How to Implement Barcode Scanning in ICT

+ Expert Parallel Test Systems

Automated Barcode Scanning Workflow

Barcode scanning in in-circuit test (ICT) environments requires integration of optical readers with conveyor systems and test handlers to capture printed circuit board (PCB) identification data. The setup involves positioning barcode readers either upstream on the conveyor or within the test zone, interfacing through serial communication ports, and configuring handler software to validate scanned data before executing test sequences.

The workflow includes detecting the PCB position, triggering the barcode reader, transmitting serial data to the test system, and validating serial number formats. Configuration steps include enabling barcode functions, assigning serial port instruments, defining communication parameters, and setting validation rules such as increment/decrement formats or automatic board version selection based on scanned identifiers.

Barcode Scanning Integration ICT Solution

Implementing barcode scanning requires integrating a barcode reader with the test handler system and configuring software to process serial data inputs. The solution includes flexible hardware placement options, allowing scanning either upstream before test entry or inside the test zone prior to execution. It supports serial port communication setup, barcode validation logic, and automated board version selection based on scanned identifiers. The system enables configurable scan timing, validation rules, and seamless interaction with test plans. It also supports troubleshooting accessibility, flexible reader positioning, and controlled workflow execution. This approach improves traceability and reduces manual intervention in high-volume manufacturing environments while maintaining consistent test sequencing.
