Automated Optical Inspection (AOI)

No product leaves Active-PCB Solutions without passing a rigorous inspection. Every PCB assembled on our SMT line is thoroughly inspected using our Koh Young Technology KSMART 3D Automated Optical Inspection (AOI) system with live data streaming, which tracks each board throughout the assembly process ensuring no defects go undetected. The quick error detection means that issues are spotted and corrected instantly, resulting in faster turnaround times and enhanced product quality.

Automated Optical Inspection (AOI) for PCBs | Active-PCB Solutions

In electronics, precision is everything. With the rising complexity of electronics and demand for flawless production, ensuring that each PCB meets exacting standards is essential. That’s where our Automated Optical Inspection (AOI) technology comes in, providing advanced, non-contact inspection that catches defects early in the production process and ultimately saving time, reducing waste, and ensuring the highest quality for our clients.

What is Automated Optical Inspection (AOI)?

Automated Optical Inspection (AOI) is a cutting-edge technology used to inspect PCBs during various stages of manufacturing. AOI systems use high-resolution cameras and advanced imaging algorithms to capture detailed images of PCB assemblies. By comparing each assembly to a pre-defined standard, the AOI system can quickly detect issues like misalignments, soldering defects, missing components, and other critical flaws that could potentially lead to product failures.

At Active-PCB Solutions, we utilise state-of-the-art Koh Young AOI systems with Altus Group KSMART software, that provide rapid, accurate, and repeatable inspections, ensuring each board meets quality requirements before it moves to the next production stage.

How AOI Enhances PCB Quality and Reliability

  1. Early Detection of Defects
    AOI systems enable us to detect defects at an early stage, reducing costly rework and preventing issues from reaching later stages in the assembly process. By identifying potential problems early, we can halt the assembly to make immediate corrections, improving both yield and quality.
  2. Precision and Consistency
    Our AOI systems are designed to identify even the smallest deviations from design specifications, such as minor soldering imperfections or component misplacements. This precision translates into consistently high-quality PCBs, which is essential for industries like automotive, medical devices, telecommunications, and aerospace where reliability is paramount.
  3. Enhanced Throughput
    With automated inspection, Active-PCB Solutions can ensure a high throughput without compromising on quality. AOI systems operate at high speeds, allowing us to maintain efficiency even with large-volume orders. This automated inspection process minimizes bottlenecks and optimizes the entire production workflow.
