DO NOT Use too Much Solder
When soldering your LED Strip Light it is important to not use too much solder and regularly clean your soldering iron. When your positive and negative solder joints touch one another this will cause an electrical arc that will eventually cause damage to your strip light.
DO Heat Shrink Over Connection
You should always use heat shrink over your finished solder joint to be sure that the joints are not exposed to any outside elements or especially when you are mounting your LED Strip to metal. It is not 100% necessary but definitely recommended.
DO NOT Leave Copper Pads Exposed
When you leave the copper pads on the bottom of your strip lights exposed and mounting them to any type of metal, your lights will not work because the copper pads will create an electrical arc and in turn most likely damage your strip lights over time.
