PCB 行业受需求端主导,呈现周期性波动特征。主要由以下原因导致:PCB 被称为“电子产品之母”,是承载电子元器件并连接电路的桥梁,广泛应用于通信设备、汽车电子、消费电子等终端领域,涉及绝大部分终端电子产品,电子产品需求与宏观经济拟合度较高 ...
PCB,即印制电路板(Printed Circuit Board),是现代电子设备中不可或缺的重要部件。它是电子元器件电气连接的提供者,是电子产品的大脑和心脏,被广泛应用于各种电子设备中。 那么,PCB板究竟是什么意思?它的工作原理和应用场景是什么?本文一一道来。
印制电路板(Printed Circuit Board,简称“PCB”),又称印制线路板、印刷电路板、印刷线路板,是在电路中起固定各种元器件,提供各项元器件之间的连接电路,由绝缘隔热、有一定强度的材质制作而成的板材。广义上讲:是在印刷电路板上搭载LSI、IC、晶体管、电阻 ...
现在但凡打开SoC原厂的pcb Layout Guide,都会提及到高速信号的走线的拐角角度问题,都会说高速信号不要以直角走线,要以45度角走线,并且会说走圆弧会比45度拐角更好。事实是不是这样?PCB走线角度该怎样设置,是走45度好还是走圆弧好?90度直角走线到底行不行 ...
