With the increasing complexity of electronic equipment and the need for more and more parts,PCB board lines and parts are increasingly dense. A board with no parts on it is called a "bare board" and is often called a "printed circuit board&...
PCB as the core substrate of electronic products, its quality and reliability directly affect the quality and reliability of electronic products, so high reliability PCB has become the basic requirements of many electronic products.
he price of PCB is something that many buyers are always confused about, and many people will also question how these prices are calculated when placing an online order. Let's talk about the components of PCB price together.
Radio frequency, high speed digital circuit: forbid acute Angle, try to avoid right Angle. Acute Angle is worst, right Angle is second, obtuse Angle is second, rounded Angle is second, straight line is best.
Wiring is one of the most basic job skills of PCB design engineer. The quality of wiring will directly affect the performance of the whole system. Wiring is very important in high speed PCB design.
For PCB engineers, the most important thing is to ensure that the advantages of differential routing can be fully utilized in the actual routing
Emc and associated EMI have historically required the eyes of system design engineers, but today board designs and component packages are shrinking and Oems are demanding faster systems.
Circuit is used as a tool for conduction between originals. In the design, large copper surface will be designed as the grounding and power layer. The lines and drawings are made at the same time.
hese wires, called wires or wiring, are used to provide circuit connections between the components on the board. Usually the color of PCB board is brown or green, which is the color of solder resistance paint.
The PCB dielectric loss factor increases, the loss becomes larger and larger, the transmission line length is larger, the loss is larger, the copper foil roughness is larger, the loss is larger.
PCB RF circuit RF interface, small expected signal, large interference signal, interference of adjacent channels four basic characteristics.
The key of RF circuit PCB design is how to reduce circuit radiation and improve anti-interference ability, but in the actual layout and routing of some problems are in conflict with each other.
