1、 Circuit board layout design steps Generally speaking, the basic process of layout design can be divided into three steps. (1) Design of circuit schematic diagram The design of circuit schematic diagram is mainly based on PROTEL099′ s Advanced Schematic system to draw a circuit schematic diagram. In this process, we should make full use […]

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. […]

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 beginners draw PCB, they should compare the above basic principles one by one while wiring. After wiring is completed, they should check this rule again. Over time, it will work. The ancients said, “It’s hard to walk.” After all, there are few talented people in the world. Only by persevering can we achieve results. […]

PCB multilayer circuit boards are usually defined as 10-20 or more advanced multilayer circuit boards, which are more difficult to process than traditional multilayer circuit boards and require high quality and reliability. Mainly used in communication equipment, high-end servers, medical electronics, aviation, industrial control, military and other fields. In recent years, the market demand of […]

It is an extremely important part of PCB layout design outsourcing, which will directly affect the performance of PCB. In the process of layout design, different layout engineers have their own understanding of layout, but all layout engineers are consistent in how to improve the efficiency of wiring, which can not only save the development […]

With the continuous development of the electronic industry, the demand for pcb board is also increasing. Common surface processes of pcb board include spraying tin, depositing gold, gold plating, OSP, etc. In fact, spraying tin can be divided into lead-free spraying tin and lead-based spraying tin. Here’s a small sample of pcb proofing to introduce […]

At present, many people think that the pcb multi-layer board making process is super complicated and difficult to understand, but what should I do if I don’t know what I need to do and I can’t learn? Today, let Xiaobian make it easy for you to get tips for making multilayer pcb. Don’t think how […]

The innovation of high-precision high-frequency circuit board rapid proofing printed circuit lies first in the innovation of PCB products and market. The earliest PCB product is a single panel, with only one layer of conductor on the insulation board, and the line width is measured in millimeters, which is commercially used in semiconductor (transistor) radios. […]

Underfilling of pcb is a technology that is often used in electronic industry. In order to meet some special dispensing requirements, the initial underfilling technology of pcb is to meet the production of ceramics. With the development of technology, it is gradually applied to chip packaging of PCB, and then the chip is glued to […]
