Soldering temperature should be controlled under 320 and soldering time for each terminal should be 1~2 sec.. 2. Microphone should be fixed on the metal block (heat sink), which has high radiation effects, and heat sink shall contact with MIC tightly. 3. Microphone may easily be destroyed by the static electricity. All countermeasure for eliminating static electricity must be executed (worktable and human body shall be ground connection) Shape of Shape of hole at fixed part Heat Sink heat sink Schematic Drawing R = 680 L Packaging V = 1.5 V S C 1 F 1.1 Anti-Static Bag Parts Construction Materials Name Material QTY 1.2 Small Box 1 Dustproof gauze 1 100 Parts 2 Case Al-Mg Alloy 1 Diaphragm DUPONT 3 1 4 Spacer 1 Electret Plate Copper blank 5 X 60 Housing Chamber 6 1 7 PCB FR4 1 1.3 Middle Box FET 8 1 6,000 Parts 9 PC Pins 2 Testing Procedure X 2 1.4 Shipping Carton 12,000 Parts 4.
