On the morning of August 8, media reported that SMIC was forced to suspend the CIM localization project of its new 12-inch wafer factory in Beijing recently because the project's technical contractor...[Details]
Over the past five years or so, engineers have been focusing more on low-voltage differential signaling to significantly improve system performance. Data rates have increased exponentially, driving t...[Details]
Circuit Function and Advantages
The circuit shown in Figure 1 is capable of monitoring bidirectional currents with less than 1% linearity error on sources with dc voltages up to ±270 V. The lo...[Details]
In a factory, a human-machine interface usually needs to establish communication with multiple PLCs, and the locations of the devices are different. If wiring is required, it needs to be constructe...[Details]
According to LETSGODIGITAL, Samsung recently applied for a very special new patent for a folding phone because this phone will be able to fold inward and outward. Samsung's patent was published ...[Details]
In recent years, with the continuous development of LED lamp packaging technology and heat dissipation technology, the stability of LED lamps has reached a relatively good level. The main causes of...[Details]
As power levels increase and modern power systems become more complex, the demands on high-voltage systems have changed significantly. To effectively meet these demands, it is necessary to us...[Details]
In most modern
control
systems, light-emitting diodes (LEDs), digital tubes, liquid crystal displays, buzzers, etc. are usually used for status/result display and fault alarm. If digital la...[Details]
Driven by faster connections, greater automation, and smarter systems, Industry 4.0 has accelerated the use of vision technology in manufacturing and introduced intelligence into previously simple ...[Details]
We need to pay attention to and consider many rules. For example, the nominal value of a fuse is 1A, which refers to the indicator at 25 degrees, but if the equipment works at 50 degrees, the nominal...[Details]
Some people often simply think that when an isolation transformer is installed in the system, its anti-interference function will be very strong. This understanding is not entirely correct. In th...[Details]
STM32 PWM output Pulse width mode (PWM mode) can be used to generate a signal with a frequency determined by the TIMx_ARR register and a duty cycle determined by the TIMx_CCRx register. In STM32 de...[Details]
