automated optical inspection machine



Delivery Time:28 days


AOI automated optical inspection machine use visual methods to monitor printed circuit boards for defects.They are able to detect a variety of surface feature defects,PCB optical detector can replace the visual check and manual operators.

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.

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.
