The **WEPA-14PDD-R** is a specific electronic component, typically categorized as a **Board-to-Board (B2B)** or **FPC/FFC connector**. These parts are designed for high-density electronic assemblies, such as those found in consumer electronics, medical devices, or automotive displays. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the WEPA series, here are the primary electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | Board-to-Board / Mezzanine | | **Number of Positions** | 14 Pins | | **Pitch** | Typically 0.5mm or 0.8mm (depending on series) | | **Mounting Type** | Surface Mount (SMT) | | **Orientation** | Right Angle or Straight (usually denoted by 'R') | | **Plating** | Gold (Au) flash for high conductivity and oxidation resistance | | **Packaging** | Tape & Reel (TR) for automated assembly | --- ### 2. Physical Construction The part is comprised of three main material groups: * **Housing:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer). This allows the part to withstand **lead-free reflow soldering** temperatures (up to 260°C). * **Contacts:** Copper alloy (Phosphor Bronze). This provides the necessary spring force and electrical conductivity. * **Shell/Shielding:** Often includes a metal shell for EMI (Electromagnetic Interference) protection and mechanical robustness. --- ### 3. Circuit Application In a circuit, the WEPA-14PDD-R serves as the bridge between two Printed Circuit Boards (PCBs). 1. **Signal Integrity:** Designed for low-voltage differential signaling (LVDS) or standard GPIO signals. 2. **Current Rating:** Usually rated for **0.5A per pin**. It is not designed for high-power delivery but for data and low-power logic. 3. **Voltage Rating:** Typically rated for **50V AC/DC**. ### 4. Part Number Breakdown (Typical) | Segment | Meaning | | :--- | :--- | | **WEPA** | Series Identifier | | **14** | Pin Count (14 pins) | | **P** | Plug (Male side) | | **DD** | Design Revision / Dimension code | | **R** | Right Angle / Reel Packaging | --- ### 5. Common Use Cases * **Mobile Devices:** Connecting a camera module to the main logic board. * **Displays:** Interfacing a small LCD/OLED screen to a controller. * **IoT Sensors:** Modular sensor attachments where space is limited. ---
