Flex Plus Soldering Control: Ensuring Quality FPCBs. Learn how it mitigates tin whisker risks, emphasizes collaboration and testing.

Introduction: The Importance of Quality Control in the Electronics Industry

The electronics industry has revolutionized the world with innovative and sophisticated products that have transformed the way we live and work. However, the manufacturing process of these products still presents challenges, one of which is the growth of tin whiskers on soldered components.


The Tin Whisker Issue: Lessons Learned from one Shenzhen FPC manufacturer and TDK Corporation

In 2017, there were reports of Tin Whisker issues between a Chinese FPCB supplier and a Japanese customer, TDK Corporation. The issue affected certain FPCB products supplied by a Shenzhen factory. The FPCs in question were manufactured using a tin-plated copper foil with insufficient surface roughness, which contributed to the growth of tin whiskers. This ultimately led to the failure of certain electronic components that were assembled with these FPCBs.

The incident highlights the importance of quality control in the electronics supply chain, especially when it comes to FPCBs. This is where Flex Plus soldering control comes into play, providing high-quality FPCBs while mitigating risks associated with tin whiskers.image.png

Flex Plus Soldering Control: A Comprehensive Quality Control Process for FPCBs

Flex Plus soldering control is a comprehensive quality control process that encompasses all stages of the manufacturing process, from the initial design stage to the final product assembly. The process involves the use of advanced technologies and techniques to monitor and control the soldering process, ensuring the reliability and performance of electronic products.

Key Components of Flex Plus Soldering Control: High-Quality Solder Alloys and Controlled Heating/Cooling Processes

One of the key components of Flex Plus soldering control is the use of high-quality solder alloys. These alloys are specially formulated to reduce the growth of tin whiskers, ensuring the longevity and reliability of electronic components. The use of controlled heating and cooling processes during soldering also helps to prevent mechanical stress on the components, reducing the likelihood of tin whisker growth.

Collaboration and Quality Testing: Ensuring High-Quality FPCBs throughout the Supply Chain

Flex Plus soldering control also places a strong emphasis on collaboration between suppliers and customers. By working together to identify and address potential issues in a timely manner, it is possible to ensure the quality and reliability of electronic products throughout the supply chain.

Moreover, rigorous quality testing procedures are implemented at every stage of the manufacturing process. These procedures include:

  • visual inspections,

 

  • electrical testing,

 

  • X-ray imaging 

to identify potential issues before they cause failure. This ensures that every FPCB that leaves the factory meets the required performance standards.


Conclusion: Flex Plus Soldering Control Mitigates Risks and Ensures High-Quality FPCBs in the Electronics Industry.

In conclusion, the incident between Shenzhen FPC supplier and TDK Corporation underscores the importance of quality control in the electronics supply chain, especially when it comes to FPCBs. Flex Plus soldering control provides a comprehensive solution for mitigating risks associated with tin whiskers, ensuring the high quality and reliability of FPCBs. With a strong emphasis on collaboration and rigorous testing procedures, suppliers and customers can work together to identify and address potential issues, ensuring the longevity and reliability of electronic products throughout the supply chain.
