Product Details

Automatic optical inspection machine, AOI, is a key technique used in the manufacture and test of electronics printed circuit boards, PCBs. Automatic optical inspection system, AOI enables fast and accurate inspection of electronics assemblies and in particular PCBs to ensure that the quality of product leaving the production line is high and the items are built correctly and without manufacturing faults.

ASCEN A500 model 3D Offline AOI is designed for inspection of PCB with top component clearance upto 50 mm. the A500 model is very suitable for a standard PCB inspection after reflow oven . In addition, the same machine can inspect components on glue including the pad glue contamination.

A500 PCB optical inspection machine was built as an entry level machine for customers requiring a high-quality AOI with low price. This machine offers easy and straight forward programming, ultra-fast inspection speed, very high detect ability and low false alarm rate.A500 3D Offline auto optical inspection system supports central server and library configuration, offline programming and verification. The standard configuration includes barcode reading with camera, on-system verification, SPC and tracibility.

About the AOI pcb auto optical inspection machine more application in the SMT assembly line, Please check the solution detail in the”How the auto optical inspection machine detect variety of surface feature defects for PCB board”

Automatic Optical Inspection Part Defect Cases:

Automatic Optical Inspection Machine Application Ability:

Programming speed

1)A PCBA with 3000 frames can be finished within 50 minutes by manual programming.

2)If it has component library, import CAD data to program automatically.

3)ASCEN AOI A500 model has OLP package(including offline debugging function)

Automatic optical detector Cycle Time

1)Test a PC motherboard in 15 seconds

2)Test a mobile phone board in 3 seconds

3)180 frames per second on average

Statistic Process Control (SPC)

1)Auto optical inspection machine providing reports in detail

2)Automatic warning when the same error occurs for times

3)Auto-count the pie chart,graph and PPM chart of week, month and quarter.

4)Seamless connection between SPC and AOI, take measures to avoid problems

According to the feedback, then it will control the quality in time.

Ability Source

1)Intellectualized digital color camera

2)Extra bright RRGB coaxial ring tower LED light(color light)

3)Multi-algorithm to different test items

PCB optical detector

Acculite patent coaxial light (Developed to flip and unsoldered)

With coaxial four-level illumination, the parts can be in the best status of brightness and softness. A500 model is able to test HASL and red glue efficiently to improve solder image quality of after reflow and inspection results. It helps to solve the solder joints problems caused by PCB with different background colors.High precision intellectualized camera reads the barcode automatically, providing high speed and clearer images.
