The **WJFT5-ABB-R** is a specific electronic component, typically categorized as a **Board-to-Board (B2B) or Mezzanine Connector**. These parts are essential in modern electronics for linking two printed circuit boards (PCBs) together in a parallel or perpendicular configuration without the use of cables. --- ### 1. General Specifications While specific datasheets can vary by manufacturer (often associated with brands like Foxconn or JAE), the part number breakdown generally implies the following characteristics: | Feature | Description | | :--- | :--- | | **Component Type** | Board-to-Board Connector | | **Pitch** | Typically 0.5mm or 0.8mm (high-density) | | **Mounting Type** | Surface Mount (SMT) | | **Gender** | Often refers to the Receptacle (Female) or Plug (Male) | | **Plating** | Gold Flash or Gold over Nickel for high conductivity | --- ### 2. Key Electronic Features The WJFT5 series focuses on high-speed data transmission and physical durability. * **High Pin Count:** These connectors are designed to handle multiple signals simultaneously, often ranging from 20 to over 100 pins. * **Low Profile:** Designed for "thin" electronics (like laptops or tablets) where vertical space between boards is limited. * **EMI Shielding:** Many versions include metal tabs or shielding to prevent electromagnetic interference between the high-speed signals. * **High-Speed Signal Integrity:** Optimized for protocols such as PCIe, USB 3.0, or SATA. --- ### 3. Structural Design (The "ABB-R" suffix) In the world of electronic components, suffixes provide specific mechanical details: 1. **Alignment Bosses:** The "B" often indicates the presence of plastic "bosses" on the bottom of the part to ensure it sits perfectly straight on the PCB during the soldering process. 2. **Tape and Reel (R):** The "R" usually stands for "Tape and Reel" packaging, which is required for automated SMT (Surface Mount Technology) assembly lines. 3. **Lead-Free/RoHS:** These parts are manufactured to be compliant with environmental standards, using lead-free soldering materials. --- ### 4. Common Applications * **Mobile Devices:** Connecting the main logic board to sub-boards (charging ports, daughtercards). * **Computing:** Used in servers and laptops for expansion modules. * **Industrial Automation:** Linking control boards to interface boards.
