Printed Circuit Board Photography
This work is an important part of the Department's activities because it
produces the negatives from which the Printed Circuit Boards and
component location artwork are produced, some of them with very fine
detail. A constant check is kept of the performance of the camera which
has been carefully installed and modified by the Department for this
work so that the necessary accuracy can be maintained. Errors are
usually no creater than O.lmm in a dimension of 25cm.
The minicomputer-controlled caption generating system designed for the
subtitling of foreign feature films is now being used to caption operas
and foreign language teaching programmes. The computer programmes were
written as part of the design project and are now being extended to
experiment with subtitles for the deaf.
