Flex PCBs Perform in High-Altitude Environments
Printed circuit boards that are designed to be flexible can offer several benefits. For example, they can allow a device to bend and twist without experiencing any breakage or failure. They can also be routed at tough angles within a tight space, which helps to reduce overall device weight while still allowing for high conductor density. In addition, flex PCBs can resist vibrations and other disruptions in harsh environments.
However, when it comes to high-altitude environments, there are some special considerations for flex pcbs. These can include the operating environment, the operating temperature range and the maximum amount of bending that will occur. It’s also important to consider the thickness and materials used to manufacture the flex PCB. This will help to ensure that the board can handle the stresses that it will be subjected to in high-altitude environments.
The most common flex circuits are single-sided, double-sided, and multi-layer. They can be constructed with various conductor layers, adhesives, laminates and polyimide materials. In general, the higher the layer count, the more rigid the flex circuit will be and the less it will flex.

It’s important to consider the operating environment and the maximum amount of bending that will be required of the flex circuit before determining the appropriate type and thickness of material. The thickness of the copper plating and the layer configuration will also have an impact on how much flexing is possible. In general, it’s best to use thinner copper traces because they will be less likely to crack during bending.
A flex circuit can be reinforced to increase its ability to withstand stress by using pad fillets, which are thin metal strips placed around the edges of pads on the flex circuit. This will prevent the pads from tearing or cracking during flexing and other processes such as soldering. In addition, pad fillets can improve the etch yield and material strength of the flex circuit.
Another way to make a flex circuit more resistant to bending is to use wider ends on the traces. This will also improve the mechanical performance of the flex circuit. It is important to remember that the wider end will need to be exposed for components and connectors to connect to it.
A specialized type of flex circuit called a back-bared flex is also available. This allows access to selected features of the conductor pattern on both sides of the flex circuit. This is important in certain situations because it can reduce manufacturing costs and improve reliability by reducing the need for plated-through holes.
