PCB circuit board design and component wiring rules

The basic process of PCB circuit board design in SMT chip processing requires special attention. One of the main purposes of circuit schematic design is to provide a network table for PCB circuit board design and to prepare the basis for PCB board design. The design process of a multi-layer PCB c... Read More

What is the difference between the production process of multi-layer board and double-layer board?

In general: compared with the production process of multi-layer board and double-layer board, there are 2 more processes, respectively: inner line and lamination. In detail: in the production process of double-layer plate, after the cutting is completed, drilling will be carried out, and then int... Read More

How to do the via and how to use the via on the PCB?

The via is one of the important components of multi-layer PCB, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB board. Simply put, every hole on the PCB can be called a via. The basic concept of the via: From the point of view of function, the via can be divided i... Read More

How to place both RF circuit and digital circuit on PCB board?

If the analog circuit (RF) and the digital circuit (microcontroller) work well individually, but once you put the two on the same circuit board and use the same power supply to work together, the entire system is likely to be unstable. This is mainly because the digital signal frequently swings b... Read More
