Printed Circuit Board (PCB for short) is an important part of electronic equipment, which realizes the function of the circuit by connecting electronic components and circuits together. The principle of printed circuit board mainly includes the following aspects: Basic structure A printed circuit board usually consists of a substrate, wires, holes, and pads. The substrate …
The biggest difference between flexible electronic printing and printed circuit board is that the current carrying capacity of wires is different. The heat dissipation capacity of flexible electronic printing is relatively poor, so the current carrying capacity it can bear is relatively small; The heat dissipation capacity of printed circuit board is relatively strong, and …

The common substrate materials of printed circuit boards include paper-based CCL, epoxy glass cloth based CCL, composite CCL, metal based CCL, flexible CCL, ceramic substrate, copper-clad polyimide glass fiber cloth laminate and BT resin for high-frequency circuits. 1. Paper Based CCL Paper based CCL is made of fiber paper + adhesive through drying → copper …

Printed circuit board (PCB) is an important electronic component and the support of electronic components. Because it is made by electronic printing, it is called “printed” circuit board. In the production of electronic products, there will certainly be a production process of printed circuit board. Printed circuit boards are used in electronic products in all …

Printed Circuit Board Faults 1. Poor Contact Poor contact between board and slot, broken cable, poor contact between wire plug and terminal, false soldering of components and so on all belong to this category. The solution to this kind of fault is to carefully check the suspected connector to see if there is obvious oxidation …

Because most of the modern printed circuit boards have no official schematic and more and more chip applications with programs, engineers will face challenges in various aspects. Through a lot of practice, there are still ways to avoid these challenges. I will share 6 maintenance methods of PCB. Tip 1: Appearance Inspection Looking, asking, smelling …
