Random vibration assessment of a PCB
A consumer electronics client asked us to assess the reliability of a PCB in their latest product, focusing on its ability to withstand random vibrations during everyday use.
To tackle this challenge, we conducted a statistical analysis using the Power Spectral Density (PSD) method. This approach is ideal for non-deterministic loads, as it describes the vibration environment statistically rather than relying on exact values. By focusing on the long-term response and ignoring short transient effects, we could provide a clearer picture of the PCB's behavior under real-world conditions.
One key finding was that, with a 1 sigma output (68% probability), the PCB’s maximum displacement was predicted to stay within 0.01 mm. This insight reassured our client that their product met performance and durability standards, reducing the risk of vibration-induced failures.
If your product faces unpredictable loads, we’re here to help ensure it performs reliably, even in the most challenging environments.
