A transit case uses isolating mounts to protect electronic payloads from vibration. These mounts are chosen with a natural frequency of vibration significantly different from the expected excitation frequency. This helps ensure the minimum of vibration is transmitted to the payload. However, there are challenges: Continue reading →

Vibration is bad for electronic devices such as radio transmitters and computers. Screws can work loose and cards and cables can come unplugged. As a result, equipment is sometimes inoperable after a long journey. Fortunately, that kind of damage is usually easily repaired, unlike the harm caused by resonance. Continue reading →

There are several exceptional benefits of aluminum cases, including protecting sensitive equipment during transportation. Fragile contents need protection from vibration and shock, and aluminum cases are great for dampening impacts and oscillations. Continue reading →

In my last two postings I reviewed equipment fragility and the influence of handling and transport on packaging design. The most common approach to protecting equipment within a carrying case, transit case or shipping case is to use foam cushioning. In this posting, I’ll provide an overview of foam materials.

Boats, trucks, trains and planes can be bad for electronic equipment. The constant vibration is the problem. Vibration damages boards and components, which causes premature failure. It’s why mission-critical equipment should be protected in a high-quality transit case engineered to absorb the shaking. Continue reading →
