6 Steps of Automated Optical Inspection (AOI) Program

Blog Article

AOI is the shortened form of Mechanized Optical Assessment. The fundamental capability of automated optical inspection equipment to trade manual assessment for different deformities in PCB. AOI plays a proficient, exact, efficient, and cost-saving job inthe  PCB line. The nature of the Robotized Optical Investigation (AOI) program straightforwardly chooses the presentation of AOI. Numerous clients want to know how to start an AOI program. In this post, we will introduce bit by bit.

Pass System Supply, which gives Research and development, deals,s and after-deals administration of AOI. 

 

There is 6 moves toward setting up another program in AOI:


  1. Lay out Another Program

  2. Properties Setting

  3. AOI setting

  4. Alter Program

  5. Troubleshooting

  6. Examination


The initial three stages are straightforward. For an accomplished developer, the initial three stages of a mechanized optical examination program can be finished in three minutes or less. The fourth step of the AOI program and the fifth step of troubleshooting are troublesome, which are key stages in the entire program set up in AOI. These two stages require more practice to be a certified AOI engineer.

Stage 1. Lay out Another program


In this step, you just snap on 'new' and give a name to your new program.

Stage 2. Properties Setting


In this step, you will set the size of the PCB in the AOI program. It will be satisfied naturally after you move the crossline to two corners of the PCB. Then the program will create the outline image of the PCB in a test.

Stage 3. AOI Setting


AOI setting has four primary capabilities:

  1. Check stacked PCB board is compared to its program;

  2. Check which side of PCB is reviewing (A/B side), naturally utilize comparing program;

  3. Check assuming the PCB board position is right;

  4. Review the distortion during the reflow broiler.


In this step, you ought to find two-person positions on PCB. Thus, the program will track down them on the PCB in the assessment.

Stage 4. Alter program in Robotized Optical Review Program


Program Altering has two strategies, manual programming and computer-aided design information programming. The two strategies require standard enrollment of all parts on the PCB.

Manual writing computer programs is an enrollment or connecting standard for parts on the PCB. The adaptability isn't high. After the programming finish, we ought to check the program to be cautious. Since perhaps there are missing parts that are not enrolled.

Computer-aided design information programming should accept computer-aided design information prior to doing the program. Software engineer just has to enroll the related part concurring the part number, which is more programmable. In any case, during the time spent doing the program, the part outline drawn should be erased in computer-aided design information programming. The effectiveness is diminished, and manual writing computer programs don't experience such difficulty.

Here, we suggested computer-aided design information programming, assuming there are in excess of 50 parts on the PCB. assuming the parts on the PCB are under 50, we suggested manual programming.

 

5. Troubleshooting


There are 3 primary investigating modes:

Auto-Learning Mode: The program becomes familiar with an enormous number of standard PCBs by factual demonstration. The speed of which is fast and the presentation is great.

Mistake Delay Mode: The program will stop for each single investigated issue on PCB. A designer will troubleshoot mistakes individually.

Auto-Situating mode: the program will change the part position naturally in the permitted range, to get better learning results.

The fundamental stages of the troubleshooting:

After we enhance the focal point, select the Auto-Situating mode and let the program run multiple times.

Select Auto-Learning Mode. set learning limit to multiple times, immediately Mode, and Auto-Situating mode. Allow the program to run one time.

Select the Mistake Delay Mode, without Auto-Learning Mode and Auto-Situating Mode. Allow the program to run one time.

Load the Second PCB board, increment the limit worth to 40, and rehash the activity 2.

Rehash activity 3.

Load the third PCB board, increment the limit worth to 60, and rehash activity 2.

Rehash activity 3.

Load the fourth PCB board, increment the limit worth to 80, and rehash activity 2.

Rehash activity 3.

Load the fifth board and increment the limit worth to 100. Rehash activities 2 and 3.

Load Nth board and increment the limit worth to 20N. Rehash activities 2 and 3.

Rehash activity 11 until the program becomes steady.

6. Review


Unselect the Mistake Interruption Mode, Auto-Learning Mode, and Auto-Situating Mode.

Click the begin to start Assessment.

End


Typically, there are 6 moves toward finishing a mechanized optical examination program. 1. Establish Another Program. 2. Properties Setting. 3. MARK setting. 4. Alter Program. 5. Investigating and 6. Review. After these steps, we can run an AOI in our PCB mechanical production system.
