The **FF20-20A-R11A** is a specific type of Electronic Component, specifically a **Flat Flexible Connector (FFC/FPC)** manufactured by **DDK Ltd.** It is designed for high-density electronic packaging where space-saving and reliability are critical. --- ### ## Technical Specifications Below are the primary technical parameters for the FF20-20A-R11A: | Feature | Specification | | :--- | :--- | | **Connector Type** | FPC (Flexible Printed Circuit) Connector | | **Number of Positions** | 20 Pins | | **Pitch (Spacing)** | 0.5 mm | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Actuator Type** | ZIF (Zero Insertion Force) Slide Lock | | **Contact Location** | Bottom Contact | | **Current Rating** | 0.5A AC/DC | | **Voltage Rating** | 50V AC/DC | | **Operating Temperature** | -40°C to +85°C | --- ### ### Key Electronic Characteristics 1. **ZIF Mechanism:** The "Zero Insertion Force" mechanism allows the flexible cable to be inserted without friction. The slide lock (actuator) is then pushed down to secure the cable and create a high-pressure electrical connection. 2. **Bottom Contact Configuration:** This specific model is a **Bottom Contact** type. This means the conductive pads on your flexible flat cable (FFC) must face **downward** toward the PCB to make an electrical connection with the internal terminals of the connector. 3. **Right Angle Orientation:** The cable enters the connector parallel to the PCB surface. This is ideal for slim devices like tablets, laptops, or handheld scanners where vertical space is limited. --- ### ### Common Applications This part is typically found in consumer electronics requiring thin profiles: * **LCD Displays:** Connecting the screen driver to the main logic board. * **Mobile Devices:** Internal connections for cameras, buttons, or batteries. * **Printers:** Data transmission to moving print heads. * **Automotive Infotainment:** Connecting touch panels to the dash unit. --- ### ### PCB Footprint & Soldering For PCB designers, the landing pattern requires precise 0.5mm pitch pads. ```c // Example Pad Dimensions (Standard 0.5mm Pitch) Pad_Width: 0.30mm Pad_Pitch: 0.50mm Solder_Paste: Recommended thickness 0.12mm ```
