Sumitomo Metal Mining Co., Ltd. announced that it has set up a 150mm (6-inch) diameter sapphire substrate production line in its wholly-owned subsidiary, Otsuka Electronics (Izo, Kagoshima Prefecture, Japan), and has begun mass production. The production capacity is 10,000 pieces/month.
In addition, Sumitomo Metal Mine has established a growth technology for sapphire single crystals weighing approximately 130kg, and plans to transfer to mass production in 2013. From the 130kg sapphire single crystal, three cylindrical ingots can be cut, and the 80kg single crystal can only be cut into two, so the production efficiency is expected to be improved.
It is understood that Sumitomo Metal Mine has set up a large-scale crystal growth furnace and added a substrate processing production line in Dakou Electronics since the beginning of 2012. Established a short-term growth technique for sapphire single crystals with a diameter of about 30 cm and a weight of about 80 kg, and built the world's largest mass production system in the field of large substrates.

A manual pulse generator (MPG) is a device normally associated with computer numerically controlled machinery or other devices involved in positioning. It usually consists of a rotating knob that generates electrical pulses that are sent to an equipment controller. The controller will then move the piece of equipment a predetermined distance for each pulse.
The CNC handheld controller MPG Pendant with x1, x10, x100 selectable. It is equipped with our popular machined MPG unit, 4,5,6 axis and scale selector, emergency stop and reset button.
