Abstract
In order to reduce cycle times for assembling at least two substrates () in order to form an optical data carrier in a low-pressure chamber (), a method and a device are disclosed wherein an opening () of the low-pressure chamber is sealed in relation to the surrounding environment, the low-pressure chamber is pumped out, a transfer chamber () is formed between a first handling device () arranged in the low-pressure chamber and a second handling device () arranged outside the low-pressure chamber by respectively sealing the opening () of the low-pressure chamber (). The transfer chamber () has a smaller volume than that of the low-pressure chamber (); the substrates () in the transfer chamber () are transferred from the second handling device () to the first handling device (); the substrates are conveyed () with the first handling device () to an assembly station () in the low-pressure chamber when low-pressure chamber is sealed by the second handling device (), and the substrates () are assembled in the assembly station ().
