设计了一种动态测试与校准系统,并试制了一部分。该系统能够高速测试和激光微调电子组件。为测试器鉴定而选择的电路是M732引信的振荡器和放大器组件。本方案的目标要求是:除机械装卸外,以平均每小时3000套的测试和微调速率把每个选择组件的临界特性调到±0.5%的范围。该系统是为了测量修改后的放大器组件的基本特性,计算炸高和自动激光微调厚膜电阻器,把电阻器参数调到一精确数值而设计的。振荡器组件的灵敏度是通过微调两个陶瓷片式电容器中的一个来调整的。炸高(或灵敏度)是应用一“吸收箱”等效电路或表示各个测试状态的电路模型的组合来进行实时计算的。在需要十分复杂而费时的运算场合,引用了预算查表。工程努力是在系统测试本项目放大器测试部分前结束的。测试系统和硬件设计与制造也完成。现已制造了3000个放大器和75个原型振荡器,并对此进行了电性能检测。基本技术可应用于经过适当修改的其它组件。
Design a dynamic test and calibration system, and trial part. The system is capable of high-speed testing and laser trimming of electronic components. The circuit chosen for tester qualification is the oscillator and amplifier components of the M732 Fuse. The goal of this program is to: Adjust the critical characteristics of each selected component to a range of ± 0.5% at an average of 3000 tests and fine-tuning rates per hour, except for mechanical handling. The system was designed to measure the basic characteristics of a modified amplifier assembly, calculate the height and height of an automatic laser trimmer thick film resistor, and set the resistor parameters to an exact value. The sensitivity of the oscillator components is tuned by fine-tuning one of the two ceramic chip capacitors. Explosion (or sensitivity) is calculated in real time using a combination of “Absorption Box” equivalent circuits or circuit models that represent individual test conditions. Budget lookups are cited in complex and time-consuming operations. Engineering efforts ended before systematically testing the amplifier test section of this project. Test system and hardware design and manufacturing are also completed. There are now manufactured 3000 amplifiers and 75 prototype oscillators, and conducted electrical performance testing. The basic technology can be applied to other components with appropriate modifications.
