Abstract
A glass substrate carrier has a base, a tray assembly, a transmission device and a non-contact brake assembly. The base is movable. The tray assembly has a tray slidably mounted on the base and holding a glass substrate. The transmission device is mounted between the base and the tray assembly and is capable of driving the tray to extend out or retract back to the base. The non-contact brake assembly has a first brake element mounted on the base and a second brake element mounted on the tray assembly and un-contacting the first brake element. The first and second brake elements attract each other with an attractive force to brake a movement of the tray of the tray assembly. The first and second brake elements do not rub against each other and no dust is generated to damage circuit on the glass substrate.
