About PCB process flow
For designers, our main consideration is the minimum line width of wiring, spacing control and wiring uniformity. Because the spacing is too small will cause the clip film, film can not fade resulting in short circuit.

How to make PCB quickly
With the continuous improvement of electronic communication technology, more and more traditional circuit board manufacturing methods have been far from meet the rapid development of this era, want to really fast production of high precision, good perform
The harm of finger contact PCB is briefly introduced
Therefore, staff should develop the habit of wearing gloves, which can reduce the harm of direct contact with pcb board. The following is a brief introduction of a hand printing will lead to bad pcb board reasons, hazards, and how to avoid.
Understand crystal oscillator from PCB circuit board
Crystal oscillator is short for crystal oscillator. In fact, the common term crystal oscillator also includes crystal resonator, because the core is a quartz crystal.
Must PCB circuit board do impedance?
the tin plating of pcb circuit board is the most prone to problems in the production of the whole circuit board, is the key link affecting the impedance. The biggest defect of electroless tin layer is easy to change color (easy oxidation or delixing), poo
PCB board making technology
All the technical requirements mentioned above should be prepared before light painting. Such as mirroring, solder expansion, process line, process frame, line width adjustment, center hole, contour line and other issues should be in
PCB surface mounting technology
Therefore, even for the density is not high, the general number of circuit board, circuit board automatic detection is not only basic, but also economical. In complex circuit board inspection, two common methods are the needle bed test and the double prob
PCB design experience
Layout is an important part of design. The result of layout will directly affect the effect of wiring, so it can be considered that a reasonable layout is the first step of successful PCB design.
The growth history of PCB
In this case, the cost pressure of the downstream industry may be partially passed on to the printed circuit board industry, and the obstacles to higher prices of printed circuit boards are greater.
How to draw the perfect PCB board?
Priority shall be given to the layout of important unit circuits and core components. Routing signal line priority: analog small signal, high-speed signal, clock signal and synchronization signal and other key signals priority wiring.
Diversification of PCB
Therefore, the combination of soft and hard board, is the flexible circuit board and hard circuit board, after pressing and other processes, according to the relevant process requirements combined together, the formation of a circuit board with FPC charac
PCB detailed layout, wiring design overview
For some simple products, PCB design may simply connect all the devices and networks accordingly. For high-speed circuit, RF circuit, PCB design directly affects whether the function of the product is normal, whether the product can meet the market requir
