PCB process classification

According to the number of PCB layers, it is divided into single-sided, double-sided, and multi-layer boards. The three board processes are not the same. There is no inner layer process for single-sided and double-sided panels, basically cutting-drilling-follow-up process. Multilayer boards will ... Read More

Increase knowledge! A detailed explanation of 16 common PCB soldering defects

There is no gold, no one is perfect”, so does PCB board. In PCB welding, due to various reasons, various defects often appear, such as virtual welding, overheating, bridging and so on. This article, We explain in detail the appearance characteristics, hazards and cause analysis of 16 common... Read More

What effect does the color of solder mask ink have on the board?

  From PCB World, Many people use the color of the PCB to distinguish the quality of the board. In fact, the color of the motherboard has nothing to do with the performance of the PCB. 　　PCB board, not that the higher the value, the easier it is to use. 　　 The color of the PCB surface is...

Characteristics and discrimination of resistance damage

It is often seen that many beginners are tossing on the resistance when repairing the circuit, and it is dismantled and welded. In fact, there are a lot of repairs. As long as you understand the damage characteristics of the resistance, you don’t have to spend a lot of time. Resistor is the... Read More

What is PCB layout

The PCB layout is a printed circuit board. The printed circuit board is also called a printed circuit board, which is a carrier that allows various electronic components to be connected regularly.   PCB layout is translated into printed circuit board layout in Chinese. The circuit board on t... Read More

These 10 simple and practical PCB heat dissipation methods

  From PCB World For electronic equipment, a certain amount of heat is generated during operation, so that the internal temperature of the equipment rises rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, and the device will fail due to overheating. The ... Read More

Common PCB debugging skills

From PCB World.   Whether it is a board made by someone else or a PCB board designed and made by yourself, the first thing to get it is to check the integrity of the board, such as tinning, cracks, short circuits, open circuits, and drilling. If the board is more effective Be rigorous, then you c... Read More

In PCB design, what safety gap issues will be encountered?

We will encounter various safety spacing issues in ordinary PCB design, such as the spacing between vias and pads, and the spacing between traces and traces, which are all things we should consider. We divide these spacings into two categories: Electrical safety clearance Non-electrical safety ... Read More

Do you really understand V-cut after doing PCB for so long? ​

PCB assembly, the V-shaped dividing line between the two veneers and the veneers and the process edge, into a “V” shape; After welding, it breaks off, so it is called V-CUT.   Purpose of V-cut The main purpose of designing V-cut is to facilitate the operator to divide the board afte... Read More

A well-qualified device package should meet the following conditions:

1. The designed pad should be able to meet the size requirements of the length, width and spacing of the target device pin. Special attention should be paid to: the dimensional error generated by the device pin itself should be taken into account in the design — especially the precise and d... Read More
