What is resistance? The resistance of a conductor to an electric current is called the resistance of that conductor. Resistor (usually denoted by “R”) is a physical quantity that in physics indicates the amount of resistance of a conductor to current. The higher the resistance of a conductor, the greater the resistance of the conductor […]
To get the best performance of electronic circuits, the layout of components and the layout of the wire is very important. In order to design a good quality, low cost PCB. The following general principles should be followed. Layout First, consider the size of the PCB size. PCB size is too large, the printed lines […]
Classification by number of floors According to the number of layers of circuit classification: divided into single-sided, double-sided and multilayer boards. Common multilayer boards are generally 4-layer boards or 6-layer boards, complex multilayer boards can reach dozens of layers. PCB boards have the following three main types of division. Single Panel Single-Sided Boards In the […]
pcb characteristics PCBs are being used more and more widely because they have many unique advantages, roughly as follows. Can be densely packed Over the years, the high density of printed boards has been able to evolve accordingly with the increased integration of integrated circuits and advances in mounting technology. High Reliability Through a series […]
Light emitting diodes can also be divided into ordinary monochrome light emitting diodes, high brightness light emitting diodes, ultra-high brightness light emitting diodes, color changing light emitting diodes, flashing light emitting diodes, voltage controlled light emitting diodes, infrared light emitting diodes and negative resistance light emitting diodes. LED control modes are constant current and constant […]
Light-emitting diodes, referred to as LEDs, are made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and others. When the electron and hole complex can radiate visible light, so it can be used to make light-emitting diodes. They are used as indicator lights in circuits and instruments, or to form text or […]
History of Semiconductor Development The discovery of semiconductors can actually be traced back a long time. In 1833, British scientist Faraday, the father of electronics, was the first to discover that the resistance of silver sulfide changes with temperature differently from that of ordinary metals, in general, the resistance of metals increases with temperature, but […]
Inductors are generally composed of a skeleton, windings, shields, encapsulation materials, cores or iron cores, etc. 1, the skeleton skeleton refers to the winding of the coil support. Some of the larger fixed inductors or adjustable inductors (such as oscillation coils, current resistors, etc.), most of the enameled wire (or yarn-wrapped wire) around the skeleton, […]
