Printed circuit boards(PCB), are everywhere in our technology-based society. Everything from computers to medical equipment to cars contains these PCB in one form or another. However, not all PCB are the same— many of them use different designs or materials to suit a unique purpose. The base material is especially important for the circuit board, which helps determine how effectively the circuit board transfers heat.
Some applications require specific properties in their circuit boards. This is especially true for temperature-sensitive applications, one of which is LED lighting. The LED lighting industry is expanding rapidly in response to increased interest in the more efficient and cost-effective lighting method, but much of the functionality of LED lights depends on the temperature of its system. For many companies, the solution to this problem is in aluminum-based PCBs,We call it LED PCB.
To help you understand why the LED lighting industry uses Led PCB, we’ve outlined the nature of PCB base layers, the attractive qualities of aluminum PCBs and why they work well in the LED lighting industry.
LED PCB now widely used in more and more areas because of it’s Energy Saving and Environmental Protection.

If you have some inquiries with the LED PCB
Engineers design printed circuit boards to work best within their particular application. The designs can specify the nature of the circuit, the PCB coating material, the size of the PCB and a variety of other qualities. One of the most basic qualities to change, however, is the core of the circuit board.
PCB bases come in a variety of materials, including:
FR-4: Most common of these materials is FR-4, a base composed of glass and epoxy. While fire-retardant, FR-4 tends to be relatively inefficient at transferring heat.
Epoxies: Another, albeit less common substrate for PCBs is a material known as an epoxy. While less durable than other options, epoxy-based PCBs are much cheaper to manufacture.
Metal-core: Metal-core PCBs are very effective for a variety of applications, specifically those involving heat transfers. These bases consist of metal, usually aluminum, laminated with copper. These metals give the circuit board improved electrical insulation and thermal conductivity.
When thermal qualities are not as important, FR-4 or epoxy bases are more common, as these tend to be relatively less expensive. However, when thermal qualities are important for the proper function of the end product, metal-core printed circuit boards are likely the solution.
How to Make a LED Board or LED Circuit Board?
Making a LED (light emitting diode) circuit board is a good exercise for those new to electronics. It does not require a lot of components or expertise, and it is a useful circuit to know. When making a LED PCB, LED circuit board, you should be familiar with how a circuit board works. Columns of holes are electrically connected with exceptions for the first and last rows of holes. The first and last rows (rather than columns) of holes are electrically connected and are slightly offset from the main grid. This property of a circuit board makes the job of building a LED circuit board much simpler.
Things You'll Need
1" wire, 2 pieces
100 ohm resistor
Make a LED Board or LED Circuit Board Instructions
1.Wrap an end of your first wire around the positive terminal of your 9-volt battery.
2.Insert the other end of your first wire into the hole of your circuit board located in the first row and the first column.
3.Insert one end of your 100 ohm resistor into the same row as your wire,but this time in the second column of your circuit board.
4.Place the other end of your 100 ohm resistor in the hole of your circuit board located in the second row and second column.
5.Insert the anode (long wire) of your LED into the hole located in the third row, second column of your circuit board.
6.Insert the cathode (short wire) of your LED into the hole located in the third row, third column of your circuit board.
7.Wrap an end of your second wire around the negative terminal of your 9-volt battery.
8.Insert the other end of your second wire into the hole of your circuit board located in the fourth row, third column. You now have a completed LED circuit board and your light emitting diode will illuminate.
