FPC Connector	Very flexible; custom patterns; low profile	Used in sensors and screens
FFC Connector	Less flexible; only bends a little	Not used much in wearables
BTB Connector	Stiff; not for bending cables	Used for strong connections

Battery FPC connectors use copper clad foil that is flexible. This lets them bend and fold without breaking. The connector moves with your device.

Compactness

Wearables should be small and light. Battery FPC connectors use a single-row terminal. This design makes the mounting area almost half as big. Your device gets smaller and easier to carry. The connector can handle strong shakes and bumps. This keeps your wearable working well. It can carry large currents, so charging is fast. The connector does not need to be bigger for this. Power and signal terminals are in one small piece. This gives you more features in less space.

Copper traces on flexible bases are important. These traces carry power and signals. They use thick copper layers to support high current. The flexible base, often made from polyimide, bends to fit small spaces. Polyimide stands up to heat and chemicals. This keeps your device safe and strong. Sometimes, polyester is used to save money. But polyimide is better for wearables.

ZIF and Locking Mechanisms

You want your device to last a long time. ZIF connectors let you put in cables with almost no force. This keeps the inside parts safe. Locks like flip-locks or slider-locks hold the cable tight after you put it in. You do not have to worry about the cable coming loose. Other locks, like autolock or pull-out locks, add more safety.

ZIF connectors and locks make it easy to put together your device. They also protect it from damage. You get a strong connection that lasts through many bends and moves.

These features help your wearable stay safe and comfy. The connector takes in shakes and does not wear out fast. You can use your device every day without problems.

Role in Wearable Devices

Miniaturization

People want wearables to be small and light. Battery FPC connectors help make this happen. They use very tiny pitch sizes, like 0.21 mm or 0.3 mm. This lets many connections fit in a small space. The connectors are thin, sometimes only 0.5 mm tall. This helps make devices less thick. The cables are also very thin, about 0.18 mm to 0.20 mm. This keeps the device light. Special locks, like autolock and flip lock, hold parts tight. These locks work well even in small spaces.

• Tiny pitch sizes let more connections fit
• Thin connectors make devices less thick
• Ultra-thin cables keep things light
