Reliability engineering originated from military products and is a practical science that seamlessly integrates “engineering technology” and “management art”. The development history of reliability is the output of new technology products that have achieved generation after generation
For pcb electronic products, reliability is the guarantee for the performance of the product. If the electronic product is unreliable, the technical performance will not be played even if it is good. Important [automobiles, medical electronics] have an important respect for safety. “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 it is also an important weight for PCB manufacturing 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 PCB layers, the more components, The higher the process requirements, the greater the difficulty of product manufacturing, the greater the reliability impact, and the higher the requirements for PCB reliability. Only highly reliable PCBs can meet the development needs of our customers. Of course, these are required by most 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 “fastpcba”, only by effectively improving the reliability of PCBs 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 has 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, “fastpcba” is more obsessed with making PCBs right, good and highly reliable once! !
2. Analysis of the failure and consequences of PCB electronic products
PCB life cycle failures are highly related to reliability, and the consequences of failures caused by low PCB reliability are also 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 level 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 the PCB, and even lead to product failure. For example, in a 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.
The reasons for PCB failure are various and different. For example, 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!
