### 2. Key Electronic Elements
#### A. Contact Design
The internal contacts are usually made of a **Copper Alloy**.
* **Conductivity:** High electrical conductivity to minimize signal loss.
* **Durability:** Designed for a specific number of mating cycles (usually 25–60 cycles).
* **Impedance Matching:** The geometry of the pins is engineered to maintain **50 or 100 Ohm differential impedance**, critical for PCIe Gen 3/4/5 signals.
#### B. Housing Materials
The body of the connector is composed of **High-Temperature Thermoplastic** (e.g., LCP - Liquid Crystal Polymer).
* **Reflow Compatibility:** Must withstand temperatures up to **260°C** during the lead-free soldering process.
* **Insulation Resistance:** Typically rated for >500 MΩ to prevent leakage between dense pin layouts.
#### C. Signal Integrity Features
* **Grounding Tabs:** The metal "shells" or "ears" on the sides (Solder Tabs) serve both as mechanical anchors and as a path to the PCB ground plane to reduce EMI (Electromagnetic Interference).
* **Keying:** The "R2/N" designation often refers to the **Keying configuration** (e.g., M-Key, B-Key, or E-Key), which determines which electronic signals (PCIe, SATA, USB) are allowed to pass through the interface.
