A netizen commented that the same phone, Samsung Note9, saves battery power far more when plugged into the mobile card alone than when plugged into the Unicom card alone. Online, wifi is also used in this case. This IS THE BATTERY LIFE OF THE MOBILE CARD INSERTED YESTERDAY AFTERNOON UNTIL 8:20 AM TODAY. Besides SCROLLING […]
Hardware FITTINGS IS THE SMALL HARDWARE THAT SHOWS METAL TO PASS THE PROGRAM SUCH AS STAMPING TO MAKE AND BECOME, WAIT LIKE GASKET, RIVET, BUTTON. These hardware products are widely used in all walks of life, people's production, life. What are those areas? First, clothing bags The buttons and rivets in the hardware accessories are […]
The semiconductor diode mainly depends on the PN junction and work. The point contact type and Schottky type, which are inseparable from the PN junction, are also included in the range of general diodes. So what types can it be classified according to its construction? Follow Xiaobian to have a look ~ ⒈ Dot contact […]
The Capacitance, also known as the Capacitance, refers to the charge storage at a given potential difference. The symbol is "C". The SI unit is Farad. The commonly used capacitance units are millimetric (mF), micrometric (μF), nanometric (nF) and cuticle (pF). The specific conversion method is as follows: 1 farad (F) =1000 milieu (mF) =1000000 […]

So-called integrated circuit technology, is the transistors, diodes, resistors, capacitors and so on certain process will be needed for the circuit elements such as transistors, diodes, resistors, capacitors, and then use the proper process for interconnection, then encapsulated within the shell, the volume of the whole circuit is greatly reduced, the number of wires and […]
Current sensor, is a kind of detection device, can feel the information of the measured current, and can be detected and feel the information, according to a certain law to meet a certain standard of electrical signal or other required form of information output, in order to meet the transmission, processing, storage, display, recording and […]
The Hardware stamping process can be divided into two categories: hot stamping and cold stamping. Metal stamping hot stamping is to heat metal materials to a certain temperature range of stamping processing method. The characteristics of hot punching are: can eliminate internal stress, avoid work hardening, increase the plasticity of materials, reduce deformation resistance, reduce […]
During communication, there are two causes of terminal resistance signal reflection: impedance discontinuity and impedance mismatch. Impedance discontinuity, the signal at the end of the transmission line suddenly meets the cable impedance is very little or no, the signal will cause reflection at this point. The principle of signal reflection is similar to the way […]
In this day and age, you may not have a watch, but your home must have an electricity meter. The electricity meter, as a measuring instrument related to people's livelihood, is an essential tool for electricity metering and electricity bill settlement. Have you looked closely at your own electricity meter? Does your home use a […]
