A method for manufacturing a golf club head with a disparate metallic material provided on a hosel side of the head, which can improve degree of freedom in the design of a head. 1 to 100 \u03bcm in which-fibrils are intertwined, the fibrils being graphite fibrils of a fiber diameter of 0. A thermally conductive can is between the heat sink and spool such that the working fluid flows between the can and spool. The bit cell pass-gates are electrically coupled to a bit-true and a bit-compliment line pair along each particular column.
