Multilayer PCB Printed Circuit Boards Fabrication Process Advantages

Multilayer PCB Printed Circuit Boards Fabrication Process Advantages

Printed circuit boards advantage:

1. Wiring density, small size, light weight, which will help the miniaturization of electronic equipment.

2. As the graphics with repeatability and consistency, reducing wiring and assembly errors, saving the equipment maintenance, commissioning and inspection time.

3. Help mechanization, automated production, improve labor productivity and reduce the cost of electronic equipment.

4. Design can be standardized, conducive to exchange.

5. In particular, FPC flexible board resistance to bending, precision, and better should be to high-precision instruments.

Multilayer Fr4 PCB advantage:

Multilayer fr4 pcb is made of glass fabricated plastic with copper tracks that act as wire to which the components are attached. In order for components to be properly placed into the board, the production requires holes to be drilled on the board. PCB is soldered to create a stronger hold for the components. Printed circuit board is one of the new wonders in the modern production of electronics parts.

Although the PCB is one of the most convenient electronic boards to use today, it still has advantages and disadvantages on the application. Below is the list of both the advantages and disadvantages of using printed circuit boards.

The multilayer PCB circuit board has many featured advantages such as high mounting density, small size and light weight. Due to the high mounting density, the wire connecting between these electrical components will be greatly reduced thereby the reliability of the PCB board will be totally enhanced. Furthermore, the number of the wiring layers can be increased thereby people could find that the design flexibility of the multilayer PCB circuit board is very high. Thirdly, the multilayer PCB circuit board could be able to constitute the certain impedance circuit and form the high-speed transmission circuit. Fourthly, the multilayer PCB board could also set the circuit, magnetic shielding layer and metal core cooling layer to meet the demand of shielding, thermal radiating and others.

In addition to all above advantages, the multilayer PCB circuit board also own many disadvantages such as high production cost and long period designation time. After the processes of production, this product also requires many high reliability means of detection.

The technician from famous China pcb factory oneseine PCB said that the Multi-layer printed circuit is the product of electronic technology which aims to reach to the level of high-speed, multi-function, high-capacity and small size. With the continuous development of electronic technology especially the extensive application of the large-scale and ultra large scale integrated circuits, the multi-layer printed circuit rapidly develop to the technical direction of high designation density, high precision, high number of layers.

Micro-via advantages in multilayer pcbs：

Shorter trace lengths

Fewer signal layers – due to shorter trace lengths

Enhanced RF-capability – due to same

Improved EMC-characteristics – due to same

More room for components – often two sided assembly can be avoided

Much more room for components with R7011 build

Smaller pcb for same functions possible

Micro via technology have better reliability than through holes

Integration of screen resistors resistors on layers 2 and n-1 is feasible

Reduction of  drilled through-holes

Environmentally friendly
