Abstract In semiconductor packaging, cracked die can result from any mechanical contact with the package during the manufacturing operation including final customer assembly. Depending on the extent of the damage to the device, even a subtle crack on the silicon die can diminish the operability, reliability or specifications of a semiconductor component. Historically, customer returns for cracked die have resulted in intense customer dissatisfaction and high penalties for semiconductor suppliers affecting both the automotive and commercial sectors. Over the years, attempts to model the effects of package impact have been unsuccessful due to the extreme complexity of internal package structures and die geometry. For example, “Probe Drop” studies have generated die cracks, but the technique does not accurately simulate the dynamic forces encountered in semiconductor manufacturing nor does it provide a measure of impact force. Other techniques such as Ball-on-Ring (BOR) and 3-Point-Bend testing are used for silicon strength evaluations. Additionally, a major misconception in the industry is that package damage is a good indicator of internal die damage. With the advent of a proper impacting device and use of a commercial load cell and high speed data converter, the concept of dynamic impact package characterization has conclusively proven to be a reliable technique to accurately measure the actual dynamic impact forces imposed to a packaged semiconductor device during manufacturing and customer assembly. The resulting characterization allows for better understanding of the package susceptibility towards failure as devices shrink in size or when assembly materials or techniques change.

Abstract. One of the advances in information technology that now has changed the outlook and human life, business process and business strategy of an institution is the internet. The internet is a very large networks that connected to computers and serves throughout the world in one centralized network. With the internet we can access data and information anytime and anywhere.    As one provider of high-speed data communications services and the pioneer of the internet network service provider in Indonesia that provides integrated services, as well as one of the pioneer development of internet services that provide extensive services in the building and apply it throughout Indonesia. Indosat ready to seize opportunities for sustainable growth of business spectrum are still sprawling Indonesia.    Therefore, Indosat continues to focus on the development of increased efforts to provide the best service for customers of Indosat. Indosat will continue to develop and expand network coverage and a larger investment that the company will achieve excellence in the field of integrated telecommunications services.    Ranking by region of the IP Providers can be seen by grouping IP Providers, and management over IP Providers prefer to choose providers based on where it orginates as an example for the region of the U.S if it will be preferred providers that come from U.S. providers.With the commencement of the internet network optimization start early in 2008 with the selection of the appropriate IP Upstream Provider criteria, it is up to date according to data obtained from Indosat, seen any significant changes to the cost of purchasing capacity of the IP Upstream.    Based on the data obtained that until Q3 or September 2008, the number of IP Upstream Providers that previously there were 20 to 10 IP Upstream Provider, IP Transit Price total decrease of 11% to the price of IP Transit Price / Mbps there is a decrease of 78%, while from the capacity bandwith an increase of 301% capacity from 2008.

Optical networks are bandwidth efficient networks are used for long haul communication providing seamless data transfer. For high speed data transmission in open space between different satellites, Inter-satellite Optical wireless communication (IsOWC) is widely used .In this paper we have evaluated the performance of IsOWC communication link for high speed data transmission .The performance of the system is evaluated on the basis of qualitative parameters such as Q-factor and BER using optisystem simulator.
