Before understanding the PCB design copper platinum thickness, line width and current relationship, let's understand the conversion between the PCB copper thickness in ounces, inches and millimeters: "In many data tables, PCB copper thickness is ofte...
Therefore, on SMT printed boards, through holes are used only to connect the wires on both sides of the board, the number of holes is much smaller, and the diameter of the holes is much smaller. In this way, the assembly density of the circuit board can b
Flexible Printed Circuit (PCB) can be designed with the general design of PCB software. Also use Gerber format for FPC manufacturers. Because the manufacturing process is different from ordinary PCBS, each manufacturer will have their own limits on minimu

PCB circuit board manufacturers to PCB circuit board related design parameters detailed.
Now PCB design time is shorter and shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large size components make designers
How to improve SMT SMT processing efficiency: first, advance work preparation, second, ensure the SMT SMT machine running time balance, third, equipment operating parameters
Wiring is generally divided into three levels: one is the layout, which is the most basic requirements of PCB design, the second is to meet the electrical performance, which is the standard to measure whether the circuit board is qualified. Three is beaut
Polygon filling deviation usually occurs when polygon plating copper on multi-grid circuit boards. While it does not have a standard based on a single grid, it can provide service beyond the required life of the boards.
The first step to enter the PCB circuit board system is to set the PCB preset background, including setting the grid volume and type, cursor type, version layer reference, wiring reference, etc.
PCB design is based on the circuit schematic diagram to achieve the function required by the circuit designer. Excellent design can save production cost, achieve good circuit performance and heat dissipation performance.
From the current situation, only our country has recovered the supply of products in a short time, accelerating the trend of domestic replacement of PCB industry.
