In the production of PCB boards, the way of jigsaw boards will be adopted. A jigsaw board is composed of multiple small PCB boards. Each PCB board will be pasted with a barcode or a QR code, and on this jigsaw board there will be a piece covering the entire piece. The radium-engraved QR codes for the panel information are small in size and rich in content. The surface of the printed material is uneven and sometimes has problems such as reflections.

When collecting the above-mentioned PCB board information, an automated industrial scanning module is often used to scan all the barcode and QR code information of the entire board at one time and transmit it to the background. This has very high requirements for the scanning module. The following is a video of the XTID5200M industrial scanning module scanning the barcodes and QR codes of 10 panels in batches:
