The quality evaluation of PCBA solder joint reliability is a core link in the field of electronic manufacturing. The need to conduct liability and quality evaluation was first put forward in light of the fact electronic products are expected to become high-density, multi-functional and highly reliable. As components become smaller and some packaged components with hidden solder joints become prevalent, traditional visual inspection can no longer meet the quality requirements. It is necessary to comprehensively inspect through means such as X-ray and slice analysis, and comprehensively evaluate key quality indicators such as solder joint porosity, wettability and shear strength. In the process of comprehensive evaluation, the quality of solder joints is evaluated through reliability tests and accelerated aging to meet the strict standards for product reliability in industries such as automotive electronics, aerospace and medical equipment, which further promotes the standardization and refinement of the solder joint quality evaluation system.

| Project Background

As electronic products become increasingly high-density and multi-functional, the soldering quality of PCBA has become a core factor in ensuring product reliability.

More and more industry standards have put forward strict requirements for the appearance and porosity of PCBA solder joints. In fields such as automotive electronics and aerospace, relevant certifications are required to ensure that the soldering quality meets the requirements before large-scale production. Therefore, inspection of PCBA soldering quality is crucial for the process production. In addition, soldering defects may lead to high rework costs and legal risks. Soldering quality evaluation test has become a key means to optimize parameters, improve efficiency and control quality.
