What to learn to be an AOI engineer 50

AOI stands for Automatic Optical Inspection

Current mainstream AOI:

1.By its use, it can be divided into two categories:

Before Reflow Oven: Check whether the components on the PCB are properly mounted.

After Reflow Oven: Check whether the components on the PCB are mounted and soldered properly.

2.By how it works, it can be divided into three main categories:

1) Gray scale (0-255), artificially divided into 256 intervals, 0 is the blackest, 255 is the brightest. Classics such as Agilent SJ.

2) Trichromatic light (RGB), the composition of the three primary colors of light, namely: red, green, and blue. Classics such as omron

win2，rns。

3) Image contrast, as the name suggests, is a pure comparison between images. Classics such as mirtec

To be an AOI engineer, you need to learn a lot, and it is the key to improve the yield rate and reduce the leakage rate.

PS: To learn the industry standard: IPC-A-610D, as well as the analysis tool SPC.

optical

Inspection) is an automated optical inspection instrument, and the AOI engineer is the engineer responsible for the maintenance of this equipment.

ICT** test, ICT, in-circuittest, is a standard test method to check manufacturing defects and defective components by testing the electrical properties and electrical connections of first-class components. It mainly checks the open and short circuit of a single component and each circuit network, and has the characteristics of simple operation, fast and rapid, and accurate fault location.

An ICT engineer is an engineer who is responsible for programming, commissioning, and maintaining ICT equipment.

This is not something that can be done by relying on information.

It makes a big difference whether you're doing a service or an application or a developer.

Scope of work:

1.By its use, it can be divided into two categories:

Before the furnace: Check whether the component placement on the PCB is normal.

After the furnace: check whether the component placement and soldering on the PCB are normal.

2.By how it works, it can be divided into three main categories:

1) Gray scale (0-255), artificially divided into 256 intervals, 0 is the blackest, 255 is the brightest. Classics such as Agilent SJ.
