所谓真空晶体镀膜即在真空条件下对石英晶体蒸镀上一层导电膜。通常为铬和银。使其电极形成,被做成各种频率的石英晶体振荡器。 多年来,晶体振荡器被广泛应用于通讯、工业仪表及民用电器中。如低频率的石英晶体振荡器可做成各种钟表、儿童玩具和装饰品等。这些产品不仅畅 The so-called vacuum crystal coating that is vacuum deposition of quartz crystal on a conductive film. Usually chromium and silver. The electrodes are formed and made into quartz crystal oscillators of various frequencies. Over the years, crystal oscillators are widely used in telecommunications, industrial instrumentation and consumer electronics. Such as low-frequency quartz crystal oscillator can be made into a variety of watches, children’s toys and decorations. These products are not only smooth
