Rules and skills of PCB layout and wiring for switching power supply

Simple switcher PCB layout guide One of the difficulties in writing notes about PCB layout applications is that the engineer reading the article is not the one who intends to use it. Even designers have made great efforts in electromagnetic field, EMC, EMI, circuit board parasitic effect, line effect, grounding, etc. He is likely to […]

Analysis of common problems in cadence layout and wiring

1. How to build your own component library? After creating a new project, the first step to draw a schematic diagram is to create the library you need, and the tool used is part developer. First, create a directory (such as mylib) to store the component library, and then open cds.lib with WordPad. The definition […]

Four FAQs of PCB layout and wiring design

Should GND and DGND ground planes be separated? The simple answer is: it depends on the situation; The detailed answer is: usually no separation. Because in most cases, separating the ground plane will only increase the inductance of the return current, which brings more harm than good. It can be seen from the formula v […]

Analysis of design method based on PCB multilayer board

PCB multilayer board is a special kind of printed circuit board, its “location” is generally special, for example, PCB multilayer board will exist in the circuit board. This kind of multi-layer board can help the machine conduct all kinds of different lines. Not only that, it can also have the effect of insulation. It will […]

What aspects need to be checked after PCB layout and wiring

When a PCB has completed the layout and wiring, and no error is reported in the connectivity and spacing check, is a PCB completed? The answer, of course, is No. Many beginners, including some experienced engineers, are too short of time, impatient or overconfident, so they often neglect the later inspection. As a result, there […]

Analysis of layout and routing method for mixed signal PCB design

The operation of analog circuit depends on continuously changing current and voltage. The work of digital circuit depends on the detection of high level or low level at the receiving end according to the predefined voltage level or threshold, which is equivalent to judging the “true” or “false” of logic state. There is a “gray” […]
