What is Aoi in SMT?

Automated optical inspection (AOI) is one of the best inspection tools in the SMT environment. It helps identify issues and defects in the early stages of the manufacturing process.

What is 3D AOI?

3D AOI methods serve as an effective tool for volumetric and coplanarity inspections. These inspection methods can provide details on the height information of lead tips, BGAs,chip components, reflowed solder fillets or, essentially, critical dimensional information on any height sensitive component.

What is the purpose of AOI?

AOI is an automated visual inspection methodology used primarily to test for defects in printed circuit board assemblies (PCBAs). AOI autonomously scans PCBAs with cameras and detects two types of failures: 1. catastrophic failures, such as missing components, and 2.

What does AOI stand for?

AOI

Which is machine vision system does ViTrox use?

ViTrox is specialized in machine vision system (MVS), automated optical inspection (AOI), and automated X-ray inspection (AXI) system.

How does automated optical inspection ( AOI ) work?

Automated optical inspection ( AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew).

When to use Aoi in the manufacturing process?

It is implemented at many stages through the manufacturing process including bare board inspection, solder paste inspection (SPI), pre-reflow and post-reflow as well as other stages. Historically, the primary place for AOI systems has been after solder reflow or “post-production.”

How many offices does ViTrox have in the world?

ViTrox is specialized in machine vision system (MVS), automated optical inspection (AOI), and automated X-ray inspection (AXI) system. Currently, there are total of 8 offices branches across the globe. ^ “Annual Report”.
