从62年至72年,经过十年的努力.人们发明了改性环氧树脂,并解决了半导体器件表面钝化技术,使塑封器件得到飞跃的发展,目前它以上百亿的产量畅销市场,应用范围从单纯的消费品扩大到各种工业,甚至个别军用设备.近几年来,我国的塑封器件也获得了相应的发展,但在产量、质量、价格和可靠性等方面与国外差距较大,现就82年度全国质量评比的塑封小功率晶体管[NPN平面型高频小功率晶体管3DG201(202)B](简称国产管)和日本日电公司同类产品9011GIXD(简称国外管)进行全面的比较.
From 62 to 72 years, after ten years of hard work, people invented the modified epoxy resin and solved the passivation technology of the surface of the semiconductor device, which made the leap development of the plastic sealing device. At present, it produces more than 10 billions of best-selling markets, Applications range from simple consumer goods to various industries, and even individual military equipment.In recent years, China's plastic seal devices have also been the corresponding development, but in terms of output, quality, price and reliability of the gap with foreign countries, Now on the 82 annual national quality appraisal of plastic low-power transistors [NPN planar high-frequency low-power transistors 3DG201 (202) B] (referred to as the domestic tube) and Japan's Nippon Electric 9011GIXD similar products (foreign tube) for a comprehensive comparison.
