In PCB design, there are layout requirements for some special devices

PCB device layout is not an arbitrary thing, it has certain rules that need to be followed by everyone. In addition to general requirements, some special devices also have different layout requirements.   Layout requirements for crimping devices 1) There should be no components higher than 3...

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
