Easy to manage circuit board components For a large led circuit board, it has a lot of parts package, there are thousands of networks, very messy, the use of the class can be very convenient to manage the circuit board.
The frequency of the digital circuit is high, the sensitivity of the analog circuit is strong, for the signal line, the high-frequency signal line is as far away from the sensitive analog circuit device as possible, for the ground line, the whole PCB has
Maintenance of spare printed circuit board. For the spare printed circuit board that has been purchased, it should be installed on the numerical control device regularly and run for a period of time to prevent damage;
In principle, right-angle wiring will cause the line width of the transmission line to change, resulting in impedance discontinuity. In fact, not only right Angle wiring, ton Angle, acute Angle wiring may cause impedance changes.
In circuit board design, we are usually very concerned about the quality of the signal, but sometimes we usually limit the research on the signal line, and the power and ground as the ambition of the situation to deal with, although this can make the ques
What should we pay attention to in the transmission line design of RF broadband circuit PCB? How to set the ground hole of the transmission line appropriately? Should we design the impedance matching by ourselves or cooperate with the PCB manufacturer?
The processing level should be defined clearlyWhen there is no clear place in the document, be sure to find a professional engineer to check, so as to reduce the chance of plate making errors
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
