📂 【Technical Diagnosis | Case #02】
The failure point of this megaphone was more critical than expected. The copper foil on the microphone unit had completely peeled off—a situation usually deemed "irreparable." In this episode, we tackle the challenge of reconstructing the copper foil and performing micro-soldering to restore signal conductivity.
This channel features real-world teardowns performed by a professional hardware engineer (10+ years exp.), demonstrating practical diagnostic logic and decision-making used in actual repair scenarios. The goal is to identify true root causes and avoid unnecessary part replacement or misdiagnosis.
