During the mass assembly of printed circuit boards for mobile phones, cameras and other acoustic devices, there are some technical issues that may jeopardize the integrity of MEMS acoustic films, including high temperatures during the reflow process. The resulting pressure build-up, particulate contamination, and atomized solder droplets can damage MEMS microphones, resulting in reduced acoustic performance of electronic devices, lower yields, and higher manufacturing costs. Therefore, dust shielding and pressure balancing are urgent performance requirements that need to be addressed in MEMS microphone production. MEMS acoustic membrane design solutions based on Expanded PTFE membrane technology are proven to prevent particle contamination and pressure build-up, support in-process acoustic testing, and can be seamlessly integrated into automated pick and place During the packaging process; at the same time, due to the excellent hydrophobic properties of expanded polytetrafluoroethylene membrane, in addition to particle protection and pressure balance, component-level IP68 water immersion protection can also be achieved by relying on the integrated design of the package. .
A smartphone is generally equipped with 3-5 MEMS microphones and 1-2 TWS earphones, and smart homes are mainly equipped with The number of interactive product smart speakers reaches 2-8. In addition, wearable devices have a greater demand for low-power, small-sized MEMS microphones.
The expanded polytetrafluoroethylene membrane product produced can achieve IP67 or higher hydrophobicity. In addition, the membrane has good rigidity, moderate density and sound insulation. The sound loss is small and can be widely used in hydrophobic digital cameras, walkie-talkies, smart watches, handheld ultrasound machines, handheld navigators, smart water cups, children’s smart early education machines, speakers, earpieces, speakers, microphones, MICs, receivers, and buzzers. Devices etc. After years of painstaking research and development, the company not only has strong R&D strength, complete testing methods and domestic advanced experimental equipment, but also attracted a large number of outstanding technical talents.
