In PCB design, sometimes we will encounter some single-sided boards, that is, the usual single-sided boards (LED-type light boards are more often designed). In this type of board, only single-sided wiring can be used, so jumpers have to be used. Of course, in complex boards, problems that can be solved with jumpers are basically not…
The water vapor film on the uncoated printed circuit board also provides favorable conditions for the growth and corrosion of the metal. Other common adverse effects include reducing the dielectric strength of the medium and affecting high-frequency signals. What kind of coating material does the PCB manufacturer use? What are the precautions? Dust, stains and…
Sometimes, the distinction between what is considered a “slow” or “fast” signal can seem arbitrary and can depend on who you ask. A related topic is whether a PCB trace is electrically “short” or “long,” and you’ll likely find just as much disagreement on that topic. Whether you need to route slow or fast signals…
Before the emergence of PCB, circuits were made up of point-to-point wiring. This method has low reliability because as the circuit ages, the rupture of the line will cause the circuit node to be broken or short-circuited. Winding technology is a major advancement in circuit technology. This method improves the durability and replaceability of the…
Abstract With the rapid development of high-density interconnect (HDI) and multilayer printed circuit boards (PCBs), the inspection of thick-dense PCBs has become increasingly challenging. Traditional optical inspection methods often fail to provide sufficient illumination uniformity and contrast for detecting defects in thick and densely packed PCB layers. This paper presents a specialized LED lighting system…

Every time the serial data rate increases, it exposes problems that are masked at lower speeds. Many of these problems are caused by the degradation of signal integrity caused by losses in PCB traces, vias, and connectors. Although there are many solutions to signal integrity problems, each solution has its own disadvantages. One response to…
