What is copper pour? Mesh copper pour or solid copper pour?

1. What is copper clad The so-called copper pouring is to use the idle space on the circuit board as the reference plane, and then fill it with solid copper. These copper areas are

Stamp hole, V-CUT, which one is better for PCB panel

Which is better for PCB Panel? First of all, we must understand why the jigsaw puzzle~ Panel is to meet production needs. For example, some customers' boards are too small, which d

What is PCB assembly process

Although many engineers are very familiar with the design and manufacturing process of printed circuit boards (PCB), there are still many engineers who are not clear about the asse

Parasitic Capacitance and Parasitic Inductance of Via

1. Via Vias are one of the important components of multilayer PCBs, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB manufacturing. Simply put, every hol

Why must the via hole of the PCB be plugged

Conductive hole Via hole is also known as conduction hole. In order to meet customer requirements, the circuit board via hole must be plugged. After a lot of practice, the traditio

PCB horizontal electroplating technology introduction

I. Overview With the rapid development of microelectronics technology, the manufacturing of circuit board manufacturing has developed rapidly in multi -layered, accumulated, functi

PCB Board Basic Knowledge

When making a robot, the PCB board is inevitable. The previous understanding of it will only be used at this level. Recently, I learned the production of PCB board and found that I

What is PCB vias, blind vias, buried vias, drilled vias

Via hole (VIA), the copper foil line between the conductive patterns in different layers of the circuit board is conducted or connected with this kind of hole, but it cannot be ins

What is PCB Impedance

In a circuit with resistors, inductors, and capacitors, the resistance to alternating current is called impedance. Impedance is often represented by Z, which is a complex number. T

What does the PCB board edge do

In the PCB production process, there is another important process, that is, the process edge, and the reservation of the process edge is of great significance for the subsequent SM

Ceramic circuit board introduction The ceramic circuit board is a kind of thermally conductive organic ceramic circuit board with a thermal conductivity of 9-20W/m.k prepared at a

PTH process in PCB manufacturing

Electroless copper plating, also known as plated through hole (PTH), is a self-catalyzed redox reaction. The PTH process is performed after drilling two or more layers. The functio
