There are two main types of PCBs: rigid and flexible. Both have their own unique advantages and disadvantages, which is why it’s important to understand the difference between them before you make a purchase.
Rigid PCBs are made from a single layer of material, usually fiberglass or some other type of resin. They are very strong and can handle high voltages and temperatures, making them ideal for use in industrial applications. However, they are not very flexible and cannot be curved or bent.
Flexible PCBs, on the other hand, are made from multiple layers of material that are laminated together. This makes them very flexible and allows them to be curved or bent without breaking. They are also much less prone to failure than rigid PCBs, making them ideal for use in high-stress applications.
