Impact of Quad Flat No Lead package (QFN) on automated X-ray inspection (AXI)

QFN is increasingly being used on wireless cards, handhelds etc. However, QFN unique solder joints pose great challenges for AXI. This paper discusses lack of industry specification for QFN inspection, how AXI methodology was improved to detect QFN solder joint defect, design for inspection and future work.
