Machine Vision System for Quality Control

Enhancing Defect Detection and Product Traceability with AI-Powered Machine Vision

Client Overview

A leading electronics component manufacturer based in Southeast Asia, known for its high-volume production of microchips and PCB assemblies. The company sought to minimize human error in quality checks and improve traceability without slowing down the assembly line.

Our Approach

Qematic began with a Time and Motion Study Audit of manual visual inspection tasks to determine throughput limits and human error factors. We then deployed a machine vision system tailored to high-volume electronics production.

Steps included:

  • Identifying critical inspection points across the assembly line
  • Setting up multi-angle industrial cameras for micro-inspection
  • Training AI models to detect over 50 defect types
  • Integrating barcode and RFID scanning for traceability

Challenge

Manual quality control processes were causing:

Machine Vision

Business

India

Location

Key pain points included:

  • Inconsistent defect detection
  • Delays in production due to visual inspection bottlenecks
  • Missed micro-level defects, leading to increased returns
  • Limited traceability of rejected batches
  • High operational cost for quality assurance
