The designation **"006-R"** is most commonly associated with **ZIF (Zero Insertion Force) Test Sockets** and certain high-precision connectors, specifically from manufacturers like **Yamaichi Electronics**. --- ### 1. Primary Identification: Yamaichi IC Test Socket In the electronics industry, "006-R" is frequently a suffix or part of a series for IC testing sockets used during the programming and burn-in phases of semiconductor manufacturing. #### Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | ZIF (Zero Insertion Force) Socket | | **Common Series** | IC51 Series (e.g., IC51-0804-006-R) | | **Body Material** | PEI (Polyetherimide) or PPS (Polyphenylene Sulfide) | | **Contact Material** | Beryllium Copper (BeCu) with Gold over Nickel plating | | **Operating Temp** | -40°C to +150°C (standard range) | --- ### 2. Key Components & Mechanics The "006-R" variant usually indicates a specific pin configuration or a "RoHS compliant" version of a legacy part. * **Clamshell Actuator:** The top of the part usually features a hinged lid. Closing the lid applies uniform pressure to the IC leads without requiring the user to push the chip into a tight friction fit. * **Contact Type:** Usually features "Y-shape" or "Pinch" contacts that grip the sides of the IC pins to prevent lead deformation. * **Pitch:** Often associated with 0.5mm, 0.65mm, or 1.27mm lead pitches depending on the specific chip package (QFP, SOP, or BGA). --- ### 3. Alternative Use Case: Power Inductors In some contexts, "006-R" can refer to a specific resistance value in power inductors or resistors (where "R" acts as a decimal point). * **Value:** 0.006 Ohms (6mΩ). * **Application:** Current sensing or high-efficiency filtering in power supplies. --- ### 4. Common Packages Supported Parts ending in this nomenclature are typically designed for: 1. **TQFP/LQFP:** Thin Quad Flat Packages. 2. **SOP/TSOP:** Small Outline Packages. 3. **Burn-in Boards:** Used by engineers to stress-test chips at high temperatures before final assembly. ---
