Avoid Surprise In-Use Product Failures

Four Steps for Avoiding Surprise In-Use Product Failures

As we witness the birth of an era of connected devices with smart homes, connected cars and smart networked supply chains and factories, we might imagine that unexpected failures of electronic products would be a rarity. But all too often we hear about cellphones going up in flames, airbags that deploy on their own, or drones falling out of the sky.

The original design was a simple board with a wire bond package and several peripherals. Competitive pressures required a significant reduction in size and thickness.
