摘　　要：针对某型通信控制设备印制板线断裂问题,首先从断裂机理和疲劳寿命估算两方面分析了印制板线断裂的原因,接着采用仿真分析的方法找出印制板具有振动放大的薄弱环节,然后通过振动疲劳试验,验证了由于振动产生了放大的交变应力,而其进一步导致印制板线形成了疲劳破坏而断裂,最后从质量管理的角度提出了改进建议,以期能够为通信控制设备的维护与检修积累经验。Aiming at the problem of PCB Line Fracture of certain communication control equipment, theoretical analysis is firstly done from fracture mechanism and estimation of fatigue life, then simulation analysis adopted to find the weak link of vibration amplification for PCB, and then via vibration fatigue test, the amplified alternating stress produced by the vibration is verified, and this very stress leads to PCB line forming the fatigue failure and fracture. Finally from the perspective of quality management, the suggestions for improvement are proposed, with a purpose to accumulate some experience for overhaul and maintenance of the communication control equipment.
