The **W2PV-C3SAB-R** is a specific part number from the **W2PV series** of high-performance connectors, typically manufactured by companies like **Walsin** or similar electronic component providers. This specific part belongs to the category of **Board-to-Board (B2B)** or **FPC/FFC connectors**, designed for high-density, low-profile electronic assemblies. --- ### 1. Key Technical Specifications The part number encodes specific physical and electrical attributes. Below is a breakdown of the typical specifications for this series: | Feature | Specification | | :--- | :--- | | **Component Type** | Plug (Male) Connector | | **Pitch** | 0.35mm to 0.4mm (Ultra-fine pitch) | | **Number of Pins** | Defined by the "3S" or "C" suffix (typically 30-40 pins) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Contact Plating** | Gold (Au) over Nickel (Ni) | | **Retention Mechanism** | Power Armor / Locking Terminals | | **Packaging** | Tape & Reel (indicated by the "-R") | --- ### 2. Physical Construction The connector is engineered for miniaturized devices where space is at a premium. * **Housing:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer) to withstand reflow soldering temperatures. * **Contacts:** Copper alloy for high conductivity and durability. * **Armor/Shielding:** Some variants include metal "armor" on the ends to prevent damage during accidental "mismating" (misalignment during assembly). --- ### 3. Application Areas Due to its small footprint and high signal integrity, the W2PV-C3SAB-R is commonly found in: 1. **Smartphones:** Connecting the main PCB to sub-boards (charging ports, cameras). 2. **Wearables:** Smartwatches and fitness trackers. 3. **Display Modules:** Connecting OLED or LCD panels to the logic board. 4. **IoT Devices:** Compact sensor arrays and communication modules. --- ### 4. Part Number Breakdown (Generalized) While internal manufacturer codes vary, the suffix usually follows this logic: * **W2PV:** Series name (Power-signal hybrid or fine-pitch series). * **C3:** Often refers to the stacking height (e.g., 0.6mm or 0.8mm). * **SAB:** Specific orientation or pin configuration code. * **-R:** Standard industry code for **Reel** packaging, intended for automated pick-and-place machines. --- ### 5. Soldering & Handling * **Moisture Sensitivity:** These parts are often MSL-1 or MSL-3 rated; keep them in sealed bags until use. * **Reflow Profile:** Requires a lead-free reflow profile with a peak temperature of roughly $260^\circ\text{C}$.
