pcb Wiring Principles Share tips for PCB power wiring
It can be said that pcb routing is the most important and time-consuming process in the entire PCB design. Here we share some pcb routing principles.

New PCB Designer's Guide
Isolation - Ensure that each circuit of power is kept power and control separate. If you must connect them together in the PCB, make sure it is as close to the end of the power path as possible.
Notice of layout in PCB design
It is essential to use high dielectric strength materials that can resist higher voltages before breakdown.
Precision control skills and methods of PCB board milling
The milling technology of NC circuit board milling machine includes the selection of cutting direction, compensation method, positioning method, frame structure, the next cutter point, which is an important aspect to ensure the milling precision.
Use and development trend of PCB surface treatment
The choice of surface treatment process mainly depends on the type of final assembly components; The surface treatment process will affect PCB production, assembly and final use.
PCB surface treatment process characteristics
The purpose of the surface treatment is to ensure good solderability or electrical properties. Since copper tends to exist in the air as an oxide and is unlikely to remain as raw copper for long periods of time, other treatments of copper are required.
Power PCB design skills
When PCB size is too large, the printed line is long, the impedance increases, the anti-noise ability decreases, and the cost increases. Too small, the heat dissipation is not good, and the adjacent lines are susceptible to interference.
Gold, silver, copper in PCB board
PCB as the support body of electronic components, its surface needs to be welded components, it requires a part of the copper layer exposed for welding. Hence the need to brush solder resistance paint.
Three reasons tell you why PCB board copper dumping situation
When the copper wire on PCB board is soaked in etching liquid for a long time, it will cause some fine line backing zinc layer to be completely reacted off and separated from the substrate, that is, the copper wire falls off.
What is the use of gold, silver and other precious metals on PCB
Whether gold or silver, the purpose of the process itself is to prevent oxidation, protect the pad, so that it in the subsequent welding process to ensure yield.
Basic inspection of PCB board
The quality of PCB directly affects the quality of the whole electronic products, PCB testing is a timely detection of problems, but also a necessary means to prevent more defective products to reduce losses.
PCB auto routing
In order to obtain the best performance of electronic circuits, the layout of components and wires are very important, and wiring as the top priority of PCB design process, which will directly affect the performance of PCB board.
