The **W2VS-162A-R2** is a specialized high-speed electronic connector, typically part of a vertical stacking or mezzanine system used in telecommunications, servers, and high-end industrial computing. It is designed to facilitate high-density board-to-board connections. ### 1. General Specifications The following table outlines the technical characteristics of the W2VS-162A-R2: | Feature | Specification | | :--- | :--- | | **Contact Quantity** | 162 Pins | | **Connector Type** | Board-to-Board (Plug/Receptacle) | | **Orientation** | Vertical (Straight) | | **Mounting Type** | Surface Mount (SMT) | | **Pitch** | Typically 0.5mm or 0.8mm (Model dependent) | | **Plating** | Gold (Au) on contact area for high conductivity | --- ### 2. Key Electronic Components & Materials The connector is composed of several critical layers and parts that ensure signal integrity: * **Housing (Insulator):** Made of High-Temperature Thermoplastic (LCP - Liquid Crystal Polymer). This allows the part to withstand lead-free reflow soldering temperatures. * **Contact Pins:** Phosphor Bronze or Copper Alloy. These materials are chosen for their balance between electrical conductivity and mechanical elasticity. * **Solder Tabs:** Located at the ends of the connector to provide mechanical strain relief to the PCB, ensuring the Solder Joints do not crack under vibration. * **Shielding:** Some versions of the R2 series include integrated metallic shielding to minimize Electromagnetic Interference (EMI) in high-speed data transmission. --- ### 3. Application Use Cases Because of the high pin count (162) and compact footprint, this part is commonly found in: 1. **Network Switches:** Connecting main logic boards to daughter cards. 2. **Medical Imaging:** High-speed data transfer between sensor arrays and processing units. 3. **Industrial Automation:** Modular PLC systems where space is at a premium. --- ### 4. Integration Example (Footprint Reference) When designing a PCB for this part, the CAD software usually defines the landing pattern as follows: ```markdown # Footprint Recommendation - Pad Width: 0.25mm - 0.30mm - Pad Length: 1.20mm (varies by land pattern) - Solder Paste Stencil Thickness: 0.12mm - Keep-out Zone: 2mm perimeter for automated pick-and-place nozzle clearance. ```
