摘要
目前,最常采用的三种电路板固定方式已经无法满足机载设备电路板安装要求。因此,设计了一种新型电路板装夹方法,该方法采用楔形锁紧结构,将印制电路板卡锁在框架卡槽上,抵抗振动和冲击,帮助电子元器件散热,同时还能方便拆装,为后续电路板调试和检修提供条件。
At present, the three most commonly used circuit board fixing methods have been unable to meet the requirements for onboard equipment board installation. Therefore, a new circuit board clamping method is designed. The method uses a wedge-shaped locking structure to lock the printed circuit board on the frame card slot to resist vibration and shock, and to help the electronic components to dissipate heat. Install, provide conditions for subsequent board debugging and maintenance.
