Custom 20W LED Module PCBA: 300×20×2mm Aluminum Board with 60pcs Samsung 561C LEDs (26-36V, 2.0W/m.k)
Product Description
Overview
The 20W Linear LED Module PCBA is a high-efficacy, heavy-duty light engine engineered for high-performance commercial and linear architectural luminaires. Measuring 300mm × 20mm × 2mm, this rigid aluminum board incorporates 60 pieces of premium Samsung 561C LEDs arranged in a 10-series / 6-parallel (10S6P) circuit layout. Operating on a 26–36V DC constant current (300mA) supply, it features a heavy 2oz copper foil and 2.0 W/m·K thermal dielectric layer for optimal heat dissipation and ultra-low thermal resistance. Equipped with 4 single-pin push-in connectors, it ensures solderless, rapid wire interconnection for OEM/ODM fixture manufacturers.

Q&A:
Q1: What LED driver specifications are required for this 30W linear PCBA board?
A: This module requires a constant current LED driver delivering 300mA with an output voltage window covering DC 26V to 36V (approx. 30W output per board).
Q2: How do the 4 single-pin connectors work on this 300×20mm module?
A: The board includes 4 surface-mounted single-pin push-in terminals (typically 2 for positive/negative input and 2 for pass-through daisy-chaining). They accept solid or tinned stranded wires without manual soldering, significantly reducing labor time during luminaire assembly.
Q3: Can this 300x20mm PCB layout be customized for different dimensions or LED brands?
A: Yes. As a custom LED PCB & PCBA manufacturer, we can adjust the aluminum board dimensions, change connector locations, modify circuit series/parallel ratios, or substitute LEDs with other brands (e.g., Cree, Lumileds, Bridgelux, Sanan) based on your OEM requirements.
