The choice of LED PCB mainly depends on several factors. Here are some of them:
Iref
The first factor business owners ought to consider is the LED type. Different LED applications require different PCBs. For instance, in commercial lighting, multilayer or standard PCBs are commonly used. At the same time, industrial and automotive lighting makes use of high-density or flexible LED PCBs. Also, the application of the PCB in question has a great impact on its design. This goes a long way in determining the specific requirements of the PCB.
Material Quality
LED PCBs are constructed using different materials. Each of these materials comes with its own benefits and drawbacks. While the main material used is FR-4, there are instances where aluminum is combined with other materials for added benefits. Therefore, business owners need to select PCBs made of materials that suit the needs of their customers. For instance, those looking for a durable and heat-resistant option are likely to benefit from aluminum PCBs.
Thermal Conductivity
Normally, this is one of the most important factors when selecting these PCBs. As highlighted earlier, these PCBs are commonly applied in areas with high thermal loads. This means that users should go for PCBs with high thermal conductivity. Ideally, it should be above 1.5 W/mk. Business owners should also ensure that the thermal resistance of the PCB is as minimal as possible.
Layer Count
These PCBs come in different layer counts. Each of these layers is suitable for different applications. Simply put, the higher the layer count, the more complex the circuit. So business owners should go for a higher count if their customers require PCBs for sophisticated applications. Retailers should also note that PCBs with a higher layer count are more expensive since they are more difficult to manufacture.
Circuit Thickness
Business owners should also consider the thickness of the circuit. Usually, thicker circuits lead to better conductivity. Further, this helps to reduce the chances of PCB warping. Consequently, shoppers should settle for thicker circuits if their customers intend to use high-powered LEDs. In general, a good PCB should have a film thickness of about 1.4mil.
There are several factors affecting the price of these PCBs. They include the number of layers, material thickness, and the complexity of the design. For instance, PCBs with more layers are likely to cost more since they are more complex to manufacture. Besides, the type of material used also affects the cost. Manufacturers who use high-quality FR-4 will sell their PCBs at a higher price than those who use standard material. Additionally, PCBs with a higher thickness value are more expensive. This is because they have greater durability and thermal conductivity. The surface finish and hole types also affect the cost of the PCB.
