Abstract:
A method for carrying out working steps on miniaturized modules held by at least one module carrier provided with a holding device for at least one of said modules, wherein in order to carry out at least one of the working steps on at least one of the modules:said at least one of the modules is moved by said at least one module carrier to at least one of a plurality of work stations, a position of said at least one of the modules relative to said at least one module carrier is determined by means of a first position detecting device arranged on said module carrier and adapted to determine said position of said at least one of the modules, a relative positioning is performed between members of one pair out of: (i) said at least one module carrier and said at least one of said plurality of work stations, (ii) said at least one module carrier and a further module, and (iii) said at least one of said plurality of work stations and said at least one of the modules, said relative positioning being guided by at least one additional position detecting device arranged on one out of said at least one module carrier and said work station, wherein: the module continues to be held by the holding device in the module carrier while the module carrier is moved to a plurality of working stations in order to carry out a sequence of working steps, and the position of the module relative to the module carrier is maintained for carrying out the working steps.
