Cost Reduction and Efficiency Improvement through Self-Repair of Circuit Boards
Recently, the operation area of the rolling operation department at the Anyang base successfully eliminated electrical hazards through self-repair of circuit boards, ensuring the normal operation of various precision equipment control components and saving the company external repair costs.
During the annual overhaul of the rolling operation department, maintenance personnel discovered that multiple circuit boards in the 6RA80 DC speed regulation systems had several capacitor swelling and deformation issues, which severely affected production. The circuit board, as a key control component of various precision equipment, plays a crucial role in the normal operation of the equipment. In the past, when a circuit board malfunctioned, it could only be sent to external professional institutions for repair. This method not only resulted in long repair cycles, leading to prolonged equipment downtime and severely impacting overall production progress, but also incurred high repair costs.
To solve this problem, the operation area quickly assembled a team of experienced and skilled electrical engineers from within to tackle the circuit board repair. In the electrical room, the repair technicians, dressed in gray uniforms and wearing safety helmets, stood in front of the distribution cabinet, their eyes focused on the flashing indicator lights on the cabinet. The probes of the multimeter in their hands carefully touched different circuit nodes, measuring voltage and current values, while a young assistant beside them held a notepad in one hand and a pen in the other, ready to record data at any moment. The team members proactively gave up their break time and dedicated themselves to intensive repair study and practice. They delved into the circuit principles and chip technologies of various circuit boards, conducting repeated experiments by disassembling old circuit boards to familiarize themselves with the functions and characteristics of each component.
Faced with this circuit board failure, the repair team quickly diagnosed the cause as multiple damaged capacitors, thanks to their superb skills and seamless collaboration. They then carefully removed and replaced the capacitors and meticulously repaired the short-circuited circuit.
After relentless efforts, the team successfully overcame the technical challenges, restoring normal operation of the equipment in just 8 hours. Compared to previous external repairs, the time was significantly shortened, greatly reducing equipment downtime and effectively improving production efficiency. Additionally, it saved substantial external repair costs. Statistics show that self-repair of circuit boards can save repair costs of over one hundred thousand yuan annually.
