### 2. Electronic Components & Design
The M2AS1-6112-R2 consists of several critical sub-elements that ensure signal integrity:
* **Contact Material:** Usually a copper alloy with gold plating over nickel. This minimizes contact resistance and prevents oxidation over long periods.
* **Insulator Body:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer). This is necessary to withstand **reflow soldering** temperatures (up to 260°C).
* **Solder Pegs/Tabs:** Metal tabs located on the sides of the connector provide mechanical stability, ensuring the connector doesn't rip off the PCB when the M.2 card is inserted or removed.
* **Signal Integrity:** Designed to support **PCIe Gen 3 and Gen 4** speeds. The internal lead frames are spaced to minimize crosstalk and impedance mismatch (typically 100-ohm differential).
