With the development of electronic technology, large-scale and high-precision PCB boards have been widely used, and the mounting density of components on PCB boards is getting higher and higher. Simple single-sided and double-sided wiring can no longer meet the requirements of high-performance circuits, so multilayer PCB boards are needed for wiring. High-frequency circuits tend to […]

The layout of PCB Layout design is described from three aspects: right-angle layout, differential layout and serpentine: I. Layout design right-angle routing (three aspects) The influence of right-angle routing on the signal is mainly reflected in three aspects: first, the corner can be equivalent to the capacitive load on the transmission line, slowing down the […]

At present, there are signs that the frequency of printed circuit board design is increasing. With the increasing data rate, the bandwidth required for data transmission also makes the upper limit of signal frequency reach 1GHz or even higher. Although this high-frequency signal technology is far beyond the scope of millimeter wave technology (30GHz), it […]

After layout, wiring and copper plating, a PCBlayout design is basically completed. In order to ensure that there is no omission or violation of design rules in the process of layout design, the final design verification is needed. Here, the standard of verification and detection is the content of rule setting before PCB design, mainly […]

As a PCB engineer, you must master how to quickly design a successful and excellent PCB with layout, which means that you are on the road to achieve a fast, reliable and professional PCB. This article will discuss some concise (and critical) skills and strategies that are applicable to both novice and veteran PCB designers. […]

Find a pcb design company to do PCB Layout design, and prepare the documents as follows. At least the circuit diagram, structure diagram and parts list (BOM) should be provided as the quotation basis. 1. Circuit diagram: circuit diagram, wiring diagram (Schematic) & Nets List. The format of the circuit diagram can be ORCAD or […]

Myth # 1: Is a signal above GHz rate a high-speed signal? When layout mentions “high-speed signal”, it is necessary to define what “high-speed” is first. Is the signal at MHz rate high-speed or the signal at GHz rate high-speed? Traditional SI theory has a classic definition of “high-speed signal”. Si: signal integrity, that is, […]

When designing PCB with PADS Layout, different colors will be set for each layer for easy viewing. In PADS, the top layer is blue by default, and the bottom layer is red by default, which is the opposite of the default color in Altium Designer. Each layer contains many devices, traces, copper foils, etc. You […]

When designing electronic products, we need to use circuit boards. Circuit boards can be divided into single-panel, double-layer and multi-layer boards according to the number of layers. Generally, double-layer boards are often used. Components can be placed on both sides, and the price is also very cheap. I think ordinary electronic products, industrial control electronics, […]

Printed circuit board (PCB), also called printed circuit board (PCB), is a carrier for all kinds of electronic components to realize regular connection. Let’s take a look at the related content together with the layout Design Xiaobian. PCB layout is a printed circuit board. Printed circuit board (PCB), also called printed circuit board (PCB), is […]
