The circuit board of inverter mainly includes power board, control board, drive board and panel. A, resistance Resistance in the circuit boards with the letter "R" said, the unit has: ohm (Ω), qian Ω (K), megohm Ω (M) Resistance symbol means: 1. According to the characteristics of resistance value, it can be divided into fixed [...]
PCB circuit boards, also called printed circuit boards, printed circuit board, is an important electronic components, electronic components to support the body, is the carrier of electronic electrical connection, with insulating board base material, cut into a certain size, with at least one conductive graphics, and cloth have a hole (such as component hole, fastening [...]
Circuit board of the issues that need to be from the brazing technology, brazing adopts the liquidus temperature is lower than the base solidus temperature of solder metal materials, components and solder will be heated to melt solder, using liquid solder wetting parent metal, filling and joint clearance with parent metal dissolution and diffusion, and [...]
Childhood believe that we have played the kind of game shown in the picture below, small make up to parents to several times in childhood, just bought a game! Although now think it play very single, but it is we can not go back to the good memories of childhood! console This kind of game [...]
In order to ensure the quality of the appearance of the circuit board and, the surface of the circuit board PCB assembly have high request for smoothness, high flatness, fine lines, high precision of the circuit board baseplate surface defect is strict, especially for substrate flatness requirement is more strict, SMB warp degree requirements of [...]
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, [...]
