Do you know the LED heart circuit manufacturing process?
To learn LED heart circuit manufacturing process,
First off you should know the construction of LED heart circuit.
In fact the construction of this type board has been some with normal LED circuit board, just the shape has been a heart.
A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil.
Do you know the LED heart circuit manufacturing process
The copper foil is etched into the desired circuit pattern.
If you have visit LED circuit board factory, you can image this process.
Or follow our series articles about LED heart circuit manufacturing process.
When the LED light working the metal base draws heat away from this circuit through the thin dielectric.
