LED PCB Board

What Is Led PCB Board ?

Led PCB board is the core of the led lighting. A chip creates an electrical connection between LED and printed circuit board, and there has a thermal heat sink to dissipate heat. Because of the well-performance in dissipate heat, the metal core PCBs, especially aluminum PCBs are popular for led PCB board manufacturers. Usually, the aluminum led PCB board has a thin layer of thermally conductive dielectric material that is more efficient at dissipating heat than traditional PCBs.

Advantages of Led PCB board:

  • Well performance for heat dissipating
  • Lightweight
  • Efficient low power consumption
  • Dust and moisture resistant
  • Mercury-free
  • Radiofrequency-free:

LED PCBs Board Design Guide

The led PCB manufacturing process is becoming increasingly popular. It has widely applications in our daily life from computer to automotive industry. This kind of printed circuit board integrates the LEDs(Light Emitting Diodes) onto PCBs (Printed Circuit Board). Aluminium is the idea material for Led circuit board fabrication because of its great heat dissipation, and the high efficiency, low cost, and structural strength make the Led light circuit board become popular for manufacturing industry.

In the led PCB manufacturing process, there are some considerations for high-quality LED PCB fabrication:

1.Create the ideal board design layout

Create the ideal board design layout is the primary step for Led PCB board design, because it usually decides the cost and quality of the final PCBs. Specialized LED PCB designer will design professional Led light circuit board design for customers that can avoid the most defects.

2.Ensure the correct orientation

All the Led pcb boards have a orientation from one entry to one exit or most a few. The orientation is that the electricity and data flow. Might a printed circuit board has more than one orientations, so the professional Led PCB board design should ensure all the orientations is from begin to the end.

3.Consider the subject of component placement

Every Led pcb board has its specific use, therefore we should consider the subject that might be needed, such as capacitors, resistors, etc. Besides, LED PCB designers should also consider where to place these components, and avoid arranging them on the solder side of the printed circuit board.

4.Placing components away from the PCB outline

Placing components away from the PCB outline is crucial to help manage the LED PCB board design, and protect the printed circuit board from failing in the future. Besides, if you place the component near the PCB outline might cause theses components dislodge from the board.

5.Placing components according to SMD PCB design rules.

Placing components according to SMD PCB design rules is a good method to fabricate the high-quality LED PCBs and make it efficient, because the SMD PCB is a standard reference to a set of guidelines for PCB manufacturers to make high-quality products.

6.Placing VIAs away from the end of SMT pads.

The VIAs(vertical interconnect assess) allows manufacturers place components onto the printed circuit board between two or more layers. Placing VIAs away from the end of SMT pads is very important to avoid the PCB defect that the solder to migrate leave from the pad and enter the via space. Therefore, create the distance of 0.025 inches is great between the via and the SMT pad.

7.Net width design

We need to definite the net width for the variability of currents.

Types of Led PCB Board

Different types of Led circuit boards are created for different application, typically, there are 5 types of LED PCBs.

They are flexible Led circuit boards, rigid LED PCBs, hybrid LED PCBs, multi-layer LED PCBs, single-layer LED PCBs.

What Causes A PCB to Fail?

Led pcb manufacturing process defects

There are malfunction of Led PCB boards might caused manufacturing defects, such as low-quality solder joint connection, material degradation, and contamination. To solute these defects of led light pcb board, you should create the right pad-trace. This can ensure your material is high-quality, and keep clean on the led light pcb board surface.

The second reason why your Led PCB board fail is caused by environmental factors. They are heat, dust, moisture, and physical shock.

Non-specific design is also an important reason to make malfunction of your Led PCB board. You should consider in component selection, material selection, PCB layout, and design verification.

Some common Led PCB board core materials include the following.

FR-4: FR-4 consists of glass and epoxy resin and is one of the most common core materials for custom led pcb boards. It is flame retardant but is not particularly effective at transferring heat.

Epoxy resin: Epoxy resins are another common choice for custom led pcb boards. They are not as durable as other core materials but are less expensive to manufacture.

Metal Cores: Metal core PCBs are usually aluminum and other metals and laminated with copper. These materials can be used in heat transfer applications and provide excellent thermal conductivity and electrical insulation.

Because of the vital role of heat transfer in Led circuit board applications, metals, especially aluminum, are the most common Led light pcb board materials.

Aluminum PCB boards are the most common type of LED PCB boards.

These boards sit on an aluminum alloy base, typically composed of aluminum, magnesium, and silicon. Aluminum LED PCB boards are used in many applications, including flexible aluminum, hybrid aluminum, and multilayer aluminum.

Aluminum custom led pcb boards consist of multiple layers.

Base layer: The base layer consists of an aluminum alloy board

Thermal barrier: The thermal barrier of the aluminum LED PCB board consists of a ceramic polymer that protects the board from thermal and mechanical damage.

Circuit layer: This layer contains copper wires arranged according to the circuit design of the custom led pcb boards.

The custom led pcb boards has different numbers of these layers depending on the design of the custom led pcb boards.
