晶体三极管是电子设备的主要元件,其质量的好坏直接影响电子设备整机的稳定性和可靠性。因此,在电子设备的整机生产之前必须对晶体三极管进行筛选,其中对晶体三极管进行功率老化是筛选晶体三极管的一项重要的工艺。要对大批量的晶体三极管进行功率老化筛选,采用一般的人工老化设备是远远不能 Transistor is the main component of electronic equipment, the quality of a direct impact on the quality of electronic equipment, machine stability and reliability. Therefore, before the whole production of electronic equipment, the transistor must be screened, among which the power aging of the transistor is an important process to screen the transistor. To large quantities of transistor power aging screening, the use of artificial aging equipment is far can not
