印刷电路板(Printed Circuit Board，PCB)几乎会出现在每一种电子设备当中。它是所有电子设备的载体，计算机内部到处都有PCB的身影，从主板、显卡、声卡到内存载板、CPU载板再到硬盘控制电路板、光驱控制电路板等。小到日常生活中的家用电器、手机、PDA、数码相机，大到车载电子设备，飞机上使用的航空电子产品、卫星火箭上高可X性电子设备。生活在信息时代的我们天天都在和PCB打交道，身为电脑爱好者的我们又时刻谈论着PCB。但是PCB的是如何制造出来的呢？制造它们的设备是什么样子？尤为重要的是，从哪些方面来评价一块板卡的做工好坏？PCB的实际制造过程是在PCB工厂里完成的，工厂是不管设计的，设计工作由专门的公司进行，它们的设计结果叫做原理图，原理图再由专业的布线公司进行线路图的设计，得到的线路图就被交到PCB工厂制作。工厂的任务就是将工作站中的线路图变成现实中的实物板。
