Printed circuit board adopts FR 4 military grade A material sheet, about the tolerance of the sheet and the stability of some parameters, the A material is very strong, which benefits from the high price of other materials.
Meanwhile, parameters of the components are directly printed on the printed circuit board, so you can directly solder without referring to the circuit diagram, which is quite convenient.
And pad is enlarged and sprayed with tin, which is easy to solder, and the pad is not easy to fall off after repeated soldering.
Not prone to spontaneous bending, such LED light DIY kit's installation is simple, not require particularly complicated operations.
Impedance is more stable and reliable and such LED light DIY kit's quality is guaranteed, you can use it with confidence.
