RECOMMENDED CUSTOMER LAND PATTERN K nowles Acoust ics, a division of Knowles Elect r onics, LLC. Revision: B 5 of 11 SP0208LE5 8. RECOMMENDED SOLDER STENCIL PATTERN          š     Notes: • • • • The design requires that an acoustic seal be established between the SiSonic and customer PCB. This is accomplished via a solder seal. Solder Stencil Thickness = 0.127 min to 0.178 max Stencil Material = Stainless Steel * Ø1.50 reference to maximum metal opening in customer PCB.

Test Thermal Shock Description Microphone unit must operate when exposed to air-to-air thermal shock 100 cycles, from –40ºC to +125ºC. (IEC 68-2-4), Microphone unit must maintain sensitivity after storage at +105ºC for 1,000 hours. (IEC 68-2-2 Test Ba) Microphone unit must maintain sensitivity after storage at –40ºC for 1,000 hours. (IEC 68-2-1 Test Aa) Microphone unit must operate within sensitivity specifications for 1,000 hours at 105ºC. (IEC 68-2-2 Test Ba) High Temperature Storage Test Low Temperature Storage Test High Temperature Operating Test Low Temperature Operating Test Humidity Test Vibration Test Microphone unit must operate within sensitivity specifications for 1,000 hours at –40ºC. (IEC 68-2-1 Test Aa) Tested under Bias at 85ºC/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 20g (+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 260ºC for 30 seconds maximum. Microphone must operate after exposure to shock test of 10,000 G per IEC 68-2-27, Ea. Electrostatic Discharge Reflow Mechanical Shock K nowles Acoust ics, a division of Knowles Elect r onics, LLC.
