Product Technical Features
1. Pick-and-Place Machine Data Import Function
The data from the pick-and-place machine can be used to automatically generate programming data, significantly boosting programming speed.
2. Asynchronous Manual Verification Process
Operators’ assessments are conducted simultaneously with machine testing, allowing them to review the test results of the first 20 boards. Combined with the automatic front-to-back detection feature, this significantly boosts inspection speed.
3. Select any MARK point as needed
In addition to using traditional circular, rectangular, cross-shaped, and triangular markers as MARK points, you can also employ any distinctive-shaped marker as a MARK point. Up to three backup MARK points can be selected to ensure precise board positioning.
4. Robust detection capability for photoresist materials
Powerful automatic adjustment features allow even very dark photoresist materials to be handled effortlessly, with no need to manually adjust the lighting.
5. Discrete Component Color Ring Test
Industry-leading, reliable color-ring component testing technology that automatically eliminates lighting interference to accurately extract color-ring color information for testing.
6. Arbitrary-angle measurement method
All components, solder joints, solder, and bridging tests can be performed at any angle.
7. Automatic Segmentation of IC Pins and Discrete Component Leads
Automatically segments IC pins and discrete component leads, and can automatically set test parameters for each pin. This eliminates the hassle of individually programming solder amounts and short-circuit windows for each pin, delivering a programming speed more than 5 times faster than competitors.
8. Powerful barcode recognition feature
It can automatically recognize 1D and 2D barcodes, and the barcode size is not limited by the field of view—providing customers with robust technical support for seamless quality traceability, making it not only practical but also intuitive and convenient.
9. Comprehensive SPC Statistical Functions
Complete industrial process control enables the export of statistical data, providing data support for the continuous improvement of production line quality.
10. Unique Intelligent Weight Analysis Method
Featuring a proprietary patented algorithm (Patent No. ZL 2009 1 0236019.5), this solution boasts robust fault-tolerance capabilities, enabling stable testing with just a few boards for training. It delivers exceptionally low rates of false positives and false negatives, while requiring no complicated parameter adjustments—making it effortless for every operator to master.
11. Patent-protected cardboard structure effortlessly handles borderless circuit boards (Patent No. ZL 2009 2 0105338.8)
Automatic clamping pallet structure for convenient handling of circuit boards; the distance between circuit board components and the board edge can be as little as zero, yet the system still handles it effortlessly—no additional fixtures or support plates required.
12. Automatic Duplex Function
The automatic duplex feature makes double-sided testing quick and effortless.
13. Unique size measurement feature
Expand beyond the original AOI testing capabilities to unlock greater potential for AOI. Accurately measure aperture sizes, groove dimensions, and areas of irregular shapes on PCB boards.
