Something About Automated Inspection Systems

Automated Optical Inspection (AOI) is as the name suggests a visual quantitative and qualitative test for PCBs. This automatic process allows companies to reduce their dependency on manual testing and thereby lessen any chances of human error. Since testing is an important process when it comes to the products provided by PCB assembly service providers, AOI systems offer immense reliability.

 

Need for Robust Testing Systems

PCBs need to be produced according to certain guidelines put forth by leading organizations and Government bodies. Some specific reasons to opt for AOI testing include:

  • AOI testing is an automated optical system. This machine scans the PCB for several types of defects. Defect detection is extremely accurate with the AOI system.
  • The AOI system is able to scan several PCBs in a short time period. This increases the overall efficiency of the development process.
  • These systems are able to easily test complicated circuits in short time periods as well. Since the testing system is able to easily check the circuitry. Any doubts related to its performance and reliability are taken care of during the testing phase.
  • AOI systems help in reducing costs by reducing time spent in the testing phase. With a more reliable product, product recall is also lower, which has a direct effect on the overall cost of the product.

 

Additionally, this system detects defects during the initial stages of production. Early error detection reduces the effort taken to rework a product helping in decreasing overall cost as well.

 

Scope of Defect Detection with AOI Systems

AOI systems are designed for comprehensive testing of PCBs. Below is outlined the scope of the factors tested by these systems:

 

  1. Soldering Defects
  2. Component Defects

Lifted lead

Component size

Missing component

Misaligned or misplaced component

  1. Others

Tolerance monitoring

Component & Circuit Alignment

Overall product consistency

 

There are several other benefits offered by AOI systems. When used during PCB production, they help in the production of a reliable product. Allowing you to maintain product quality consistently, these systems are useful for organizations looking to comply with international standards as well as provide a superior product to their clientele.
