Product General Information

Place of Origin:

Brand Name:HE CAN
Model Number:A3


1.International first-line brand accessories to ensure the accuracy of equipment operation.

2. It can be operated remotely.

3. Rrgb coaxial LED light source is designed independently to ensure the uniformity of light. 

4. A variety of algorithms, easy to deal with complex detection environment.

5. Bending automatic compensation function, flexible plate detection is also excellent.

6. SPC data statistics, the same error occurs many times automatic alarm, so as to remind the improved production process.


It is an automatic optical inspection equipment which is based on the optical principle to detect common defects encountered in welding production. AOI is a new rising test technology, but it is developing rapidly. Many manufacturers have launched AOI test equipment. When automatic detection, the machine automatically scans PCB through camera, collects images, compares the tested solder joints with qualified parameters in database, and after image processing, it checks out defects on PCB, and displays / marks defects through display or automatic marks for maintenance personnel to repair.


1. Higher degree of automation, suitable for testing single products, large single quantity, stable quality products.

2. It is suitable for on-line inspection before and after the furnace.


Applicable scenarioSMT furnace front and rear detection
Detection algorithmTOC、Histogram、Match、Short、Other、PIN, etc.
