Scientists from misis (NUST misis) and colleagues from the Russian Academy of sciences have jointly created a unique silicon nanocomposite. They believe that this research and development achievement will accelerate the development of "micro power plant" technology directly placed on the printed circuit board of electronic products. The results were published in the journal microporous [...]
The non-metallic powder, also called VT powder, is a kind of thermosetting plastic powder, which is mainly composed of glass fiber and thermosetting resin. It can be used to modify filling materials and waterproof materials. Due to the fact that thermosetting plastics can not be recycled, the VT powder obtained from the recycling of PCB [...]
A complete circuit board contains a large number of electronic components. Because of many uncertain factors, the damage of components is very common. When the equipment failure is mostly caused by the damage of components, then the detection and maintenance of components is very important, how to judge the quality of a component is a [...]
Time base circuit 555 various application circuits The 555 touch timing switch IC 1 is a 555 timing circuit, which is connected to a monostable circuit here. Normally, because there is no induction voltage at the P end of the touch pad, the capacitance C1 is discharged through the 7th foot of 555, the third [...]
