The Introduction to USB Type-C Pin Signal and PCB Layout03 December 2021
Hello everyone. Welcome to the new post today. USB Type-C is a smaller-volume USB interface standard than Type-A and Type-B. It can be used on a PC (master device) as well as external devices (slave devices, such as mobile phones).
Schottky Diodes: Principle, Functions, and Applications21 October 2025
Schottky diodes are metal-semiconductor devices made of precious metals (gold, silver, aluminum, platinum, etc.) A as the positive electrode and N-type semiconductor B as the negative electrode. Schottky diodes are unidirectionally conductive and can convert alternating currents into pulsed direct currents in a single direction.
Semiconductor Materials:Types, Properties and Production Process21 October 2025
The semiconductor material is a kind of electronic materials with semiconductor properties and can be used to make semiconductor devices and integrated circuits. Various external factors such as light, heat, magnetism, and electricity will act on semiconductors and arouse some physical effects and phenomena, which can be referred to as the semiconductor properties. The majority of the base materials constituting solid-state electronic devices are semiconductors. Different types of semiconductor devices have different functions and characteristics because of the various semiconductor properties.

How are Integrated Circuits produced?20 October 2025
An integrated circuit is a miniature electronic device or component with specific circuit functions. It is made through semiconductor manufacturing processes such as oxidation, photolithography, diffusion, epitaxy, and aluminum evaporation.
Microwave Diode: Introduction and Types07 January 2021
Microwave diodes are diodes that work in the microwave frequency band. It is a solid-state microwave device. Microwave band usually refers to the frequency from 300 MHz to 3000 GHz. After the discovery of the point contact diode effect at the end of the 19th century, microwave diodes such as PIN diodes, varactor diodes, and Schottky diode tubes appeared one after another. Microwave diodes have the advantages of small size and high reliability, and are used in microwave oscillation, amplification, frequency conversion, switching, phase shifting and modulation.
Understanding the Low Noise Amplifier (LNA)20 March 2025
A low noise amplifier is an amplifier with a very low noise figure. It is generally used as a high-frequency or intermediate-frequency preamplifier for various types of radio receivers, as well as amplifying circuits for high-sensitivity electronic detection equipment.

Understanding of Carbon Film Resistors17 October 2025
A carbon film resistor is a type of film resistor, which is also called thermal decomposition carbon film resistor. It’s a thin-film resistor in which the carbon that is thermally decomposed from a hydrocarbon at high temperatures is deposited on a substrate. It adopts high-temperature vacuum coating technology to tightly attach carbon to the surface of a porcelain rod to form a carbon film, and coats the surface with an epoxy resin to protect the film. Its surface is often coated with green protective paint. The thickness of the carbon film determines the resistance value. And usually, the thickness of the film and the groove are used to control the resistor. Besides, it has a low price, stable performance, a wide range of resistance and power.
