ESR / TECHNOLOGY
How We Diagnose
Measurements that make the fault visible.
OSCILLOSCOPESIGNAL ANALYSIS
CAPABILITIES
Measurements reveal the cause of failure.
Every measurement helps confirm the fault and verify the repair.
Thermal imagingHot nodes · short-circuit area · thermal imbalance
Stereo microscopeSMD · solder joints · PCB damage · connectors
Signal analysisAudio · clocks · switching · ripple · instability
Load testingStability · protection · temperature · waveform
Soldering & reworkSMD · THT · connectors · damaged joints
Speaker workshopVoice coil · suspension · crossover · alignment
METHOD
Evidence before conclusion.
No single instrument proves every fault. ESR combines visual, thermal and electrical evidence with circuit context and final verification.
