What are AOI machines?
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).
What is AOI in manufacturing?
AOI is an automated visual inspection methodology used primarily to test for defects in printed circuit board assemblies (PCBAs).
What is AOI in PCB design?
AOI, automated optical inspection is a particularly successful method for inspecting printed circuit board, PCB assemblies once they have passed through a soldering process. AOI is able to detect defects including solder joint problems and as well as a variety of other problems.
What does AOI mean in English?

What is SMT visual inspection?
a. Visual Inspection Along SMT manufacturing line, visual inspections are usually applied after solder paste printing, before reflow soldering and after reflow soldering among which the visual inspection carried out prior to reflow soldering is of the most significance when it comes to SMT assembly quality guarantee.
Do visuals do inspections?
A visual inspection is an inspection of an asset made using only the naked eye. This kind of inspection does not necessarily require any special equipment, but it does require special training so that the inspector knows what to look for as they visually review the asset.
What Colour is Aoi?
When you’ve just started to learn Japanese, you might notice this: the Japanese adjective for blue and green is the same: あおい (or 青い). Even in modern times, the word “aoi” is used to describe objects that are, well, green.
What is Aoi in history?
Area of interest, a contiguous area that is of interest for military purposes, related to area of responsibility.
Where is an AOI used?
printed circuit boards
Automatic or automated optical inspection, AOI, is a key technique used in the manufacture and test of electronics printed circuit boards, PCBs.
What is AOI logic?
AND-OR-invert (AOI) logic and AOI gates are two-level compound (or complex) logic functions constructed from the combination of one or more AND gates followed by a NOR gate.
What is ICT in SMT?
Ciruit Testing (ICT) ICT detect manufacturing defects by testing electrical properties, including Bed of Nails Tester and Flying Probe Tester. The primary advantages of ICT are rapid testing of short and open circuits, high defect coverage, and ease of programming.
What is SMT testing?
Process Inspection during SMT Assembly. Process inspection during SMT assembly is used to test the performance, analyze and deal with defects, including solder paste printing, chip mounting and reflow soldering.
How accurate is human visual inspection?
Unfortunately, according to the FMEA (Modal Analysis of Failures and Effects) inspection process guidelines, the “human visual inspection” is effective, reliable in only 80% of cases based on the observation of multiple factors such as different points of sight or operators, reduced cycle time, visual fatigue and …
