What cushioning method is typically used for sensitive electronics shipped in racks or transport cases?

The use of suspension or shock mounts is particularly effective for sensitive electronics shipped in racks or transport cases because this method is designed to minimize the impact of shocks and vibrations during transit. By creating a buffer or suspension system for the electronic components, shock mounts help absorb and dissipate energy that could potentially damage delicate equipment.

These mounts typically consist of rubber or other elastomeric materials that act as dampers, allowing the electronics to be securely held while also being isolated from the jolts and bumps that may occur during handling and transport. This is crucial for preserving the integrity and functionality of sensitive electronics, which can be adversely affected by movement and impact.

While other methods, such as foam-in-place and bubble wrap, provide cushioning, they may not offer the same level of isolation from shock and vibration as suspension mounts, making them less suitable for critical electronic components that are especially sensitive to such conditions.
