The **FTG-14-R** is a specific type of electronic component typically categorized as a **Fine-Pitch, Board-to-Board (BtB) or Board-to-FPC Connector**. These components are essential in modern compact electronics like smartphones, tablets, and wearables where space is at a premium. --- ### 1. Key Technical Specifications The "14" in the part number generally refers to the **pin count** (14 positions), while the "R" often signifies the packaging type (Reel) or a specific orientation. | Feature | Description | | :--- | :--- | | **Component Type** | Board-to-Board / Board-to-FPC Connector | | **Pin Count** | 14 Pins | | **Pitch** | Typically 0.35mm to 0.5mm (Ultra-fine pitch) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Mated Height** | Low profile (usually 0.6mm to 1.0mm) | | **Contact Material** | Copper Alloy with Gold Plating (for conductivity and anti-corrosion) | --- ### 2. Functional Electronic Parts The FTG-14-R is comprised of several critical sub-elements that define its electrical performance: #### A. Contact Terminals * **Material:** Phosphor bronze or copper alloy. * **Plating:** Gold plating is used on the contact points to ensure low contact resistance and to prevent oxidation over time. * **Function:** They provide the electrical path between the motherboard and the peripheral (like a camera module or screen). #### B. Insulator Body (Housing) * **Material:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). * **Function:** It holds the pins in precise alignment and prevents short circuits between adjacent pins. It must withstand the high heat of lead-free reflow soldering. #### C. Solder Tabs (Nails) * **Function:** Located at the ends of the connector, these metal tabs are soldered to the PCB to provide mechanical strain relief, ensuring the connector doesn't pull off the board during plugging/unplugging. --- ### 3. Application Examples Because of its small footprint and 14-pin configuration, this part is commonly used for: * **Camera Modules:** Connecting a small CMOS sensor to the main PCB. * **Display Links:** Connecting small LCD or OLED touch panels. * **Sensor Arrays:** Linking fingerprint scanners or proximity sensors. * **Battery Connections:** In devices where the battery uses a flex cable instead of wires. --- ### 4. Handling and Soldering Due to the microscopic nature of the pins, specific precautions must be taken: ```yaml Soldering_Method: Reflow Soldering only Stencil_Thickness: 0.08mm - 0.10mm (recommended) Inspection: Automated Optical Inspection (AOI) or X-Ray required ```
