Why does flex have a thin layer of plastic on outside
The thin layer of plastic in flex is a protective coating that helps to prevent the flex from creasing or bending too much, which can damage the electrical components inside. It also helps to provide a smooth surface for the electrical traces to adhere to, ensuring a reliable connection and preventing shorts.

The thin, solid, outermost layer of the Earth is officially known as the crust.
All water starts to turn to ice at 0 degrees Celsius or 32 degrees Fahrenheit. it just depends how long you leave it to freeze. it usually takes about half an hour for a very thin layer of ice to appear on the top however it doesnt just freeze at the top, it freezes on the whole outside of the water so even if the top is a thin layer of ice after about an hour, there is a high chance that it is also frozen the whole of the outside to form like an ice container however the ice is very weak and even slightly touching it will cause it to break. hope this helps :)

A flex, or flexible printed circuit board (FPCB), often has a thin layer of plastic on the outside to provide insulation and protection. This layer helps prevent electrical short circuits, guards against moisture and contaminants, and enhances durability. Additionally, the plastic can contribute to the flexibility and lightweight nature of the circuit, making it suitable for applications in tight spaces or dynamic environments.
