PET membrane switch VS FPC membrane switch


PET membrane switches and FPC (Flexible Printed Circuit) membrane switches are two distinct types of membrane switches used in electronic applications. The main difference lies in their base material. PET membrane switches use a polyester film (PET) as the substrate, offering flexibility and durability. On the other hand, FPC membrane switches utilize a flexible printed circuit, typically made of materials like polyimide, providing enhanced flexibility and a thinner profile. FPC membrane switches are often preferred for applications where space and weight are critical factors, while PET membrane switches are chosen for their cost-effectiveness and durability in less demanding environments.

Detail Description

Customer Background:

DD washing is a one-stop company who specializing for producing washing machines.

ICON Electronics is a leading laptop manufacturer known for its high-performance devices. They were looking to enhance the user experience of their premium line of ultrabooks by incorporating an advanced backlit keyboard.

Customer Project Challenges:

The challenge for ICON Electronics was to create a backlit keyboard that not only provided uniform and adjustable lighting but also maintained the sleek and slim design of their ultrabooks. Traditional backlit keyboards often faced issues such as uneven illumination, increased thickness, and limited customization options.

Yu An Electronics Solution:

Yu An Electronics, a pioneer in LGF membrane switch technology, collaborated with ICON Electronics to address their challenges. They proposed the integration of LGF membrane switches into the laptop’s backlit keyboard. LGF technology utilizes a thin and flexible film with printed light guides, ensuring uniform light distribution across the entire keyboard. Yu An Electronics worked closely with ICON Electronics’ design and engineering teams to customize the LGF membrane switches according to the laptop’s form factor and design specifications. The LGF technology allowed for precise control over the backlighting, enabling adjustable brightness levels and dynamic lighting effects.To overcome the challenge of maintaining a slim profile, Yu An Electronics optimized the thickness of the LGF membrane switch, ensuring it seamlessly integrated into the laptop without compromising on aesthetics or performance.

Customer Satisfaction:

Upon the launch of the new ultrabook with the LGF membrane switch backlit keyboard, ICON Electronics experienced positive feedback from both users and industry experts. The backlit keyboard not only met but exceeded customer expectations, providing a premium and seamless typing experience with uniform backlighting. Users praised the keyboard’s aesthetics, the ability to customize lighting effects, and the overall improvement in typing comfort. In the following days, Yu An Electronics got bulk orders from ICON, and established the stable business relationship until now.
