Successful Case of BGA132 NAND FLASH Storage Particle Carrier Board Packaging

1、 Project Background

With the rapid development of the digital economy, the demand for data storage has shown explosive growth. As the core component of various storage devices, the packaging technology of NAND FLASH storage granules directly affects the performance, reliability, and cost of the final product. In various fields such as industrial control, automotive electronics, and consumer electronics, customers have increasingly high requirements for storage products: they not only need stable read and write performance, but also must be able to adapt to harsh working environments while balancing volume and cost control.

Traditional storage packaging solutions often face challenges such as insufficient welding reliability, poor seismic performance, and high costs when facing industrial wide temperature environments, high vibration conditions, and long-term uninterrupted operation. To address these industry pain points, our company relies on our deep technical experience in the field of carrier packaging, and has successfully developed BGA132 storage granule packaging technology based on the characteristics and application requirements of NAND FLASH storage granules, providing customers with a comprehensive optimized storage packaging solution.

2、 Technical solutions and core highlights

This project adopts BGA (Ball Grid Array) packaging technology and has specially optimized the electrical characteristics and physical structure of NAND FLASH storage particles. The core highlights are as follows:

132 solder ball array design ensures electrical and welding stability

This packaging scheme adopts a precise array layout of 132 solder balls, which has undergone rigorous electrical simulation and physical testing to ensure the integrity and consistency of all IO serial port signal transmission, effectively reducing signal interference and transmission delay. At the same time, the uniformly distributed solder ball array greatly improves the reliability of SMT surface mount soldering, reduces the probability of welding defects such as virtual soldering and false soldering, and improves product yield and consistency.

Wide temperature reliability design to meet the requirements of industrial and automotive applications

In the design and production process, the product fully adopts industrial grade materials and processes, and has undergone rigorous temperature cycling testing, high temperature and high humidity testing, cold and hot shock testing, and other reliability verifications. It can work stably in a wide temperature environment of -40 ℃ to 85 ℃. This feature enables it to perfectly adapt to application scenarios with severe temperature changes and harsh environmental conditions, such as industrial control sites and vehicle electronic systems.

Comprehensive performance optimization to achieve multiple advantages

This packaging technology achieves comprehensive optimization of cost, volume, and seismic performance while ensuring performance and reliability. By adopting advanced carrier board design and manufacturing processes, the cost of raw materials and processing has been effectively reduced; The compact packaging structure significantly reduces the size of the product, providing more space for the miniaturization design of terminal devices; At the same time, BGA packaging itself has good mechanical properties, combined with our unique structural design, significantly improving the product's seismic resistance and effectively resisting vibration and impact during transportation and use.

Adapt to low load and long-term power on scenarios

In response to the long-term uninterrupted operation requirements of storage devices in industrial control, security monitoring and other fields, this packaged product has been specially optimized for low power consumption and high stability. It can maintain stable operation under low load conditions, with a long service life and extremely high reliability, meeting customers' needs for long-term stable operation of the product.
