我厂500A硅整流管已投入小批量生产,以投片计,成品率在60％以上,其中大多数管芯的测试电压在1500伏以上,少数可达2500～3000伏。 整个产品的工艺基本上与2CZ200A的一样,因此在本文中不予全面介绍,可参阅我厂1971年9月和1972年4月“关于提高200A硅整流管质量的体会”一文。为了及时交流情况,我们对这次试制工作中的问题及解决问题的一些办法,加以总结,供同志们参考。 Our factory 500A silicon rectifier has been put into small batch production, with the vote meter, the yield of more than 60%, most of the test voltage of the die in 1500 volts or more, a few up to 2500 ~ 3000 volts. The entire product process is basically the same as 2CZ200A, so this article will not be fully described, please refer to our factory in September 1971 and April 1972 “to improve the quality of 200A silicon rectifier tube,” a text. In order to exchange information on a timely manner, we summed up the problems in the trial production and some solutions to the problems so that they can be used for reference by our comrades.
