FAQ
What is a wire bond inspection machine?
A wire bond inspection machine is an automated optical inspection (AOI) system used to verify wire bond quality, bond placement accuracy, loop geometry, and packaging integrity in semiconductor manufacturing.
Why is automated wire bond inspection important?
Automated wire bond inspection eliminates human inspection variability, increases defect detection rates, improves production yield, and ensures compliance with automotive and semiconductor quality standards.
What types of wire bond defects can the Wi300 detect?
The WI300 detects a comprehensive range of wire bond defects, including lifted bonds, missing wires, wire sag, loop height deviations, bridging and misaligned bond pads, all at a minimum detectable size of 5um × 5um.
Is the WI300 compatible with existing wafer map systems?
Yes. The WI300 outputs STIF-format wafer map files, which are compatible with most semiconductor MES and ERP platforms. Custom format integration is available on request.
Can it handle warped or non-planar wafers?
Yes. The built-in confocal displacement sensor detects wafer warpage and automatically compensates height deviations up to 2mm without requiring manual fixture changes.
What wafer sizes does the WI300 support?
The WI300 supports wafers from 4″ tiles up to 12″ full wafers, covering a wide range of semiconductor front-end production formats.
What industries use the WI300?
The WI300 is deployed in semiconductor front-end assembly, LED/optoelectronics, power semiconductors, automotive electronics, and medical device manufacturing — any application requiring 100% inline wire bond quality assurance.
How does the WI300 compare to manual or sampling-based inspection?
Unlike manual inspection or sampling, the WI300 delivers 100% automated in-line coverage at production speed, eliminating human error, reducing inspection labour, and providing traceable digital quality records for every wafer.
Is the WI300 suitable for automotive EV electronic assembly lines?
Absolutely. EV power modules require heavy wiring that carries intense current under continuous vibration. The WI300 provides the high-resolution tracking needed to enforce zero-escape quality standards for critical automotive sensors, ECUs, and inverters.
How does the WI300 integrate with Smart Factory AI systems?
The machine features full SECS/GEM communication protocols. It instantly packages inspection tracking data and STIF wafer maps, allowing centralized factory AI algorithms to monitor microscopic process variations over time and optimize active wafer die and wire bond inspection system runs automatically.
What is wafer mapping in semiconductor inspection?
Wafer mapping is the process of visually displaying inspection results across a wafer, allowing engineers to identify defect patterns, monitor process stability, and improve manufacturing yield.
