Case Overview

A customer’s Raycus fiber laser suddenly failed during operation due to a burned control board and a damaged QBH connector, resulting in complete production downtime. Instead of replacing the entire laser source, CINA Laser provided a seamless repair and upgrade solution by integrating a fully compatible control board system, restoring the machine quickly and cost-effectively.

Before Repair

  • Control board burned, system could not start
  • QBH connector damaged, no laser output
  • Machine completely shut down
  • Production halted, causing significant delays
  • High cost risk if full laser replacement required

Repair Process

  • Full system diagnosis to identify control board failure and QBH damage
  • Removal of the burned Raycus control board
  • Installation of CINA Laser compatible control board (plug-and-play)
  • Repair and stabilization of QBH connector interface
  • System parameter calibration and optimization
  • Output testing and stability verification

After Repair

  • Laser output fully restored
  • Stable and continuous beam performance
  • No modification to original machine required
  • System runs smoothly with upgraded control board
  • Production resumed immediately
