Stage Pre-heat Solder Melt Peak Notes: * Temperature Profile 170 ~ 180 C Above 230 C 260 C maximum Time (maximum) 120 sec. 100 sec. 30 sec. * * Do not pull a vacuum over the port hole of the microphone. Pulling a vacuum over the port hole can damage the device. Do not board wash after the reflow process. Board washing and cleaning agents can damage the device. Do not expose to ultrasonic processing or cleaning. Number of Reflow = recommend no more than 3 cycles. 11. ADDITIONAL NOTES (A) Packaging (reference SiSonic_Packaging_Spec.pdf) (B) Shelf life: Twelve (12) months when devices are to be stored in factory supplied, unopened ESD moisture sensitive bag under maximum environmental conditions of 30C, 70% R.H. (C) Exposure: Devices should not be exposed to high humidity, high temperature environment. MSL (moisture sensitivity level) Class 2. (D) Out of bag: Maximum of 90 days out of ESD moisture sensitive bag, assuming maximum conditions of 30C/70% R.H. Knowles Acoustics, a division of Knowles Electronics, LLC Revision: PRELIMINARY Page 7 of 9 SPM0204UD5 12. RELIABILITY SPECIFICATIONS Note: After test conditions are performed, the sensitivity of the microphone shall not deviate more than 3dB from its initial value. Test Description Thermal Shock High Temperature Storage Test Low Temperature Storage Test Microphone unit must operate when exposed to air-to-air thermal shock 100 cycles, from -40C to +125C. (IEC 68-2-4), Microphone unit must maintain sensitivity after storage at +105C for 1,000 hours. (IEC 68-2-2 Test Ba) Microphone unit must maintain sensitivity after storage at -40C for 1,000 hours. (IEC 68-2-1 Test Aa) High Temperature Operating Microphone unit must operate within sensitivity specifications for 1,000 hours at Test 105C. (IEC 68-2-2 Test Ba) Low Temperature Operating Test Humidity Test Microphone unit must operate within sensitivity specifications for 1,000 hours at - 40C. (IEC 68-2-1 Test Aa) Tested under Bias at 85C/85% R.H. for 1,000 hours. (JESD22-A101A-B) Microphone unit must operate under test condition: 4 cycles, from 20 to 2,000 Hz in each direction (x,y,z), 48 minutes, using peak acceleration of 20 G (+20%, -0%). (MIL 883E, method 2007.2, A) Tested to 8kV direct contact discharge to the case and tested to 2kV direct contact to I/O terminals. Microphone is tested to 5 passes through reflow oven, with microphone mounted upside-down under conditions of 260C for 30 seconds maximum. Microphone must operate after exposure to shock test of 10,000 G per IEC 68-2-27, Ea.
