DP801的制作与调试在我们对DP801的方框图及简单原理初步了解之后,就可以亲自动手制作了,这样会对DP801有更深的了解,下面具体介绍它的制作与调试。一、DP801的制作 1.检查印刷线路板图1是印刷线路板的顶层板图,元器件就插这个面上,通常称为元件面或称正面。图2是印刷线路板的底层板图,它是印刷线路板的背面,为焊接面。为了保障焊接顺利,首先要仔细检查印刷线路板,检查可分两步进行: (1)检查短路与断路短路是指不该通的邻近印刷线路由于极细的毛刺
DP801 production and commissioning After we first understand the block diagram and simple principle of DP801, you can personally make it, so there will be a deeper understanding of the DP801, the following specific introduction of its production and debugging. First, the DP801 production 1. Check the printed circuit board Figure 1 is the top of the printed circuit board diagram, components inserted on this surface, usually referred to as the component surface or front. Figure 2 is a printed circuit board diagram of the bottom board, which is printed on the back of the circuit board, the welding surface. In order to ensure smooth welding, we must first carefully check the printed circuit board inspection can be carried out in two steps: (1) Check the short circuit and open circuit short circuit is not through the adjacent printed circuit due to the very fine burr
