Electronic Component Validation with Accelerometers & Microphones

Today’s competitive electronics market requires advanced product validation, optimized designs, zero defects, and ever faster time to market. Supporting this, PCB Piezotronics provides Acoustic and Vibration sensors to many of the largest global consumer electronics manufacturers. New and customized sensors for Acoustics and Vibration are continually rolling out with ever smaller size and increasing levels of performance. New PCB® accelerometers continue to reach higher shock levels and new PCB® microphone models are being customized for sensitivity under unique application requirements.

Acoustic Measurement – PCB® has a wide breadth of test and measurement microphone systems for sound power, sound intensity, and sound pressure level measurements. PCB® microphone model 378A04 has been proved in audio & low noise validation applications. It is commonly used in development and end of line testing of portable devices, speakers, headphones, and earbuds under high amplitudes testing where less than 1% minimal Total Harmonic Distortion (THD) is required. There are more microphone and acoustic products to choose from including a 0V Prepolarized microphone and preamplifier system powered by ICP® 2-20 mA of constant current supply (interchangeable with accelerometer power and cable set-ups), externally polarized 200V systems, and 48V phantom powered systems for the Audio market. PCB® has the test and measurement system tailored for your application.

Shock & Fatigue - MIL &ISO testing standards provide a structured approach for testing to verify survivability under extreme operating conditions and to precipitate incipient failures so they are never experienced by an end-user. Shock tests subject assemblies to acceleration loads generated via measured drop or mass impact. Fatigue tests typically subject assemblies to specific vibration profiles with the goal of stressing mechanical components to failure. The addition of random vibration and thermal cycling takes testing to the next level in highly accelerated testing (HALT / HASS). Single axis models for shock reach measurement ranges to 20,000 g and triaxial models for fatigue reach 1,000 g, both with high frequency ranges.

When you need rapid data on product performance and survivability, rely on the PCB® product robustness you demand, unbeatable value, 24/7 support, best warranty, and fast shipment. If what you need is not listed in the PCB® Acoustics Catalog or R&D Brochure, please contact us for a customized solution.
