Abstract
A vacuum chamber housing a cooled CCD for a CCD camera has a hermetic seal provided by a closed loop pattern on the surface of a laminate, printed circuit board having subteranean conductor traces. Electrical access to the CCD is provided, via the traces, by a universal pattern of pivouts subsets of which correspond to the pin patterns of different CCDs. Large numbers of pin connection patterns are achieved by this technique without leaks. A single board embodiment and a mother-daughter board embodiment are described.
