Technical article - The cause of PCB board hole plugging
At present, our company through a large number of experiments, choose different types of ink and viscosity, adjust the pressure of screen printing, basically solve the hole hole and uneven, has adopted this process for mass production.
Recent development trend of PCB technology in electronic field
The domestic leading automobile board represented by Shanghai Electric Company has actively participated in international cooperation and introduced advanced technology. The high-frequency PCB used for millimeter wave radar has been mass-produced.
PCB through hole technology is fully introduced
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 applications in renewable energy industries such as solar and wind power
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 those

How does SMT plant guarantee PCBA processing quality?
pcba aging test standards: 1, low temperature work, 2, high temperature work, 3, high temperature and high humidity work
Printed circuit board (PCB) selective welding technology detailed
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.
PCB industry prosperity is improving
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
Dry goods PCB copper must pay attention to, otherwise do not cover copper!
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...
What is the prospect of PCB export in China
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.
The PCB routing density is increasing
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
