What are PCB high frequency plates? How to choose?
PCB board selection must meet the design requirements, mass production, cost balance. In short, the design requirements include both electrical and structural reliability.
How to wire PCB design
No matter what work you are engaged in in the circuit board industry, if the circuit principle of electronic products is clear, you can improve the efficiency of functional testing and production efficiency of products. A trick takes you to understand the
Selection of PCB surface treatment technology
The choice of surface treatment process mainly depends on the type of final assembly components; The surface treatment process will affect the production, assembly and final use of PCB board.
Current situation of pcb industry
communication backplane, automotive board and other fields is relatively slow, while the HDI board, packaging board and soft board applied in high-end mobile phones, laptops and other "thin and short" electronic products will maintain rapid grow...
How to improve the reliability of PCB equipment
scheme selection, circuit design, circuit board design, structure design, component selection, production process, etc
PCB surface treatment method
There are many PCB surface treatment processes, the common ones are hot air leveling, organic coating, electroless nickel plating, gold dipping, silver dipping and tin dipping.
PCB equipment adjustment and interaction with corrosion solutions
At present, no matter what kind of etching fluid is used, high pressure spray must be used, and in order to obtain a cleaner line side and high quality etching effect, the nozzle structure and spray mode must be strictly selected.
Why did these PCB companies fail?
Needless to say, the PCB industry is facing increasing challenges and competition. But in trouble, lying flat can not save themselves, only fight, can be reversed.
Etching process of PCB outer circuit
This type of graphic plating is characterized by the presence of a copper coating only under the lead tin resist layer. Alternatively, the entire plate is coated with copper, with only tin or lead-tin resist outside the film
How to improve the PCB short-circuit problem
PCB circuit opening and short circuit are problems encountered by PCB manufacturers almost every day, so pcb manufacturers should pay attention to production and avoid short circuit problems
PCB Introduction to printed circuit boards
In this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.
