Capacitor fault The fault caused by capacitor damage is the highest in electronic equipment, especially the damage of electrolytic capacitor is the most common. The capacitor damage is manifested as: capacity reduction, complete loss of capacity, leakage and short circuit. Capacitors play different roles in the circuit, and the faults caused by them also have [...]
FPC circuit board impedance refers to the parameters of resistance and reactance, which hinder the alternating current. Impedance is usually represented by Z, which is a complex number. The real part is called resistance, and the imaginary part is called reactance. The blocking effect of capacitance on alternating current in circuit is called capacitive reactance. [...]
Three proofing paint brushing Three proofing paint using brushing process is the most convenient and effective way of operation, this way of operation, for some circuit board surface components are more regular, circuit board area is relatively small, it is best on a surface, components distribution can not be too dense, different height, must ensure [...]
This capacitor should be a Y capacitor, which is mainly used to eliminate common mode interference. It is also the capacitance that is respectively bridged between the two power lines and the ground (l-e, N-E), which usually appears in pairs. Based on the limitation of leakage current, the value of Y capacitance should not be [...]
With the rapid development of integrated circuit industry, the demand for PCB circuit board only increases, but the market demand is large. PCB is the so-called printed circuit board, which is the support of electronic components and the indispensable carrier of electronic printing. At the same time, there are many PCB circuit board manufacturers, so [...]
En el proceso de producción de PCB, hay dos tipos principales de equipos de galvanoplastia, uno es la línea de galvanoplastia horizontal, el otro es la línea de galvanoplastia vertical.Estos dos tipos de equipos de galvanoplastia de estructura diferente, principalmente el modo de transporte de la placa de circuito es diferente, la estructura del equipo [...]
Some Huawei mobile phones have started to push the upgrade of Hongmeng OS 2.0 system. According to @ Chang'an digital Jun, a microblog blogger, someone has already received a push from Huawei's harmony OS. According to different models, the size of the update packets received is also different. Some are 2.87 GB, while others are [...]
After a long silence, Intel finally updated its new 11 generation desktop core processor. On the 11th generation mobile terminal, Intel has introduced the iris Xe core graphics card for the processor, with "no plug-in performance" as the core selling point. However, the 11th generation core desktop terminal released yesterday only said nothing about "no [...]
April 27 news: Recently, MediaTek and Ericsson have successfully completed the 5g NR dual connection test, effectively combining the wide coverage of sub-6ghz band and the high-speed characteristics of millimeter wave (mmwave), using a variety of spectrum resources to provide higher network speed and lower delay. This move will be conducive to the promotion of [...]
Earlier this month, the semiconductor industry association of America (SIA) and Boston Consulting Group (BCG) jointly released a research report, through more than 20 charts, to analyze and present the distribution characteristics of global semiconductor supply chain in detail. The 53 page report "strengthening the global semiconductor supply chain in an era of uncertainty" mentioned [...]
