前言随着电子工业的飞速发展在电子技术中对电子管要求也越来越高,(特别是大功率管,特种管)而金属与陶瓷封接质量是保证电子管各项技术参数及正常使用的关键一环。银铜钛合金焊料是近几年我所研制成功的用于金属与陶瓷封接的理想材料。过去在电子管生产中较多采用银铜钛芯焊料及涂钛工艺,但由于 Preface With the rapid development of the electronics industry in the electronic technology requirements of the tube is also getting higher and higher, (especially high-power tube, special tube) and metal and ceramic sealing quality is to ensure the technical parameters of the tube and the key to normal use A ring. Silver copper titanium alloy solder in recent years I developed the successful application of metal and ceramic sealing ideal material. In the past in the tube production more silver-titanium titanium core solder and titanium coating process, but due
