ABSTRACT:
Disclosed is a header which may be used on a disc drive base or on another such plate between a higher pressure space and a lower pressure space and which will effectively prevent or retard pressure loss from the higher pressure space. A molded plastic wafer member is positioned in an aperture in the plate. A fiberglass reinforced polymer board member is superimposed over the wafer. There are axially aligned transverse apertures in the board member and the wafer member and conductive pins pass through these aligned apertures. Adjacent the apertures in the board member are metallized surfaces and the pins are soldered to board member at this point to effect the pressurized seal.
