Static Barcode Reading for Smart Switch PCBs

Industry Demand

1.Component Installation:
Barcode scanning during PCB component mounting (ICs chips ARM-ded codes)

2.Soldering Process:
Post-soldering verification (LED chips PCB surfaces mounted components)

3.PCB Inspection:
Logistics tracking (carton labels packaged items)

4.Shipping QC:
Flex circuit codes & low-contrast marks on black resin substrates

Project Background:

During the production process of smart toilet switches, it is necessary to perform static reading of 2D label codes (QR Code) with a size of approximately 5mm×5mm. The code information is transmitted to the PLC via EIP communication, and the code data is compared and verified within the PLC to ensure real-time accuracy of the workpieces.

Barcode Reading Challenges:

1.When reading QR codes on labels attached to printed circuit boards, the small size of the codes, high module count, and low resolution place higher demands on the barcode reader.

2.Since there is potential for future modification to mobile reading, the system needs to support mobile scanning. Tests show it can capture and read some barcodes at 1 meter per second.

Solution Advantages

1.The compact R-3000 series barcode reader, when paired with adjustable-angle mounting brackets, significantly enhances operational flexibility and excels in various challenging applications. With optional multi-spectrum lighting and polarizing filters, it effortlessly handles reflective surfaces and low-contrast barcodes.

2.It supports high-speed dynamic decoding up to 1m/s.

3.Equipped with 2D Ultra algorithm incorporating precision search technology, it reliably locates and reads even QR codes with damaged, blurred or distorted alignment patterns.

Solution Performance:

The R-3000 series barcode reader supports high-speed dynamic decoding up to 1m/s, meeting future requirements for mobile scanning applications.

With its proprietary Ultra decoding algorithm, it easily captures problematic barcodes that were previously difficult to read—including wrinkled, damaged, or low-contrast codes—significantly improving scan reliability. The outstanding performance of the R-3000 series has earned consistent praise from both customers and on-site operators.
