PCB has connection functional requirements and needs
It is impossible to predict exactly where PCB surface treatment technology will go in the future. Anyway, to meet customer requirements and protect the environment must be done first!

Study on PCB welding resistance design for PCBA manufacturability
It can be seen that the coordination between welding aid and welding resistance pad design plays a decisive role in improving PCBA manufacturability and welding pass-through rate.
Compared with single-sided and double-sided PCB
There is no limit to the number of layers of multilayer boards. At present, there are more than 100 layers of PCB, and the common ones are four and six layers of boards.
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.
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.
Detail PCB board ESD
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.
5G mobile phone era is coming, PCB has new living water?
5G phones will also bring new opportunities to the printed circuit board market, as Chinese mobile phone giants ZTE and Huawei announced in August that the first 5G phones will be officially sold.
The layout of OC48 card
For the analog part of a mixed-signal PCB and the local CPU core with 2V operating voltage, the "layout before wiring" method is not recommended. For OC48 cards, the part of the DSP analog circuit that contains the analog reference voltage and t...
Methods to prevent the warping of PCB printed boards
The board on which the components are installed is bent after welding, and it is difficult to cut the feet of the components neatly. The board can not be installed into the chassis or machine socket, so the assembly plant encountered the board is also ver
Millimeter wave test method
Thinner circuit materials are commonly used in millimeter wave applications because the higher the frequency, the shorter the wave length and the smaller the circuit size.
Damage analysis and summary of laser coding on PCB materials
The copper roots narrow the line spacing, resulting in the printed board does not meet the requirements of Party A, and may even be rejected. Because the rejection will make the production cost of PCB greatly increased.
The etching process of PCB outer circuit was revealed
The more links there are, the more likely there will be problems. This can be regarded as a very special aspect of the printed circuit production process.
