PCBA refers to a circuit board with various components soldered on the surface. People often pay attention to its long-term, high-frequency operation reliability, and occasionally need to understand its shelf life. Generally, the shelf life of PCBA boards is 2~10 years, which is mainly affected by the following factors:
1. Environment
A humid and dusty environment is obviously not conducive to the preservation of PCBA. These factors will speed up the oxidation and dirt of PCBA and shorten the shelf life of PCBA. Generally, it is recommended to store PCBA in a dry, dust-free space with a constant temperature of 25 ℃.
2. Reliability of components
The reliability of components on different PCBAs also determines the shelf life of PCBA to a large extent. Components with high-quality materials and processes have the ability to withstand harsh environments, with a wider range of capabilities and stronger oxidation resistance, so that PCBA stability is guaranteed.
3. The material and surface treatment process of the circuit board
The material of the circuit board itself is extremely unlikely to be affected by the environment, but its surface treatment process is greatly affected by air oxidation. Good surface treatment can extend the shelf life of PCBA.
4. PCBA board running load
PCBA running load is the most important factor in its shelf life. The operation of high frequency and high load will cause continuous and high impact on circuit board circuits and components, and will be more susceptible to oxidation when affected by heat, resulting in long-term operation, such as short circuit, open circuit, etc. Therefore, the operating parameters of the PCBA board should preferably be in the middle value range of the components and avoid near the peak value, which can effectively protect the PCBA and extend its shelf life.
The shelf life of PCBA boards is a comprehensive work, which needs to follow scientific design specifications, manufacturing process specifications, and operation specifications, so that the shelf life can be extended to the greatest extent.
Why Choosing Grande To Do Small Batch SMT Assembly?
1. Strength Guarantee
▪ SMT factory: With imported SMT machines and multiple optical inspection equipment, which is able to produce 4 million points per day. Each process is equipped with QC personnel who will keep an eye on product quality.
▪ DIP production line: Two wave soldering machines and more than 10 employees who have worked for over three years. That’ s to say, these workers are highly skilled and can weld various SMT & DIP components.
2. Quality Assurance With High Cost Performance
▪ High-end equipment can paste precision special-shaped parts, BGA, QFN, 0201 package. It can also be soldered prototype pcba via SMT machine and placing bulk materials by hand.
▪ Both samples, small and large batches can be produced. And there is no SMT Machine starting cost.
3. Rich Electronic Products SMT Soldering Experience With Stable Delivery
▪ Accumulated services to thousands of electronics companies, involving SMT soldering services for various types of automotive equipment and industrial control motherboards. Furthermore, PCBA products are often exported to Europe and the United States, and the quality is able to be affirmed by new and regular customers.
4. Strong Maintenance Ability & Reliable After-Sales Service
▪ The maintenance engineers have sophisticated experience so that those defective boards caused by all kinds of smt soldering can be repaired. Meanwhile, ensuring the connectivity rate of each circuit board also make sense.
▪Order problems feedback will get response, solution and solved as soon as possible.
