ZMSH Sapphire Substrate is a high-quality single-crystal product with superior surface quality. The product is made of C-plane or M-plane sapphire windows and has a thickness of 0.5-2mm. The warp of the sapphire wafer is less than 20μm and the parallelism is 3 arc seconds.
Sapphire substrate material is a kind of LED chip substrate material, sapphire stability is very good, can be used in the high temperature growth process; Finally, sapphire has high mechanical strength and is easy to handle and clean. Therefore, most processes generally use sapphire as a substrate
Sapphire Substrate Packaging and Shipping:
Each sapphire substrate is packed in an individual box and shipped in a bubble-wrap lined box.
The boxes are filled with foam to keep the sapphire substrates secure during transportation.
The packages are then sealed with tape and labeled with the product information.
The packages are then carefully loaded onto the shipping pallet and shipped to the customer.
