An Aluminum Substrate for Suction Base Lamp PCBA is a specialized printed circuit board assembly designed for high-efficiency LED lighting systems, combining superior thermal management with electrical reliability. Built on an aluminum core (5052/6061 alloy) and dielectric insulation layer, it efficiently dissipates heat (1.0–3.0 W/m·K) to prolong LED lifespan and prevent overheating. With 1–3 oz copper traces, this substrate ensures stable current handling and supports high-power LED arrays while complying with UL 94V-0 and RoHS standards. Key applications include suction base lamps, commercial downlights, and architectural lighting, where its compact design, flame resistance, and **-40°C to +105°C** operating range make it ideal for residential and industrial environments. Manufacturers prioritize HASL/OSP finishes for solderability and corrosion resistance, ensuring durability in humid or high-temperature conditions.
