Testing system, crack noise monitoring device and method for monitoring crack noise

A crack noise monitoring device suitable for detecting whether a semiconductor element being tested on a testing apparatus is cracked, and the crack noise monitoring device comprising:

• a database unit comprising at least one first voiceprint pattern;
• a voiceprint generation unit configured to receive a sound wave and convert the sound wave into a second voiceprint pattern;
• and
• a sound conduction set electrically connected to the voiceprint generation unit for transmitting the sound wave to the voiceprint generation unit, the sound conduction set comprises a solid conductive vibrator directly connected to an element pickup module of the testing apparatus, and configured to receive vibration generated from the semiconductor element via the element pickup module;
• a sound guide tube respectively fixedly connected to the voiceprint generation unit and the solid conductive vibrator;
• and a diaphragm disposed within the sound guide tube, and configured to convert the vibration into the sound wave and transmit the sound wave to the voiceprint generation unit, wherein the sound wave is sent from the semiconductor element to the sound conduction set via the testing apparatus;
• and
• a processing unit electrically connected to the voiceprint generating unit and the database unit for comparing the at least one first voiceprint pattern and the second voiceprint pattern to determine whether the at least one first voiceprint pattern is identical to the second voiceprint pattern.

A method for monitoring crack noise, suitable for detecting whether a semiconductor element being tested on a testing apparatus is cracked, and the method comprising:

• providing at least one first voiceprint pattern;
• receiving vibration generated from the semiconductor element via the testing apparatus through a solid conductive vibrator directly connected to an element pickup module of the testing apparatus;
• converting the vibration into a sound wave through a diaphragm disposed within a sound guide tube;
• converting the sound wave into a second voiceprint pattern;
• comparing the at least one first voiceprint pattern and the second voiceprint pattern to determine whether the at least one first voiceprint pattern is identical to the second voiceprint pattern;
• and
• when it is determined that the at least one first voiceprint pattern is identical to the second voiceprint pattern, issuing an alarm outwardly.
