SMDマイク

SMD electret condenser microphones are well-suited for compact, automated assembly environments. They are typically used in:

• Bluetooth speakers and wireless intercoms
• Smart home devices (e.g., voice-controlled systems, alarms)
• Wearables, lapel microphones, and portable recorders
• Conference systems and document cameras
• Consumer electronics requiring reflow-solderable components

Thanks to their reflow-soldering compatibility and omnidirectional pickup pattern, they are ideal for space-constrained, mass-produced electronics.

SMD electret microphones are based on traditional electret condenser technology but optimized for surface-mount applications. Here’s how they compare:

• Mounting: SMD mics are reflow-solder compatible, unlike traditional pin-type mics which require manual soldering.
• Thermal Resistance: Designed to endure SMT assembly with high-temperature tolerance (up to 260°C).
• Automation: Ideal for high-efficiency production lines due to their compatibility with automated pick-and-place equipment.
• Vs. MEMS: While MEMS mics are based on semiconductor processes, SMD electret mics offer better natural acoustic performance and lower cost for many applications.

If you need a compact, robust, and cost-effective mic solution for SMT production, SMD electret microphones are a strong alternative to both traditional and MEMS types.
