Sapphire Wafers

Just think what it would be like if we didn’t have to use 250 watts of electricity 24/7 for every single traffic light in the world. LED devices are now available to replace all these power grabbing, energy wasting lights. They use about 1/100th the power of conventional lights. Arrays of LEDs are being produced on sapphire substrates. PCA has developed a process of polishing these substrates about 9 times as easily as previous processes. We process substrates on our ultra flat polishers. We also reclaim sapphire substrates containing rejected production thin films. If you need flat polished sapphire substrates or reclaiming of your substrates, contact PCA.
