Easy to Manufacture & Integrate
The manufacturing of technology is never easy.
With a multitude of components, arrays, and so on, your average piece of technology has a lot going on in the background before it reaches the end-user.
While this is something that will never go away, what is clear is that the manufacturing process of LED PCBs is fairly simple and easy.
The end result of this is that the manufacturing process is simpler, while at the same time adding up to cost savings for the manufacturer.
