摘要:
From tungsten or molybdenum powders, a tungsten or molybdenum compact is pressurized and molded into the same dimensions as or slightly larger than the end product and sintered into tungsten or molybdenum skeleton. After copper infiltration, chemical copper etching is applied to remove excess surface copper. A machining allowance with an absolute value >0-≦0.1 mm may be applied for the machining of uneven surfaces resulting from the chemical process of copper removal.

Techniques for bonding two disks with a minimized eccentricity (ECC) are disclosed. A positioning header includes an ECC controlling structure that further includes a positioning header. In one embodiment, the position header includes three members that form a round stand with a diameter smaller than the inner diameter of the disks. The round stand expands to the inner diameter of the disks to close the gap as a result of the difference between the two diameters when the three members are caused to expand. In one embodiment, the movement of the three members is controlled by magnetic means. Depending on the positions of the ECC controlling structure, the three members are expanded from or restored to their default positions.
