Product technical features
1. Mounter data import function
The data of the placement machine can be used to automatically generate programming data, which can greatly improve the programming speed.
2. Asynchronous manual discrimination operation
The operator's judgment is carried out synchronously with the machine test , and the test situation of the first 20 boards can be seen, which can be used in conjunction with the automatic front and back function to greatly improve the detection speed.
3. Select the MA RK point arbitrarily
In addition to the traditional circular, rectangular, cross, and triangular marks as MARK points, any characteristic marks can also be used as MARK points. Up to 3 spare MARKers can be selected to ensure board positionability
4. Powerful detection capability of lithography resistors
Powerful automatic adjustment function, even for very dark lithography resistors, you can deal with it freely without adjusting the light.
5. Discrete component color ring test
The industry-reliable color wheel component testing technology can automatically remove the influence of light and extract the color wheel color information for testing.
6. Any angle measurement method
All component, foot, solder and bridge tests can be tested at any angle.
7. Automatic segmentation of IC pins and discrete component solder pins
Automatically divide IC pins and discrete component solder pins and automatically set test parameters for each pin. It avoids the trouble of programming the solder volume and short-circuit window one by one, and the programming speed is more than 5 times faster than that of the peers.
8. Powerful barcode recognition function
It can automatically identify 1D and 2D barcodes, and the barcode size is not limited by the size of the field of view.
9. Perfect SPC statistical function
Complete industrial process control can export statistical data to provide data support for continuous improvement of production line quality.
10. Unique intelligent weight analysis method
Unique patented algorithm (patent number ZL 2009 1 0236019.5 ), powerful fault tolerance, only need to train a few boards to test stably, extremely low false positive rate and missed call rate, no complicated parameter modification, make each operation Workers can easily deal with it.
11. The card board structure of patented technology can easily deal with the edgeless circuit board (patent number ZL 2009 2 0105338.8)
The automatic clamping card structure is convenient for picking and placing the circuit board; the distance between the circuit board components and the edge of the board can be easily handled without additional fixtures or pallets.
12. Automatic front and back function
The automatic front and back function makes double-sided testing easy and simple.
13. Unique size measurement function
Break through the original AOI test project and let AOI play a greater role. Accurately measure the aperture size, groove size, irregular shape area, etc. on the PCB board.
