electrostatic discharge
Tested to IEC61000-4-2 level 3
contact discharge
The microphone shall operate normally after 10 discharges to is 6KV DC and the discharge
network is 150pF & 330Ω.
air discharge
The microphone shall operate normally after 10 discharges to is 8KV DC and the discharge
network is 150pF & 330Ω
SOLDERING CONDITION
We suggest using an anti-static welding machine which can control soldering temperature automatically.
Soldering temperature should be controlled at under 320 °C and soldering time for each terminal should be 1~2 seconds.
Microphone should be fixed on the metal block (heat sink), which has high radiation effects, and heat sink shall contact
with MIC tightly.
Microphone may easily be destroyed by the static electricity and the countermeasure for eliminating the static electricity shall be
electrocution (worktable and human body shall be ground connection).
