An Overview of Non-Destructive Testing Methods for Integrated Circuit Packaging Inspection

Area of Science:

• Materials Science
• Electrical Engineering
• Reliability Engineering

Background:

• Integrated circuit (IC) packaging is crucial for device performance and longevity.
• Defects in IC packaging can lead to device failure and reduced reliability.
• Non-destructive testing (NDT) methods are essential for evaluating IC packaging integrity without causing damage.

Purpose of the Study:

• To provide a comprehensive review of state-of-the-art NDT methods for IC packaging.
• To identify common defect types and assess the capabilities of various NDT techniques for their detection.
• To analyze the principles, advantages, and limitations of current NDT methods and propose areas for enhancement.

Main Methods:

• Review of established NDT techniques including X-ray, Scanning Acoustic Microscopy (SAM), Infrared Thermography (IRT), Magnetic Current Imaging (MCI), and Surface Acoustic Waves (SAW).
• Analysis of the operational principles, strengths, and weaknesses of each method in the context of IC packaging.
• Comparative assessment of the reviewed NDT methods for defect detection efficacy.

Main Results:

• Detailed insights into the applicability and limitations of common NDT methods for detecting specific IC packaging defects.
• Identification of areas where current NDT techniques can be improved for enhanced defect characterization.
• Exploration of novel NDT technologies with potential for adoption in IC packaging evaluation.

Conclusions:
