What is a Semiconductor visual inspection equipment?

A semiconductor appearance inspection system is a high-precision device used to inspect the surface of semiconductor chips and wafers to detect minute defects and foreign particles. Since even minor abnormalities can significantly impact product performance and yield in semiconductor manufacturing, high-speed and highly accurate inspection is essential. This system utilizes optical microscopes, lasers, and image processing technologies to automatically detect scratches, contaminants, and pattern defects. Additionally, AI and deep learning-powered inspection systems are increasingly being adopted for more precise classification and analysis.

Common applications include silicon wafer surface inspection, post-packaging chip appearance inspection, and quality inspection of solder joints on PCBs (Printed Circuit Boards). This system is crucial for improving quality and production efficiency in the semiconductor industry.

Application of Semiconductor visual inspection equipment

✅Wafer Inspection System
A system that scans the surface of silicon wafers using high-resolution cameras and lasers to detect microscopic scratches, foreign particles, and pattern defects. It can identify defects at the nanometer level, ensuring quality control in the early stages of semiconductor manufacturing.
✅Package Inspection System
A system used to check for surface scratches, chipping, and foreign material contamination after semiconductor chips are sealed in packages. It supports various package types, such as BGA (Ball Grid Array) and QFP (Quad Flat Package).
✅Wire Bond Inspection System
A system that inspects wire bonding quality after the bonding process, detecting misalignment, wire breakage, and ball bond defects. Some models integrate X-ray inspection to check internal bonding conditions.
✅PCB Inspection System
A system used to inspect solder joints and micro wiring defects on printed circuit boards (PCBs) where semiconductor chips are mounted. It helps detect solder bridges, disconnections, and foreign material contamination, ensuring high-quality electronic products.
