大家都知道理做PCB板就是把设计好的原理图变成一块实实在在的PCB电路板,请别小看这一过程,有很多原理上行得通的东西在工程中却难以实现,或是别人能实现的东西另一些人却实现不了,因此说做一块PCB板不难,但要做好一块PCB板却不是一件容易的事情 -PCB logic board大家都知to do is to design a good schematic of the PCB into a real circuit board, do not look down on this process, there are many things to work on the principle in engineering is difficult to achieve, or others to achieve things that other people fail to realize, so that it is not difficult to do a piece of PCB board, but to do a piece of PCB board is not an easy thing
