In particular, it should be noted that the bypass capacitor needs to pass through two holes when connecting the power layer to the formation, so that the parasitic inductance of the hole will be multiplied.
PCB Assembly, PCB Manufacturing and prototyping The technology used in PCB production has been greatly modified in order to maintain quality and durability with zero defect mass production.
SMT processing materials on the PCBA welding quality of the impact of the following: 1, the impact of components, 2, PCB, 3, the impact of solder paste
pcba aging test standards: 1, low temperature work, 2, high temperature work, 3, high temperature and high humidity work
Compared with the dip welding process, the motion of solder solution and PCB board in the drag welding process makes the thermal conversion efficiency better than that in the dip welding process.
The size of the welding nozzle should be as large as possible to ensure the stability of the welding process and not affect the adjacent components on the PCB, which is important to the design engineer, but also difficult, because the stability of the pro
The grounding isolation belt near the crystal oscillator must be well grounded. In a word: the copper coating on PCB, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line back...
PCB is the mother of electronic products. As long as the electronics industry continues to develop, there will always be business opportunities, and if it can survive the trough, it will meet the peak.
With the development of large-scale integrated circuit and super-large scale integrated circuit, the multilayer printed board (PCB) will be used more and more. In modern electronic systems, with the increase of clock frequency and chip integration, the ra
it is generally sufficient to handle high end harmonics and keep the transient signal low enough, that is, common-mode EMI can be dropped very low. The PCB layer-stack design example presented in this paper will assume layer spacing of 3 to 6mil.
One end of the triangle is connected to a signal wire and the other is connected to ground. When static electricity is present, a tip discharge is generated which consumes electrical energy.
Now PCB design time is shorter and shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large size components make designers
