company in the world to commercially develop oil sand resources. The founding and business operations of both Abasand and Bitumount plant proved to the world that the technical feasibility and potential vitality of oil sand production with very limited technology research support and capital investment. Although, the business operation faced tremendous challenges and difficulties, the experience and lessons learnt by the private investors such as Fitzsimmons during 1920s and 1930s accumulated precious experience to have allowed today's concrete development of oil sands.

IBC公司是世界上第一家商业开发油砂资源的公司，Abasand和Bitumount工厂的存在和发展，在当时技术研究和资金来源都十分匮乏的背景下，向世人证明了油砂开发的技术可行性和潜在的生命力，尽管他们在这些边远地区的生产经营过程中遇到了许多挫折，但是正是由于Fitzsimmons这些个体投资人在20、30年代的努力尝试，积累下了宝贵而丰富的经验，才会出现今天的油砂开发热潮。

The modal tests of PCB and PCB assembly (free boundary condition and fixed boundary condition) were carried out. The equivalent elastic modulus and damping parameters of PCB can be gained, and the fixed boundary condition of finite element model was also determined. These will help to the following work.Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted.

针对JEDEC标准试件的局限性，提出了设计便于统计学研究焊点可靠性的试验试件的构想，利用有限元模态分析方法确定并验证了用圆形PCB组件替代JEDEC标准试件的可行性；通过一系列模态试验和有限元模态分析，确定了圆形PCB组件的相关试验参数，这不仅为跌落碰撞下PCB组件有限元模拟确定了较为合理准确的有限元模型，而且为正确地评价跌落碰撞下PCB组件的可靠性问题奠定了基础。2。

Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted. It was found in our drop tests that the root cause of lead-free solder joints under drop impact was the combined effect of mechanical shock and PCB bending vibration.
