As a critical electronic component of mobile phones, the PCB serves as the foundational support for proper device operation. In electronics manufacturing, components sourced from various suppliers exhibit varying quality levels. To ensure traceability, each part carries its unique "identification mark." For mobile phone PCBs, this typically consists of laser-marked QR codes. Scanning these codes provides full production data, safeguarding both manufacturers' and consumers' rights.
The barcode reader enables rapid data collection facilitating complete production status tracking and establishing one-to-one data correlation. This forms the foundational data acquisition for end-to-end PCB production traceability.
Key Specifications:
Efficiency & Accuracy: High-speed automated operation with contactless ive and contamination-free identification
Supported Code Type: 2D codes (Data Matrix)
Code Size: 4×4mm
Reading Field of View: 100mm (long edge)
Dynamic Decoding Speed: >50mm/s
Working Distance:
Customer Pain Points:
Mobile phone motherboards contain multiple QR codes that require mutual correlation. Most codes are located on metal surfaces, causing glare interference. Manual contact with PCBs risks sweat-induced oxidation and electrostatic discharge (ESD) issues.
Project Challenges:
1.Challenges in achieving accurate and stable code reading during mobile phone PCB production
2.Post-reflow soldering issues: QR codes become blurred with low contrast, while requiring simultaneous reading of multiple small-sized codes
3.100% data accuracy must be maintained
Solution Approach:
1.AI-powered decoding algorithm specifically optimized for miniature code reading, enabling stable long-range scanning of low-resolution barcodes
2.Precision recognition technology that reliably decodes currently unreadable complex barcodes
3.High-speed dynamic decoding support with throughput up to 1m/s
Model Selection:
Barcode readers are installed above the conveyor belt at each required production station in the mobile phone PCB manufacturing line. The conveyor transports completed PCBs to the "scanning position," where the reader:
1.Scans QR codes on each PCB
2.Correlates decoded data with current station operation data
3.Uploads integrated information to the MES system
Recommended Model: R-3350
Quantity: 1 unit
Advantages:
With the 2D Ultra algorithm combined with precision positioning technology, even QR codes with damaged, blurred, or distorted positioning patterns can be located and read efficiently. The RegemMarr R-3000 series code readers feature a wide reading range and compact size for easy installation. They support multiple scanning modes including software triggering, external triggering, and free-running operation.
