Page 7 Packing 5 www.soberton.com Soldering Condition We suggest using anti-static welding machine which can control soldering temperature automatically. EM ELECTRET CONDENSER MICROPHONE Acoustic Product Specification 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.
