>>>What is difference between double sided PCB and single sided PCB of led strip?

Why does the led strip price has such big differece?
What to look for when you purchase led strip for your unqiue needs?
How to avoid the mistakes when you buy led strips?

LED Strip PCB is also the key to high quality but LED. Best double sided PCB can bear large current, very good heat dissipation and has high stable quality.

Here are our experience and basic led strip knowledge sharing with you.

1. Flexible LED Strip  PCB Thickness

Double sided PCB and single sided pcb thickness mainly is cooper thickness.

single sided PCB thickness is < 1 ounce thickness.
Best Double sided PCB thickness is 2 ounce cooper thickness
In the market, there are also 1 ounce double sided pcb thickness

2. Hand Feeling

Without 3M Tape, you needs to judge the led strip pcb quality by hands.

The double sided PCB feel a little thick and hard and heavier than single sided led strip; it feel very good quality

The single sided PCB feel thin, no weight, very soft. it is easy to be blown by wind

3. Circuit at  Backside

double sided PCB of high quality led strip must have circuit on front sided and backside;
single sided pcb don’t have any circuit on the backside

4. the last point you may didn’t know

Best double sided PCB cover a a layer of film on the front sided and backside. it feels hard and not very smooth. but in the market, some factories reduce the cost and price to make a film at the front side and an layer of oil at the backside.

for single sided pcb, it must covers an layer of oil. it touchs very smooth 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 guideness, The above are basic experience to judge the led strip lighting quality. still, higher quality it has, higher price it is!
