PCB circuit board design should pay attention to the seven steps

The first step to enter the PCB circuit board system is to set the PCB preset background, including setting the grid volume and type, cursor type, version layer reference, wiring reference, etc.

Why should PCB circuit board sink gold and gold plating, what is sink gold and gold plating

The most fundamental difference between gold plate and gold plate is that gold is hard gold (wear-resistant), gold is soft gold (not wear-resistant).

PCBA circuit board three anti paint use precautions

Precautions for applying three anti - paint:1, can not let the PCB circuit board surface dripping, fluid paint, semi-humid phenomenon, 2, should ensure that the three anti paint uniform, bright, smooth, 3, can not let the surface of the paint layer of pin

Notice and operation skills of circuit board design

For you to introduce the circuit board design precautions and operation skills :1, the processing level definition to be clear, 2, the distance from the copper foil frame can not be too close, 3, can not use the filler block picture welding pad, 4, electr

Damage analysis of PCB circuit board deformation and improvement measure

Basically, V-Cut is the culprit of damaging the structure of the board, because V-Cut is in the original a large sheet of the board to cut out grooves, so the V-Cut place is prone to deformation.

Printed circuit board assembly technology

The performance of reflow heating process: (1) good wettability, (2) reduce the formation of solder ball, (3) less solder spatter when reflow temperature rises sharply, the solder paste will appear almost boiling phenomenon, causing solder particle spatte

What are the characteristics of the flexible circuit board patch

The characteristics of flexible circuit board patch: 1, flexible circuit board patch after all lines configuration, less than other circuit board assembly, 2, flexible circuit board itself small size is more convenient to carry, 3, light weight, flexible

Explain the importance of electroplating for printed circuit boards

The interconnection of various plates in electronic facilities often requires the use of PCB plug sockets with spring contacts and a matching preset printed circuit board with connected contacts.

How to design anti-jamming PCB circuit board?

In the high frequency circuit, the noise of the power supply has an obvious influence on the high frequency signal. Therefore, the first requirement is that the power supply be low noise. Clean land is just as important here as clean power.

Circuit board working principle and composition principle of explanation

The working principle of the circuit board is to use the board based insulation material to isolate the outer copper foil conductive layer, so that the current flows along the preset route in various components.

How should industrial control circuit board be repaired

enterprises have developed and designed epoxy resins with high speed and high frequency plug holes, expecting to show epoxy resins with stronger transmission for customers and help customers improve the competitiveness of products

FPC (flexible circuit board) three types of introduction

Flexible PCBS (FPCS) are increasingly needed, and PCB manufacturers are accelerating the development of thinner, lighter and more dense FPCS.
