The exponential spread of digital equipment such as computers, mobile telecommunications equipment, and digital home appliances has resulted in a radical change in the demand structure for printed circuit boards. In particular, there has been a significant increase in the market shares of MCM module boards, BGA and CSP packages, and multilayer high-density boards represented by build-up boards.
As advances in electronic information technology continue to accelerate, the need for smaller, lighter, and more densely packed electronic components is also rising sharply. This in turn is increasing the demand for laser plotters, which are used for PWB manufacturing equipment, with upgraded precision, quality, and productivity.
To meet these needs, Dainippon Screen has developed the new RG-8000/8500 series of external-drum laser plotters, systems that provide greatly increased productivity compared to previous model. They are designed to receive data from CAD/CAM systems, rasterize it at high-speed, and then output at high-speed with high-precision patterns using our unique multi-channel array of laser beams. The RG-8000 is an economy model specially suited for build-up and multilayer boards. The RG-8500 is a high-end model designed for creating the high-precision masks required for BGA, CSP, and similar packages. Both models offer improved operability with touchpanel operation, and both are Internet-enabled so that managing and operating these laser plotters--even from remote locations--is as easy as using an ordinary office printer.
FEATURES
1. Easy importing of RS-274x,ODB++,Gerber base formats is possible with the CI-7000 integrated CAM system. This also allows creation of layout information on CAD/CAM systems.
2. Quantization errors that could arise after data format conversion are reduced by computing plotting date in units of 0.01 um. This makes it possible to reproduce highly accurate images using the CAD data.
3. High-speed output with optimum plotting precision is possible for each plotting pattern.(10um beam dia./10um beam dia./10um pitch, 10umbeam dia./5um pitch, 10um beam dia./2.5um pitch)
4. Speeding up the film transport system and the adoption of a new lading mechanism achieves a high-performance dimensional stability without applying any stress to the film.
5. A super-precision drum is achieved with improvements in the recording drum process method.
6. Initial costs and running costs are kept to a minimum by long-life semiconductor lasers featuring low power consumption.
7. Waiting time in the output section is eliminated by using the vector file areas to convert up to four data files in parallel with plotting.
