The quality of raw materials is not up to standard

The quality of raw materials is the basic quality of circuit boards. The material itself is not up to standard. The circuit boards made will appear foaming, stratification, board warping and uneven thickness.

Production equipment is not up to standard

With the progress of science and technology, the replacement of PCB production equipment is faster and faster, and the price is more and more expensive. Equipment is to ensure the quality of hardware, increase investment in equipment, so that equipment to achieve high efficiency, stability is the fundamental way to improve the quality of circuit boards. As a result, some small PCB factories are unable to purchase expensive equipment, which ultimately leads to the poor quality of FPC products.

Production technology is not up to standard

Each process of PCB production must be carried out in accordance with strict production process, and each process must be equipped with corresponding inspection equipment. These process parameters and equipment can guarantee the stability of PCB quality. Because the production technology is not up to the standard, many PCB factories only have low prices, resulting in the quality of the production line board is not up to standard.

The first point is the circuit design

The PCB with good quality must have reasonable circuit design. Whether double-layer or multi-layer board, it must have accurate line control and reasonable trace trend, in order to avoid the slow response due to redundant lines, that is, line width, line thickness, line spacing meet the requirements, so as to avoid line heating, circuit breakage, and short circuit.

The second point is the appearance

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

The third point is the heat resistance of the product

This point should be observed personally, PCB circuit boards are assembled in their own products. If they can withstand the instantaneous high temperature produced by welding and the copper foil is not easy to fall off under high temperature, it shows that the PCB circuit boards have good heat resistance and good quality.

The fourth point is the expansion coefficient.
PCB circuit boards can produce drastic expansion or contraction in hot and cold environment. If the expansion coefficient is small and the thermal and cold environment has little influence on PCB circuit boards, the quality of PCB circuit boards is good and the components on PCB circuit boards will not be damaged.

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

Rocket PCB supply chain meticulously practices all-around quality management and actively introduces and implements multi-domain system management. We have successively obtained ISO9001, ISO14001, IATF16949, OHSAS18001, ISO/IEC27001, ISO13485 and AS9100 certifications.

PCB industry manufacturing level is uneven, compared with other low-end manufacturers, we have unparalleled advantages. Low-end manufacturing factories are facing various quality defects due to outdated equipment, confused site management, improper operation, poor quality control, insufficient skills of engineers and inadequate process control.
