As we all know, when designing PCB, if it’s just an ordinary board, just do a good job of precise design of mechanical dimensions. However, if high-frequency signals, load lines or long lines are used, these lines should be treated specially; otherwise, a series of signal interference problems, such as reflection and crosstalk between lines, […]

Have seen the PCB (printed circuit board) of radio or computer, are there any interconnected electronic components? No? Then, this is a circuit board containing pads and wires, which can be electrically connected together at different points, or more precisely, connect components and connectors to each other. Circuit boards allow signals and power to be […]

1. It’s too late. I suggest you get your EMS partners involved as soon as possible, preferably when the first draft of your PCB layout is available, and allow yourself enough time for prototype design and trial production. For all the checks you perform on paper or PC, there may be some “functions” that are […]

Pcb sample is the most important step for any electronic hardware design engineer in electronic products, and it is also the beginning of all electronic products. From pcb design to finished electronic products, gadgets, smart phones, home appliances or electrical appliances, and so on, all electronic products and equipment you can think of and see. […]

1. Passive crystal-Passive crystal needs the oscillator on the DSP chip, and the connection method is suggested on the datasheet. Passive crystal has no voltage problem, and the signal level is variable, that is to say, it is determined according to the starting circuit. The same crystal can be applied to various voltages and DSPs […]

1.PCBA production efficiency When you want a large PCB circuit board, many factories may not be able to do it because of its particularity. Therefore, it is necessary to know whether the supplier can produce and what is the production efficiency? When the PCB is larger than the industry standard and the supplier has no […]

The design of radio frequency (RF)PCB has many uncertainties in the published theory, which is often described as a “black art”. Usually, for circuits in the frequency band below microwave (including low-frequency and low-frequency digital circuits), careful planning on the premise of mastering all kinds of design principles is the guarantee of successful design at […]

Generally, the design current of PCB will not exceed 10A or even 5A. Especially in household and consumer electronics, the continuous working current on PCB usually does not exceed 2A. Recently, however, the company’s products should be designed with a power line, and the continuous current can reach about 80A. Considering the instantaneous current and […]

A good PCB layout design can optimize the efficiency, slow down the thermal stress, and minimize the noise and interaction between traces and components. All this comes from the designer’s understanding of the current conduction path and signal flow in the power supply. When a prototype power panel is powered on for the first time, […]

Printed circuit boards can be used in all fields, including motion control applications. The new CAD software can help designers create better schematic diagrams and layouts. Gone are the days when “electricity” and “mechanics” became independent disciplines. Nowadays, almost all mechanical systems are equipped with some form of electronic equipment for monitoring, control or both. […]
