前言目前,大功率和小体积是电子节能灯的一个发展方向,随着功率密度的提高,对元器件及元器件间的匹配都提出了新的要求。另一方面,产品方方面面的成本都在提升,唯一的办法只能以“工艺为突破口”,来提高产品的质量和合格率,从而降低生产成本和售后服务费用,更好地参与竞争。1元 Preface At present, high power and small size is a development direction of electronic energy-saving lamps, with the improvement of power density, the match between components and components have put forward new requirements. On the other hand, the cost of all aspects of products are rising, the only way to “technology as a breakthrough point” to improve product quality and pass rate, thereby reducing production costs and after-sales service costs, to better participate in the competition. 1 Yuan
