printed circuit board pcb

基本解释

Low surface insulation resistance (SIR) of a printed circuit board (PCB) can degrade the performance of the circuits on the board considerably.
印制电路板的表面绝缘电阻（SIR）低会大大降低电路板的电路性能。
The modal parameters of the printed circuit board(PCB) were calculated using finite element method, and the weaknesses of PCB were found using effective modal masses and mode shapes.
采用有限元方法对印制电路板进行了模态分析，依据有效模态质量和模态振型分析了振动环境下配制电路板的薄弱环节。
