Product description

Feature of PCB Industrial Solutions SMT AOI Machine:

1. Intelligent double conveyor structure design, the machine with the customer's double conveyor reflow or mounting machine seamless docking, cuts down the consumption.

2.According to the customer's own production demands to choose the double conveyor single vision system or double conveyor two vision system configuration.

3. double conveyor programs can be free to switch & combination to respond to different production needs.

4.Two sets of inspection system can share the database, can output the SPC report.

Easy to operate and multi-function AOI

Different AOI model can be placed at several quality controlling points in SMT line such as to check 2D paste printing quality, check component defects before reflow soldering, check PCBA quality after reflow soldering, and DIP after wave soldering.

Double conveyors design


*The first and the fourth conveyor fixed, the second and the third conveyor are adjustable: the inspection size between:50×50mm~510×280mm .

*Can customize double conveyors or other more functions according to customer's different request


Add professional character recognition function (OCR/OCV) further enhance the testing precision;


The new function first potential PPK analysis process and statistical analysis P-BAP chart can get offset value after reflow, which provide accurate effective reference material for process improvement.

Both double conveyors single head and double heads AOI are pioneered by us


*Both double conveyors single head and double heads AOI are pioneered by us, which can joint with other front and rear equipment in SMT seamlessly, save load and unload time to carry out continuous operation to improve productivity

*Meanwhile, this equipment can choose a variety of light source using high-speed digital camera to achieve the highest detective capability. This can be placed in multiple stations of SMT line for inspecting such as after print, before reflow and after reflow.

Offline Debugging


The offline programming software can connect multiple online testing AOI and carry out program debugging without halt to improve efficiency.

Database sharing and statistical functions



All internal AOI are managed via central server, all single machines are in remote control. SPC reports will be generated through collection and analysis of all data to promote process improvement and improve products passing rate.

Detailed SPC Analysis Report



To generate a variety of visual reports through analysis and statistics from testing results of all products.
