Fortemedia Launches a Cutting-Edge MEMS Microphone Solution Which Meets the Stringent Air Pressure Requirements

Reliability is always one of the key success factors to gain customer satisfaction in microphone products which will be equipped and used in various environmental conditions. There are frequent challenges and risk to damage microphone physically or degrade the acoustic performance in the process of MEMS microphone’ mass production and its final assembly of end products. For example, dust obstacle, oil stain, electrostatic discharge damage in the machine or accidentally by humans, and material defects due to thermal cycle during the reflow soldering . Therefore, the robustness is always Fortemedia’s quality target regardless of users’ misuse or careless operating for its MEMS microphone solution. With professionally persistent efforts in design, validation, characterization, and quality assurance in manufacturing , Fortemedia’s microphone solution composed of the IC and MEMS sensor insides passes the following stringent reliability test in the industry:

• HAST (Temperature with Humidity with Bias)
• Drop Test
• Mechanical Shock Test
• Vibration Test
• Accelerated Life Test
• Air Pressure Test

Air Pressure Requirement:

Regarding air pressure immunity, Fortemedia has launched MEMS microphone solution that can achieve the harshest requirements of air pressure in field. Packaged in 2.75×1.85×0.90mm³ microphone footprint & 0.25mm aperture, Fortemedia’s microphone IC, FL216C and MEMS sensor, TMS02BD has passed tier-one customer’s air pressure test conditions, making Fortemedia the pioneer vendor upon global OEM’s high-standard acceptance. Other than passing air pressure requirement, Fortemedia’s microphone solution also passed industrial stringent reliability test. Besides that, Fortemedia’s IC and MEMS sensor also provide the tight variation of phase matching and sensitivity matching, facilitating Fortemedia’s voice processing in performance, quality and consistence.
