TRIZ APPLICATION IN DEVICE & MANUFACTURING ELECTROSTATIC DISCHARGE CONTROL
A credit card pager having a casing surrounding a substrate and electronic circuitry mounted on the substrate. An information connection including at least one molded waveguide having a core with a photonic device mounted at one end and a second end of the core being positioned on the substrate to be accessible exterior of the casing so as to communicate optical information signals therethrough.
Dust reduction in an electronic industry through TRIZ methodology
The purpose of this project is to reduce dust in electronics products during assembly process. The used of TRIZ concept will improve the process of assembly qualitatively that eliminating the contradiction problem that occurred during the process of improving process. Multimeter products which is has display was selected as a case study to evaluate the process. TRIZ tools 40 Incentive Principles were used to reduce the dust on the display during assembly process. From the proposed solution idea, the results show that clean bench has been selected to control dust at Assembly 1 station. Therefore, results were compared between before and after implementation of clean bench and it show that increasing of yield thus meet the target of yield. Furthermore, the successful of this case study show that TRIZ can be powerful tool to solve a problem.
An analytical approach to the design of electrodes in high-power, fast-transverse-flow CO2 lasers
Abstract Usually, the design of the electrodes of fast-transverse-flow CO 2 lasers relies more on experimental data than on theoretical analysis. Traditional systems sustain a stable, high-power discharge but the current distribution generates a peaked, non-uniform small-signal-gain pattern. We present a theoretical model suitable for the design of electrodes that achieves a quasi uniform gain distribution. The analysis, based on a two-temperature model and the gas-transport equations, computes the electron density that supports a flat gain pattern. Combining the desired electron density with the electron-balance equations, the model determines the required electric field. The results were used to design a new set of electrodes for a home-made fast transverse flow CO 2 laser. A stable, large volume discharge ( 4 × 8 × 90 cm 3 ) with very good uniformity was obtained. The resulting gain distribution was registered in a bi-dimensional map. The peak gain rose from 1.2 m - 1 , attained with the old electrode set, to 1.6 m - 1 with the new one and the gain showed a homogeneous profile.
