The following content of this article introduces the ten most effective design rules that electronic design engineers should keep in mind and practice when using design software for PCB layout design and commercial manufacturing. Engineers do not need to implement these rules in order of time or relative importance, just following them all can greatly…
The parallel signals and serial signals referred to in this article include the transmission (communication) method, the interface type, and the protocol characteristics of the data itself, signals, protocols, buses and interfaces. If you want to know the difference between signals, protocols, buses and interfaces, you can read the previous article: [size=1em] A brief history…
This article explores PCBA control boards, detailing their structure, functions, and diverse applications in various industries. Learn how these vital components enhance electronic systems, boosting efficiency and reliability.
What is a surge? Surges are called transient overcurrents, which are short-term current and voltage fluctuations in circuits, usually lasting about one millionth of a second in the circuit. A voltage fluctuation of 5,000 or 10,000 volts that lasts for a moment (one millionth of a second) in a 220-volt circuit system is a surge…
With the rapid development of electronic technology, electronic products tend to be miniaturized, complex, and more and more complete in functions. Therefore, for PCB printed circuit boards, they have also developed from the original single-sided board to double-sided boards and multi-layer boards. High precision, high density, high reliability, and miniaturization have become the general trend…
The difference between immersion gold board and gold-plated boardIn the actual trial process, 90% of the gold boards can be replaced by immersion gold board instead of gold-plated board. The poor weldability of gold-plated board is its fatal shortcoming. In the process of use, because of the low conductivity of gold, it is widely used…
Copper coating is a common operation, which is to cover the area without wiring on the circuit board with copper film. This can enhance the anti-interference performance of the circuit board. The so-called copper coating is to use the idle space on the PCB as the reference surface and then fill it with solid copper….
Discover budget-friendly PCB assembly services tailored for your electronics projects. Learn how to save costs without sacrificing quality, ensuring your prototypes and products are assembled efficiently and effectively.
Part 1 PCB wiring In PCB design, wiring is an important step to complete product design. It can be said that the previous preparations are all done for it. In the entire PCB, the design process of wiring is the most demanding, the most skillful, and the most labor-intensive. PCB wiring includes single-sided wiring, double-sided…
Explore the leading PCB fabrication companies renowned for their quality and precision. This article highlights top industry players who excel in producing high-quality printed circuit boards to meet diverse manufacturing needs.
In any switching power supply design, the physical design of the PCB board is the last link. If the design method is not appropriate, the PCB may radiate too much electromagnetic interference, causing the power supply to work unstably. The following is an analysis of the matters that need to be paid attention to in…
(Printedcircuitboard, referred to as PCB) is a substrate for assembling electronic parts. It is a printed board that forms point-to-point connections and printed components on a general substrate according to a predetermined design. The main function of this product is to enable various electronic components to form a predetermined circuit connection, play a role in…
Proofing starts from 5 yuan. Copper clad laminate is the substrate for processing and manufacturing PCB. It is the most important type of material. The manufacturing process of the clad laminate is to impregnate glass fiber cloth, glass fiber felt, paper and other reinforcing materials with epoxy resin, phenolic resin and other adhesives, dry them…
What is gold plating? What we call whole board gold plating generally refers to “electroplating gold”, “electroplating nickel gold board”, “electrolytic gold”, “electro gold”, and “electro nickel gold board”. There is a distinction between soft gold and hard gold (generally hard gold is used for gold fingers). The principle is to dissolve nickel and gold…
1.High heat generation devices plus heat sinks and heat conducting plates When there are a few devices on the PCB that generate a lot of heat (less than 3), a heat sink or heat pipe can be added to the heat generating device. When the temperature cannot be lowered, a heat sink with a fan…
