PET flexible PCB are a type of circuit boards with polyester film as the base material. They are widely used in various application scenarios such as touch screens, touch panels, and smart devices. PET have good transparency, flexibility, and heat resistance, and can adapt to curved and twisted working environments, so they are common in flexible electronic products.
Flexible circuits in electronic control systems
The rise in the popularity of electronic control systems can be more than any dispute put down to advancements in the field of electronics. When working with electronic systems, a large number of specific requirements have to be placed on the circuit boards: high durability, stability and environmental resistance all need to be optimized in terms of cost. Thus it is a necessity to use the best material for the flexible circuit board.
Most circuit boards made from PET are simple and inexpensive to produce. In the course of the realization of the touch technologies, it can be integrated with other components into one comprehensive touch display system.
Properties and benefits of PET flexible PCB
1. Heat and moisture resistant: Base material of PET are able to work in a temperate range of -40°C to 85°C centigrade with moisture tolerance, enabling them to be used for majority of the devices.
2. Moderate flexibility: The final temperature condition flexibility of PET’s substrate is adequate and can manage the assembled disposition of electronic components particularly where some bending is usual.
3. Light weight: Compared with rigid circuits, flexible circuit boards with PET as the substrate are lighter in weight, which will significantly reduce the weight of the final electronic equipment.
4. Thin thickness: The thickness of the flex printed circuit board based on PET is thinner, making electronic products more compact.
5. Low cost: Compared with PI film, PET film are more affordable, meeting performance requirements while reducing manufacturing costs.
The PET flexible PCB provided by Flex Plus has the following technical features:
Highly conductive copper foil layer: Using good quality copper foil as the conductive layer ensures that the circuit board has good conductivity during signal transmission, which helps to improve data transmission efficiency and response speed.
Tinned surface treatment: All copper circuit surfaces are tinned, which not only increases the corrosion resistance of the circuit board, but also improves its durability and service life.
