The reasearch is to discussice the relationship between water supply and drainage for plan, implement, improvement and management in leadfram plant. The purpose is to discuss and improve the relationship for below coefficients: equipment capability, manufacture target, efficiency and management of water used and role of manufacture department. The major conclusions in this study: 1. It will affect the whole implement result: the ability, target, technology of enviriment manager in the company. 2.It should be controlled any time on the requirement of manufacturing target ,requirement of hardware ability and drafted the expand plan and preparation in advance. 3.For the target of environment management ,we should use the stable improvement method in quality concerned and rule of law followed. 4. For the mass production is the main purpose for a company, we have to communicat with each departments to build the correct thinking for working impelement. The meaning on management of the conclusion in this study: 1.Yield control is the source of competed vantage on same kind products. 2.The equipment plan effects the management and controller of follow-up operation. 3.The accurate execution of maintain plan and the stuff of operators are the key point that effects the yield. 4.The efficiency of equipment is the key point that effects the cost

­^¤åºK­n¡G In this thesis, a two-step de-embedded techniques was applied to measure the important parameters, ft and fmax , of the heterojunction bipolar transistors(HBTs). The same technique was also used to measure the wide-band S parameters for modeling and evaluating the bump chip carrier(BCC) packages. In the simulation, the Ansoft HFSS simulator was used to calculate the insertion and return losses for some bare and packaged test chips. Comparison between simulated and measured results has been discussed in detail to illustrate the applicability of the HFSS simulator.
