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 […]

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 […]

As the most general analog device, operational amplifier is widely used in signal conversion and conditioning, ADC sampling front end, power supply circuit and other occasions. Although the peripheral circuit of the operational amplifier is simple, there are still many points needing attention in the use process. 1. Pay attention to whether the input voltage […]

In PCB design, whether to use SMD magnetic beads or SMD inductors mainly focuses on the application scenario. Design pcb The design of printed circuit board is based on the circuit schematic diagram to realize the functions required by circuit designers. The design of printed circuit board mainly refers to layout design, and the layout […]

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, […]

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 […]

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 […]

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, […]

ESD is what we often call Electro-Stac discharge. From the learned knowledge, we can know that static electricity is a natural phenomenon, which is usually generated by contact, friction, induction between electrical appliances, etc. It is characterized by long-term accumulation, high voltage (which can generate thousands or even tens of thousands of volts of static […]

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 […]
