Contoured shapes, asymmetrical workspace, and no place to mount can make things a little tricky to use a rigid circuit board. Flex OR flexible circuits are the right choices in such a scenario. The blog is your primary guide to how things work with a flex circuit and the potential advantages of using one. Likewise, things that bend are harder to break and may last a bit longer in pressure situations. A flex circuit would be made of conductive metal pieces, preferably of copper and coated with a protective layer called the solder mask—this where things become different from the rigid and flex circuit. The flex circuit gets its polyimide coat to ensure superior flexibility. This material is an excellent insulator for heat and helps the board to bend without breaking.
What Makes A Flex Circuit a Primary Choice?
In simple words, it is the plastic part that makes these boards a great option. Now moving on with specifics:
- Additional components can be omitted, and extra connectors can be neglected.
- Fits comfortably into limited/smaller spaces.
- Works best with different places and machinery that has a higher vibration rate that can destroy a rigid and fixed circuit board.
- Practically flexible and can move with machines that operate using mechanical arms and other movable parts.
- You can easily use flex circuits to cut down the costs of labor and manufacturing. No other connections and simplified installation make them a great option in spaces where just a single board can be fitted by squeezing it.
- Lighter, this flex circuit has a lesser board to it than a conventional PCB. This is where the board provides a substantial reduction on the weight side. This helps it becomes a probable choice for smaller gadgets where weight reduction is the key.
- Better heat resistance can be achieved with the polyimide used as an insulator on the flex circuit. This is what makes them an excellent option for frequently moving and excessively vibrating machines.
- Savings come in all forms, cost savings come with about 30% of the extra wires eliminated, and space-saving up to 60% with additional flexibility.
- The savings in resistance to heat and many other aspects help the flex circuits prove themselves as a practical option and display higher reliability.
While the conventional rigid PCB is still in use and has always not be replaced in the entirety, flex circuits have started to make some noise amongst the electronic item manufacturing industry. With a rise in need for compact gadgets and products, flex circuits have become a priority for many and may soon be the future of PCBs.
