EM ELECTRET CONDENSER MICROPHONE Soldering temperature should be controlled under 320℃ and soldering time for each terminal should be 1~2 seconds. Acoustic Product Specification Microphone may easily be destroyed by the static electricity. The countermeasure for eliminating the static electricity shall be by grounding the worktable and operator. Product Number: EM-4015-BC Microphone should be fixed on the metal block (heat sink), which has high radiation effects, and heat sink shall contact with MIC tightly.
