EMC considerations for PCB design

In practical EMI shielding, the electromagnetic shielding efficiency depends largely on the physical structure of the chassis, namely, the continuity of conduction. The seams and openings in the chassis are leakage sources of electromagnetic waves.

How to consider safe spacing in PCB design?

Here, it is temporarily classified into two categories: one is electrical related safety spacing, one is non-electrical related safety spacing.

PCB design and analysis of non-isolated IC controller system

Our electronic products are often more than 60% - reliability problems are in the PCB design of the electronic circuit board; Relevant theoretical and practical experience is required for working and performing PCBS;

Correct schematics do not necessarily result in correct PCB designs

In the high-speed era, the ideal wiring on any section of schematic diagram has become an unsatisfactory wiring on PCB, bringing a variety of unexpected high-speed problems. Therefore, PCB engineers also need to accumulate experience and theoretical knowl

Technical analysis: Ten golden principles of PCB design

For circuits with large redundancy of power pins, the number of matched capacitors can also be calculated according to the number of output pins, and every 5 outputs is matched with a 100nf filter capacitor.

How to avoid PCB design risk

The above conclusions are similar when the power source ground distance is less than 10mil. However, when the power source is located at 20mil or even 50mil, the situation changes slightly. As shown in Figure 3, when the ground distance of the power suppl

The installation of decoupling capacitor and PCB design

In the typical radiation case of EMC testing and rectification, common-mode voltage parasitic between analog circuit and digital circuit is the main reason for the formation of common-mode radiation.

Why does the step area on the board after welding bubble in PCB design?

thanks to a deep control area and copper plating on the board, produced a bizarre scene during welding, where the board bubbled in layers. Is the processing of the design, or ignoring the welding process, please see today's case analysis.

PCB design: visual signal eye map, attenuation know well

High-speed public number are engaged in high-speed PCB design (Layout) of the small partner, signal processing theory may not help these friends in their daily work is not too much, these friends may pay more attention to the topic related to wiring.

PCB design consideration for EMI problem and sharing of grounding shielding filter

Another common problem with EMI generation when PCB wiring is changing the reference plane layer without specifying a closed physical path for the signal PCB routing of the return current.

PCB design Tips: Teach you how to quickly make a circuit board

the traditional physical plate making method is labor-intensive, time-consuming and has low precision, while the chemical rapid plate making method has a controllable precision, but the process is complicated and unfavorable to environmental protection. B

Over the "high wall" PCB design engineers no longer "worry"

whether considering from market demand or enterprise development, it is particularly important for PCB system design engineers to complete the design and timely delivery with low cost, fast and efficient.

Just upload Gerber files, BOM files and design files, and the KINGFORD team will provide a complete quotation within 24h.
