The layout should be noted
The key of RF circuit PCB design is how to reduce the radiation ability and how to improve the anti-interference ability, reasonable layout and wiring is the guarantee of the design of RF circuit PCB.
Is there a difference between gold plating and silver plating on PCB?
Even if the oxidation after a long time of use will almost only occur in the insertion and removal of the connection part, and there is no impact on the welding pad and the welded components.
The occurrence of cavity in PCB hole wall coating and its countermeasures
There are many factors causing the coating cavity, the most common is PTH coating cavity, by controlling the relevant process parameters of the potion can effectively reduce the generation of PTH coating cavity.
Rigid deflection of printed circuit board to drill dirt and dent technology
whether it is dry method or wet method, if suitable method is selected according to the characteristics of the main material of the system, the purpose of drilling and etching of rigid torsion interconnection mother plate can be achieved.
Plasma surface pretreatment in PCB board manufacturing process
In addition, before the solder resistance film coating, the printed circuit board surface is treated by plasma, and a certain roughness and high activity surface can be obtained, so as to improve the adhesion of the solder resistance film.
How to judge the reliability of PCB, 14 important features tell you!
The chemical residue in the gold settling process can be left in the hole where the plug hole is not sufficient, causing problems such as weldability.
Flexible circuit board FPC surface plating knowledge
The multilayer soft PCB board made of polyimide film as the base material is about 1/3 lighter than the rigid epoxy glass cloth multilayer PCB board, but it loses the excellent flexibility of single-sided and double-sided soft PCB. Most of these products
Cause and countermeasure analysis of PCB factory epoxy floor paint bulges
There is no significant relationship between the generation of bulge and construction area, the same area some severe, some light, some intact.
Four layer board design
There is no denying that current industry trends and consumer demands are pushing designers and design teams to push the envelope and develop new electronic products to meet market challenges.
Why should PCB plug the hole?
The development of the electronics industry also promotes the development of PCB, which also puts forward higher requirements for the production process and surface mounting technology of printed board.
How to choose PCB surface treatment process?
The results show that the latest organic coating technology can maintain good performance in multiple lead-free welding processes.
