Expanding the Horizons of Surface Mount Audio

As the demand for compact and efficient electronic components grows, PUI Audio continues to innovate with our latest lineup of surface mount audio and haptic devices. These new products, featuring enhanced durability and cutting-edge technology, are designed to meet the needs of modern electronics, whether in medical equipment, consumer devices, industrial applications, or specialized environments.

The Power of Surface Mount Technology

Surface Mount Technology (SMT) plays a critical role in the evolution of electronic manufacturing. By enabling components to be mounted directly onto the surface of PCBs, SMT allows for more compact and efficient assemblies, making it possible to integrate more functionality into smaller spaces. Our new offerings take full advantage of these benefits, ensuring reliable performance even in challenging environments.

New Surface Mount Speaker: SMS-2504MS-WP-HT

One of the standout products in our new lineup is the SMS-2504MS-WP-HT, a 25mm waterproof surface mount speaker. This speaker, with its slim 6.5mm profile, is designed to deliver powerful audio in a compact form factor. Capable of handling up to 2.5W of power and providing a 90 dB SPL across a broad frequency range (650 Hz to 20,000 Hz), this speaker is ideal for applications where both space and sound quality are paramount.

Key features of the SMS-2504MS-WP-HT:

• Compact Design: At just 6.5mm tall, this speaker is perfect for space-constrained applications.
• High Performance: Delivers a powerful 90 dB SPL, ensuring clear audio output.
• Wide Operating Range: Operates efficiently across temperatures from -40°C to 105°C, making it suitable for various environments.

Expanding the Transducer Range: SMT-1720-T-HT

Our SMT-1720-T-HT is the latest addition to our surface mount transducer range. This 17mm electromagnetic transducer is designed to operate at a resonant frequency of 2KHz, providing a high sound pressure level of 95 dB. Its broad temperature range from -40°C to 105°C ensures reliability in both industrial and consumer applications, from medical devices to communication systems.

Key features of the SMT-1720-T-HT:

• High SPL: Produces a sound pressure level of at least 95 dB at 10cm.
• Temperature Resilience: Operates effectively across extreme temperatures.
• Versatility: Suitable for a wide range of applications, from industrial to consumer electronics.

Reflow Best practices

Reflow soldering involves carefully controlling the temperature profile to ensure proper melting and solidification of solder paste, forming reliable solder joints for surface-mount components. The reflow process typically includes several distinct phases, each with specific temperature ranges and timing requirements. A typical reflow soldering profile for lead-free solder paste can be adjusted based on specific paste and component requirements, please reference individual specification sheets of the product for reference.

Reflow Soldering Profile

Ramp – This phase should be gradual to allow for uniform heating across the PCB, reducing the risk of warping or thermal stress.
Soak-The soak phase helps to prepare the solder paste for reflow by heating it to a temperature where the flux activates and begins to degas, which helps in reducing solder defects.

Peak – The peak temperature should be sufficient to fully melt the solder paste without overheating the components. The solder should form a smooth, reliable joint as it cools.

Cool – The cooling phase should be controlled to prevent rapid temperature changes that can cause solder joint defects or component damage.
