What are the advantages of the high quality PCB circuit board

With the rapid development of mobile phone, electronic, telecommunications and other industries, continue to grow and rapid growth at the same time also prompted the PCB circuit board industry quantity, number of people, for the weight of components, precision, material, color, reliability and demand more and more.

But because the market price competition, PCB plate material cost is rising, more and more manufacturers in order to enhance the core competitiveness, at a low price to monopolize the market. However, these ultra low cost is behind, reduce the material cost and production cost to obtain, but the devices are usually easy to crack (crack), easy to scratch, (or, the scratch) precision, comprehensive performance factors did not seriously affect the standards, products for use in the solder ability and reliability and so on.

In the face of the market all kinds of PCB circuit board, circuit board or can distinguish PCB from two aspects; the first method is to judge from the appearance, the other is from the PCB board itself to determine the quality specification requirements.

The judgment method of PCB circuit board is good or bad:

The first to distinguish from the appearance of the quality of circuit board

In general, the PCB circuit board can look through three aspects to analyze and judge;

◎standard size and thickness.

The thickness of the standard circuit board of the circuit board is different in size, customers can check the measurement according to the thickness and specifications of their products.

◎light and color.

The external circuit board has ink coverage, the circuit board can play the role of insulation board, if the color is not bright, less ink, insulation board itself is not good.

◎the appearance of weld seam.

The circuit board due to multiple parts, if welding is not good, the circuit board parts easy to fall off, seriously affect the quality of welding circuit board, good appearance, careful identification, strong interface is a very important point.

Second: high quality PCB circuit board needs to meet the following requirements

◎requirement of component installed after the telephone is used, the electrical connections shall meet the requirements of;

◎line width, line thickness, line spacing to meet the requirements, so as to avoid the heat of the circuit breaker, and short circuit;

◎by the high temperature copper is not easy to fall off;

◎the copper surface is not easy to oxidation, the installation speed, after oxidation soon broke;

◎no additional electromagnetic radiation;

◎no deformation of shape, so as to avoid the deformation of the casing after installation, screw hole dislocation. Now is mechanical.

◎installation, circuit board hole and line design and deformation of the error should be within the allowable range;

◎high temperature, high humidity and high special environment should also be considered within the scope of;

◎mechanical properties of the surface to meet the installation requirements;

The above is the PCB circuit board judge method, when the purchase of PCB circuit board, must keep their eyes open.
