How is the circuit board of the PCB factory made? The small circuit material that can be seen on the surface is copper foil. Originally, the copper foil was covered on the entire PCB, but part of it was etched away during the manufacturing process, and the remaining part became a mesh-like small circuit. .   These lines are called wires or traces and are used to provide electrical connections...

The base material of the circuit board of the electro-acoustic PCB factory only has copper foil on both sides, and the middle is the insulating layer, so they do not need to be conductive between the Double sides or multi-layer circuits of the circuit board? How can the lines on both sides be connected together so that the current flows smoothly? Below, please see the electroacoustic PCB manufactu...

High precision circuit board refers to the use of fine line width/spacing, tiny holes, narrow ring width (or no ring width), and buried and blind holes to achieve high density. And high precision means that the result of "thin, small, narrow, thin" will inevitably bring high precision requirements, take the line width as an example: O. 20mm line width, according to the regulations to produce O. 16...

First of all, as a printed circuit board, PCB mainly provides interconnection between electronic components. There is no direct relationship between color and performance, and the difference in pigments does not affect the electrical properties.  The performance of the PCB board is determined by factors such as the material used (high Q value), wiring design, and several layers of t...

The rapid development of the mobile phone, electronics, and communication industries promoted the continuous growth and rapid growth of the PCB circuit board industry. People have more requirements for the number of layers, weight, precision, materials, colors, and reliability of components. However, due to fierce market price competition, the cost of PCB board materials is also on a rising t...

Vias in the circuit board are called vias, which are divided into through holes, blind holes and buried holes(HDI Circuit Board). They are mainly used to connect wires on different layers of the same network and are generally not used as soldering components; The pads in the circuit board are called pads, which are divided into pin pads and surface mount pads; pin pads have solder holes, which are...
