LED Strip Light PCB Quality: Double Side VS Single Side


led-strip-light-single-side-pcb-vs-double-side-pcbNow led strip light PCB have many kinds, double layer PCB, single layer PCB, rolled copper foil, plating copper. Best double layer PCB can bear large current, very good heat dissipation and has high stable quality.so we need to know What the is the difference between double layer PCB and single layer PCB of the led strip?

1. Flexible LED Strip PCB thickness

led-pcb-thinknessDouble-layer PCB and single layer PCB thickness mainly is cooper thickness.
the single layer PCB thickness is < 1-ounce thickness.
Best Double-layer PCB thickness is the 2-ounce copper thickness
In the market, there are also 1-ounce double layer PCB thickness

2. Hand Feeling

Without 3M Tape, you need to judge the led strip PCB quality by hand.
The double-layer PCB feel a little thick and hard and heavier than single layer led strip; it feels very good quality
The single-layer PCB feels thin, with no weight, very soft. it is easy to be blown by the wind.

3. Circuit at Backside

single layer PCB don’t have any circuit on the backside

4. the last point you may don’t know

important-noticeBest double layer PCB cover a layer of film on the front layer and backside. it feels hard and not very smooth. but in the market, some factories reduce the cost and price to make a film on the front side and a layer of oil at the backside. for single-layer PCB, it must cover a layer of oil. it touch very smoothly and have reflectors under the light, please see our second photo.
you must know, the PCB with a film is better than with the oil. it will be helpful for SMD led strip light to get very good heat dissipation and long working life.

From the guide, The above are basic experience to judge the led strip lighting quality. still, the higher quality it has, the higher price it is!
