In PCB layout design and wiring, it is required to avoid the situation of right angle wiring as far as possible, which has become one of the standards to measure the quality of wiring, so how much impact will the right angle wiring have on signal transmission? In principle, the right angle wiring designed by […]

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. […]

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 […]

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 […]

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 […]

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 […]

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 […]

Good ingredients for PCB board making are worthy of trust. The speed of hot air motor in reflow oven will directly change the speed of hot air reflow soldering in unit area. Under the influence of hot air speed of reflow soldering on welding quality, the appropriate transportation speed can be adjusted. On the premise […]
