The **RG1-107S-R15** is a high-speed, board-to-board mezzanine connector typically manufactured by hardware interface specialists (such as Foxconn or similar industrial suppliers). It is designed to facilitate the connection between a main logic board and a secondary riser or daughter card. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Contact Density** | 107 Pins (Specialized configuration) | | **Pitch** | Typically 0.5mm or 0.8mm (depending on specific series variant) | | **Mounting Type** | Surface Mount (SMT) | | **Orientation** | Straight / Vertical | | **Plating** | Gold over Nickel (standard for signal integrity) | | **Application** | Networking, Server, and Industrial Computing | --- ### 2. Component Breakdown #### A. Contact Material and Plating The pins are generally made of a **copper alloy**. The "R15" suffix often refers to the thickness of the gold plating (e.g., 15 micro-inches), which ensures low contact resistance and prevents oxidation over long periods of operation in high-heat environments. #### B. Housing The body is made of high-temperature thermoplastic (UL 94V-0 rated). This allows the part to withstand the **Reflow Soldering** process without warping or melting. #### C. Signal Integrity The "RG" series is engineered for high-speed differential signaling. It includes features to minimize: * **Crosstalk:** Interference between adjacent signal pins. * **Impedance Mismatch:** Ensuring the 100-ohm (typical) differential impedance is maintained through the connector. --- ### 3. Common Use Cases * **Network Switches:** Connecting the main processing board to high-speed I/O modules. * **Server Racks:** Used in riser cards for PCIe expansion. * **Embedded Systems:** Connecting COM (Computer-on-Module) carrier boards. --- ### 4. Mounting & Footprint (Example Code) When designing a PCB for this part, the footprint must be precise. Below is a conceptual representation of how a designer might define a simplified SMT pad in a CAD script: ```python # Conceptual PCB Pad Definition for SMT Connector def generate_pad(x_pos, y_pos): pad_width = 0.3 # mm pad_height = 1.2 # mm return f"PAD at ({x_pos}, {y_pos}) size {pad_width}x{pad_height}" # Generate 107 pins (simplified logic) pads = [generate_pad(i * 0.5, 0) for i in range(107)] ``` ---
