What is difference between TVS tube and zener diode?Archive
Zener Diode A. Principle It works in a reverse voltage breakdown state. When reverse voltage reaches and exceeds a stable voltage, reverse current suddenly increases while voltage across diode remains constant. B. Classification ...
Still foolishly setting silkscreen bit numbers of PCB components one by one?Archive
For subsequent assembly of components, especially manual assembly of components, PCB assembly drawing is usually used to place and position components. At this time, silkscreen position number indicates its need. Friends starting...
Haberdashery｜General failure mechanism and analysis of electronic componentsArchive
The main failure modes of electronic components include, but are not limited to, open circuit, short circuit, fire, explosion, leakage, functional failure, electrical drift, intermittent failure, etc. For iron engineers, failure o...
Explain in detail classification of more than a dozen types of "recommended collection" capacitorsArchive
01 Porcelain Capacitor This capacitor uses a ceramic material as a medium, which covers a layer of metal (silver) film on surface of the ceramic, and then sintered at high temperature as an electrode. Ceramic capacitors are classi...
Six Methods for Testing PCB Short CircuitsArchive
First, let's look at types of common PCB shorts: A short circuit can be divided by function: Solder short (e.g. tin joint), PCB short (e.g. residual copper, hole deflection, etc.), device short, assembly short, ESD/EOS breakdown, ...
Suggested collection: Capacitor filtering analysis and EMC suggestions.Archive
01 Capacitor filtering effect That is, higher frequency f, lower impedance Z of capacitor. At low frequency, due to relatively large impedance Z of capacitor C, useful signal can pass unhindered; At high frequency, capacitance...
Three common grounding methods in circuit designArchive
As we all know, good EMC circuitry goes hand in hand with excellent grounding. This article details three common grounding methods. 1. Land division and connection Grounding is one of important means of suppressing electromagneti...
Easy to understand! Explain PIDArchive
Today I will explain to you what is PID in form of pictures and texts? What is function of each PID parameter? Where will PID be used? Come learn together! What is a PID? The PID (proportional-integral-derivative) controller is ...
What you need to know about semiconductor chipsArchive
Size reduction has physical limitations However, production process cannot be reduced indefinitely. When we reduce size of transistor to about 20 nanometers, we will run into problems in quantum physics that will cause leakage in ...
USB trace layout experience, a painful lessonArchive
USB is a fast, two-way, synchronous, low-cost, easy-to-use, hot-swappable serial interface. Because of advantages of fast data transfer, user-friendly interface, and hot plug support, USB devices are widely used. Currently, most ...
