First, the failure caused by capacitor damage is the highest in electronic equipment, especially in the electrolytic capacitor damage is the most common. Capacitance damage is shown as: capacity decreases; Total loss of capacity; The leakage; Short circuit. Capacitors play different roles in the circuit and the faults caused by them have their own characteristics. [...]
The specialty is engaged in the electronic product SMT processing welding operator contact every day is printed circuit board, solder and flux related materials, tools, and other work. Therefore, in addition to paying attention to the above electricity safety, operators also need to master the knowledge of this aspect, in order to ensure their safety [...]
We often see the concept of teardrop, but many students do not understand the meaning of the word, let alone how to add teardrop in PCB design. Please look down with this question in mind The effect of tear drops ● when the circuit board is impacted by a huge external force, the wire is [...]
With the rapid development of the electronic technology industry, printed circuit boards (PCBs) have been printed in large quantities and then burned or discarded due to the constant upgrading of electronic products. This not only leads to a large amount of waste of metal and non-metal materials in the circuit board, but also the heavy [...]
In real life, as a girl? Well, nowadays most girls like to call themselves guys... But a failure of electrical appliances in the home but do not know how to start is not a face of cute, especially in the family in the main position of our mother and the future of us, ha ha, [...]
Without further ado, let's begin the installation. The whole process is very simple, just take the old one and replace it with a new one. It is also easy to remove, just need to unscrew a total of eight screws can be. Just saw PS1 handle DIY motherboard set feel some simple design, disassemble the [...]
4. A possible coupling of magnetic field lines, similar to figure 1. To sum up, the cloth board should follow the following principles: Complete grounding should be ensured below the lead. Sensitive leads should be arranged vertically. If leads must be parallel, ensure adequate spacing or use protective wires. Grounding via The main problem with [...]
Then I'll find out why. I'll look at the board. Want to want to go, should be no problem! Then go into meditation and sleep at night thinking about it. The next day, suddenly thought of a problem, FLASH is not as long also have a problem. To solve the problem There's no reason FLASH [...]
[5G commercially opened, communication circuit board is remarkably elastic] PCB circuit board is divided into seven categories by application: communication, computer, consumer electronics, industrial control medical, automotive electronics, aerospace and packaging substrate. Thanks to the construction of 3/4g communication network and the wide application of automotive electronics, the PCB output value in the communication and [...]
There are many ways to solve EMI problems. Modern EMI suppression methods include EMI suppression coating, EMI suppression parts and EMI simulation design, etc. Starting from the most basic PCB layout, this paper discusses the role and design skills of PCB layering and stacking in controlling EMI radiation. Power busbar The jump of IC output [...]
