Multilayer printed circuit board, fast prototype PCB fabrication supplier

Multilayer PCB is one of the most distinguished products among those collections in Rocket PCB Solution Ltd.
It is designed by using superior and well-selected FR4. It comes with various structures. The design of it caters to varied needs of customers at home and abroad. Impedance control, dense circuit is adopted to produce high-quality Multilayer PCB. With such parameters as up to 64 layers, high reliable characterize Multilayer PCB.

Rocket PCB has been producing multilayer PCBs for over 20 years. Over the years, we have seen all types of multilayer constructions from various industries, answered all types of multilayer questions, and solved all types of problems with multilayer PCBs.

Reasons for the failure of PCB product quality

The quality of raw materials isn't as much as standard

The quality of raw materials would be the fundamental quality of circuit boards. The material itself isn't as much as standard. The circuit boards created will occur foaming, stratification, warping, and uneven thickness.

Production equipment is just not as much as standard

Together with the progress of science and technologies, the replacement of PCB production gear is quicker and quicker, as well as the cost is more and more expensive. Equipment is to assure the quality of hardware, improve funding in equipment, to ensure that equipment to attain higher efficiency, stability could be the basic method to strengthen the quality of circuit boards. Because of this, some small PCB factories aren't able to get high-priced equipment, which in the end results in the poor quality of Printed circuit board products.

Production technologies aren't as much as standard

Every approach of
PCB manufacturing should be carried out depending on stringent production procedures, and every procedure has to be equipped with related inspection equipment. These procedure parameters and equipment can assure the stability of PCB quality. Since the production technologies aren't as much as the standard, several PCB factories have only low prices, resulting in the quality of the manufacturing line board isn't as much as standard.

How to judge whether the quality of a PCB board is good

The first point will be the circuit design

The PCB with top quality must have a reasonable circuit layout. Whether double-layer or multiplayer board, it should have correct line control and reasonable trace pattern, in order to prevent the slow response on account of redundant lines, which is, line width, line thickness, line space meet the requirements, in order to prevent line heating, circuit breakage, and short circuit.

The 2nd point is the appearance

The PCB circuit board with top quality not only has a neat and smooth surface, and also basically does not appear the occurrence of bending or irregular. The copper surface is not easy to oxidize, and there will be no cracks or scars, print ink falling off.

The 3rd point is the heat resistance

This aspect needs to be observed personally, PCB circuit boards are assembled in their own products. If they can endure the instantaneous high temperature produced by welding as well as the copper foil is difficult to fall off under high temperature, it shows that the PCB circuit boards have excellent heat resistance and high-quality.

The 4th point is the expansion coefficient

PCB circuit boards can create drastic expansion or contraction in cold and hot environments. In case the expansion coefficient is small the thermal and cold environment has small effect on PCB circuit boards, the quality of PCB circuit boards is nice and the components on PCB circuit boards will not be damaged.

Advantages of PCB Multilayer Board

Compared with a double-layer board, the multilayer circuit board has greatly improved electromagnetic compatibility.

For example, in a four-layer board, the middle layer is used as a power layer and a ground layer, and the benefits of doing so are as follows,

(1) The inductance of the power wire and ground wire is greatly reduced, thus reducing the noise voltage

(2) The power supply layer and ground layer form a large distributed capacitor, which provides a good high-frequency decoupling effect for the power supply, thus reducing the noise on the power cord.

(3) Independent power and ground layer can minimize the area of all signal loops

PCB multilayer board is the trend of the circuit board industry, the circuit board industry is developing toward the smaller size, the smaller the hole, the thinner the thickness, the larger the number of layers, the smaller the line width and spacing and so on.

Many high-precision high-tech electronic products are required multilayer PCB board to achieve functions, the ordinary double-sided board simply cannot replace
