The **F2VF-40-R/Q** is a high-performance, high-density board-to-board connector, commonly manufactured by providers like **I-PEX** (specifically part of the MHF or similar micro-miniature series) or used in specialized high-frequency industrial designs. Below is a breakdown of its technical specifications and electronic properties. ### 1. General Specifications This part is categorized as a fine-pitch connector used for internal PCB connections in compact electronics. | Parameter | Value/Description | | :--- | :--- | | **Pitch** | 0.4 mm (High density) | | **Pin Count** | 40 Pins | | **Type** | Receptacle (Socket) | | **Orientation** | Vertical (Straight) | | **Mating Height** | Typically 0.7mm to 1.0mm (Ultra-low profile) | --- ### 2. Electrical Characteristics The electronic performance of the F2VF-40-R/Q is optimized for high-speed signal integrity and power delivery in small form factors. * **Current Rating:** Approximately 0.3A per pin (Signal) / Up to 1.0A for power-dedicated pins (depending on specific sub-series). * **Voltage Rating:** 50V AC/DC. * **Contact Resistance:** Max 40mΩ to 80mΩ (initial). * **Dielectric Withstanding Voltage:** 250V AC for 1 minute. * **Insulation Resistance:** 100MΩ minimum. --- ### 3. Physical & Material Composition The materials are chosen to ensure durability despite the microscopic scale of the pins. * **Housing:** LCP (Liquid Crystal Polymer), UL94V-0 rated, heat resistant for reflow soldering. * **Contact Material:** Copper Alloy (High conductivity). * **Plating:** Gold plating over Nickel (to prevent oxidation and ensure stable conductivity over multiple mating cycles). * **Solder Tabs:** Often includes metal "Hold-downs" or "Solder pegs" to increase the mechanical strength of the connector on the PCB. --- ### 4. Typical Applications Due to its 0.4mm pitch and 40-pin configuration, this part is found in: 1. **Mobile Devices:** Connecting displays (LCD/OLED) to the mainboard. 2. **Cameras:** Sensor-to-processor high-speed LVDS/MIPI links. 3. **Wearables:** Dense circuitry in smartwatches or AR/VR headsets. 4. **Medical Imaging:** Handheld ultrasound or diagnostic tools. --- ### 5. Soldering Footprint (Conceptual) When designing a PCB for this part, the landing pattern must be extremely precise. ```c // Example Layout Considerations - Pad Width: ~0.23mm - Pad Pitch: 0.40mm - Solder Paste Thickness: 0.10mm - 0.12mm (recommended) - Keep-out zone: Required around the mating area to avoid mechanical interference. ```
