EOL Test System

Overview:
End-of-Line test solution for 100% product validation before shipment ensuring quality and compliance
 
Project Description:
This project focuses on the design and development of an automated End-of-Line (EOL) testing system for final-stage validation of PCBAs and fully assembled electronic products under real operating conditions. The system integrates programmable instrumentation, custom test fixtures with pogo pins, and a PLC/PC-based control unit to execute predefined electrical and functional test sequences with high accuracy and repeatability. It also incorporates features such as pneumatic clamping, barcode-based traceability, and an HMI/software interface for real-time monitoring, result display, and data logging. The primary objective is to ensure 100% product validation, deliver clear pass/fail decisions, improve production efficiency, and minimize defects before shipment, making it a critical solution in modern automated manufacturing.
 
Key Features:
1.Complete automated end-of-line validation with configurable test sequences.
2.High-speed, high-accuracy electrical measurement and data acquisition.
3.Real-time monitoring, pass/fail indication, and detailed result logging.
4.Barcode/QR-based traceability for product tracking and quality control.
5.Pneumatic fixture integration for fast, reliable, and repeatable testing.
6.Modular and scalable architecture adaptable for multiple products.
7.User-friendly HMI/PC interface for easy operation and control.
8.Safety interlocks to ensure operator and equipment protection.
Test Coverage:
1.Power-up and full functional validation including operating modes and load conditions
2.Communication and interface testing (UART, I2C, SPI, CAN, network connectivity)
3.Analog and digital parameter verification (voltage, current, signals, performance)
4.Firmware, configuration, and user interface validation
5.Safety checks, diagnostics, and end-of-line reporting with traceability
