FPC Mobile for Slim & High-Performance Smartphones

Introduction: Mobile devices use Flexible Printed Circuits (FPCs). They are slim, lightweight, and high-performing.

FPCs are better than rigid PCBs. They let you easily integrate key parts and stay flexible.

In smartphones, the main FPC links key parts. This includes the motherboard, display, battery, and cameras. This ensures smooth communication between them.

2. Mobile FPC Connectors: Ensuring Secure & Stable Connections

To ensure the stability and flexibility of the contact, FPC requires specialized connectors to achieve it. In current applications, there are mainly two types, which are:

BTB (Board-to-Board) Connectors

Compact connectors link PCBs. They have high-density pins, like a 0.35mm pitch, and low-profile designs, with a height of 0.6mm or less. Great for small devices like smartphones. It offers stable connections but has a limited number of mating cycles.

ZIF (Zero Insertion Force) Connectors

Designed for flexible circuits (FPC/FFC), this enables easy, tool-free insertion and removal. It also features a locking mechanism. Common in display cables, supports frequent maintenance but requires a larger space‌

3. Applications: Where Are They Used?

Perhaps you have a curious question: What are the uses of FPC in mobile phones?

They are widely used in:

Smartphone displays – Enabling ultra-thin touchscreens
Camera modules & fingerprint sensors – Supporting precise image and biometric data
