ESI introduces embedded passive laser trimming system
Keywords: Electro Scientific industries inc, Printed circuit board
Electro Scientific Industries Inc. have introduced a large platform, embedded passive laser trimming system. As printed circuit board (PCB) manufacturers drive to fit more integrated circuits and passive components into a design without increasing size or compromising performance, laser trimming of embedded passives becomes a key enabling technology. ESI's new system, the Model 4700, allows manufacturers to achieve tighter tolerances and increase functionality by trimming embedding passive components within inner layers of multi- layer PCBs. This in turn accomplishes end-user goals of smaller, lighter and less expensive handheld portable devices.The Model 4700 trims resistors to tolerances of less than one percent in high volume production, enabling manufacturers to readily replace surface mount components without compromising accuracy and quality. The system accommodates panel sizes of up to 24 inches by 30 inches, and incorporates many features for resistor trimming that have been field proven in other industries for over 30 years.
