Marking QR Code on Copper Foil

Marking QR Code on Copper Foil

Product catalog summary
Application Specifications:
The document outlines the specifications for marking a QR code using advanced light technology. The QR code is specified to be 8×18 cells in a matrix format, with each cell measuring 100um×100um and an interval of 150um. The entire marking operation must be completed within 10 seconds.
Technological Parameters:
The laser used is a 60W-LM1-L1, with a field lens of F=100mm. The filling type is dual rectangular, and the total operation time is noted as 12.5 seconds.
Marking QR Code on Copper Foil:
The document provides detailed parameters for marking a QR code on copper foil, divided into different stages: Punching, Marking 1, Marking 2, and Surface Cleaning. Each stage has specific settings for power, pulse width, speed, frequency, and filling density.
  • Punching: Power: 90%, Pulse Width: 250 ns, Speed: 300 mm/s, Frequency: 15 kHz, Filling Density: 0.003 mm.
  • Marking 1: Power: 37%, Pulse Width: 10 ns, Speed: 1000 mm/s, Frequency: 600 kHz, Filling Density: 0.02 mm (0°+90°).
  • Marking 2: Power: 25%, Pulse Width: 10 ns, Speed: 800 mm/s, Frequency: 800 kHz, Filling Density: 0.01 mm (0°+90°).
  • Surface Cleaning: Power: 50%, Pulse Width: 200 ns, Speed: 600 mm/s, Frequency: 400 kHz, Filling Density: 0.01 mm (0°+45°).
