Copper coating as an important part of PCB design, whether it is domestic PCB design software, or some Protel abroad, then how to apply copper?
Defects in the PCB board design process will bring huge hidden dangers to the finished product.
24 tips to reduce noise and electromagnetic interference in PCB design,
Signal interference is the most important factor to consider in PCB layout design. Here are some basic ideas for reference.
The significance of copper coating is to reduce the ground impedance and improve the anti-interference ability. Reduce voltage drop, improve power efficiency.
The above is for everyone to share the PCB board interconnect high frequency PCB design skills, if you are familiar with these methods, you can understand the use of back copper-covered coplanar microstrip design than strip line design is more economical
A smart bracelet is usually composed of a radio frequency circuit unit, a clock circuit unit, a memory circuit unit, a sensor circuit unit and a main control MCU unit, etc., and the circuit PCB is usually concentrated in a small range, single-sided or dou
PCB circuit board is the basic electronic components of all electronic circuit design, and the design of PCB circuit board is also a must understand for makers. The role of PCB is not only to combine scattered components, but also to ensure the regularity
in the board frame, to determine the positive and negative, it is best to place all devices on the same side, which is marked with three XXX, as shown in the figure below.
It is a welding method that the welding end face of the components and the PCB welding pad are coated with paste solder and assembled together, heated until the solder is melted, and then the welding area is cooled.
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 mobile power supply plays a role of small body and large function, which needs to be regulated by a special circuit through voltage conversion to achieve charging support for special products.
