Why does miraclepwb make a high-reliability PCB board

Reliability = lifeline, which is vital to the success or failure of “electronic products” and “electronic enterprises”. It should not be underestimated or ignored!
Instead of choosing “low-end factories” to try your luck, it is better to join hands with “high-end manufacturers” to make big plans! Nine years of deep cultivation of “highly reliable multilayer PCB”, “miraclepwb” is only to make customers more worry-free, more secure, and more assured

Reliability engineering originated from the military industry and is a practical science that seamlessly integrates “engineering technology” and “management art”. The history of reliability is the history of lessons from unreliability

For products, reliability is the guarantee for the performance of the product. If the product is unreliable, the technical performance will not be used even if it is good. “Product reliability” is equivalent to product reliability! In other words, “high reliability” refers to a longer product life, and there are few or no failures during the product life cycle!

With the rapid development of science and technology, all walks of life have put forward higher and higher requirements for product reliability! Product reliability has become an inspection and evaluation index for product quality, and an important weight for companies to enhance their competitiveness and brand image!

1. The importance of high reliability to enhance the market competitiveness of electronic products
In 1992, when my country launched the “Austellite” due to a small part failure, the launch failed, which caused huge economic losses and political influence! Japanese automobiles, household appliances and other products occupy the international market, mainly because of high product reliability. The overhaul period of American Kang Mingxian diesel engines is 12,000 hours, while domestic diesel engines frequently fail within 1,000 hours……

For products, reliability is closely related to “maintenance costs, operating efficiency, property safety, casualties, economic benefits, and national security”. High reliability is an important guarantee for enhancing the market competitiveness of electronic products!

1. The importance of PCB high reliability
1) Only highly reliable PCBs can meet the market development needs of customers
A major feature of the development of modern science and technology is the highly complex structure of the equipment. Its notable sign is the variety of component requirements and the complexity of data. PCB is the core carrier of electronic product link components. The more layers, the more components, and the technology. The higher the requirements, the greater the impact on reliability, and the higher the requirements for PCB reliability. Only highly reliable PCBs can meet the development needs of our customers.


2) Highly reliable PCB can help customers improve their market competitiveness
Before World War II, Japan’s electronic products had a large number of returns due to poor reliability, and they were almost forced to withdraw from the international market. After World War II, Japan summed up its lessons and continuously improved the reliability level of electronic products, and finally it was able to greatly enhance its market competitiveness and seize a huge international market share. With the dual impact of the financial crisis and the new crown epidemic, the current international market competition is particularly fierce. For “miraclepwb”, only by effectively improving the reliability of PCB can we help customers improve brand reputation and continue to enhance market competitiveness!

3) Highly reliable PCB can help customers obtain higher economic benefits
In 1961, at least 25% of the U.S. Department of Defense’s budget was for maintenance. For the antenna products sold in the European or North American markets, since the tower operation requires the hiring of qualified professionals, the maintenance cost is slightly different from the single antenna price. In order to improve the reliability of a certain product, Westinghouse of the United States once conducted a comprehensive review and found that improving the reliability level can greatly reduce the maintenance costs of electronic equipment. On the surface, the high-reliability pre-production and control costs will be higher. However, the failure rate in the later stage is less, and maintenance costs and downtime losses will be lower. In order to help customers maximize their economic benefits, “miraclepwb” is more obsessed with making PCBs right, good and highly reliable once! !

2. PCB failure and its consequences analysis
The failure of PCB life cycle is highly related to reliability, and the consequences of failure caused by low PCB reliability are also very shocking.

As the carrier of electronic components and the hub of circuit signal transmission, PCB has become one of the most important and critical core components in electronic products. Its quality and reliability directly determine the quality and reliability of the entire electronic machine.

With the ever-increasing miniaturization, lighter weight, multi-functionalization of electronic products, and the continuous promotion of environmental protection requirements such as lead-free and halogen-free, the PCB industry is moving towards “fine lines, small holes, multiple layers, thin boards, high TG, high frequency , High-speed, high-density, and environmental protection, which has led to increasingly complex internal PCB structure, increased internal temperature rise, and deterioration of heat dissipation conditions, which greatly affected reliability.

Secondly, there are huge differences in the use environment of electronic products, from tropical to frigid zone, from land to deep sea, from high altitude to space, from laboratory to field… In addition to the effects of temperature and humidity, sunlight, dust, sea water Various environmental conditions, such as salt spray, impact, vibration, cosmic particles, and various radiation, will have varying degrees of impact on PCBs, and even lead to product failure. For example, in the coastal high-salt and high-humidity environment, a thin water film will form on the surface of the object, and when the relative humidity is 65%-80% in the air, the thickness of the water film on the object is 0.001~0.1μm, When the PCB is working with electricity, the water film and the hole copper together form an electrolytic cell, and an electrochemical reaction occurs, and finally black corrosives are generated, which poses a fatal risk to the reliability of the PCB.


There are many and different reasons for PCB failure, such as the corrosion failure of PTH hole copper, the open circuit failure caused by the bottom crack of the HDI blind hole, the layered plate failure, the ENIG hole ring crack failure, the open short circuit failure, etc. Different failure types will eventually affect maintenance costs, operating efficiency, economic benefits, brand image, and may even endanger property safety, casualties, and national security!

2. High reliability comes from “miraclepwb”‘s high quality standards and high production requirements
“High reliability” is a clear banner for an enterprise to stand on the market, empower customers, and fulfill social responsibilities. Since its establishment, “miraclepwb” has doubled its emphasis on reliability, and “high reliability” with “high investment, high standards, and high requirements”. After nine years of hard work and hard work, it has developed to the present day, “miraclepwb” “From oneself to others, we spare no effort to call on the industry to “emphasize reliability”. The reason is that “high reliability” is not only related to the long-term and stable development of the company itself, but also directly affects the brand reputation of downstream customers, and even the industry and the country’s international Market image in competition.
