摘要
提出了一种可以在试验台上进行无条件的筛选、或对已装机而又存在某种隐患的功率管进行老炼筛选的方法,并介绍了如何进行老炼筛选应力的确定和控制,以及试验的过程检测和故障处理。通过理论分析和试验证明,这种方法是切实可行的,能达到老炼筛选的预期目标。
A burn-in screening method that can be performed unconditionally on the test bed or performed on the power tubes that has been installed in system but has some latent flaws. The determination and control of stresses for burn-in screening, testing during burn-in and failure treatment are present. Based on the theoretical analysis and the experimental proof, this method is demonstrated to be practical and feasible, and can achieve expected target for burn-in screenting.
