Soldering Condition
We suggest using anti-static welding machine which can control soldering
temperature automatically.
Soldering temperature should be controlled under 320℃ 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. The countermeasure
for eliminating the static electricity shall be by grounding the worktable and
operator.
