1998年是电子元件和光电器件发展的一年。个人电子产品和手持电话的体积不断缩小,促进了设计的不断发展和对高品质图象的要求。人们希望尺寸更小、显示更明亮的图像显示器展示比从前更详细的信息。由于对印刷电路板也同样要求减小尺寸,因而有了能集成多种功能的电子元件,使设计出尺寸更小和功能更多的印刷电路板成为可能。 手持电话的 1998 is a year of development of electronic components and optoelectronic devices. The shrinking volume of personal electronic products and handsets has led to the development of designs and the demand for high-quality graphics. People want smaller, brighter displays that show more detailed information than ever before. As printed circuit boards also require reduced size, electronic components that integrate multiple functions make it possible to design smaller and more versatile printed circuit boards.
