Abstract: A semiconductor package carrier board, a method for fabricating the same, and an electronic package having the same are provided. The method includes forming on a circuit structure a graphene layer that acts as an insulation heat dissipating layer. Since the heat conductivity of the graphene layer is far greater than the heat conductivity of ink (about 0.4 W/m·k), which is used as solder resist, the heat of the semiconductor package carrier board can be conducted quickly, and thus can avoid the problem that the heat will be accumulated on the semiconductor package carrier board.

Abstract: A grinding wheel center hole protection pad is provided, which mainly include a positioning portion attached to the peripheral thereof and the guiding portions disposed at the center hole at the axial center thereof.

Therefore, the grinding wheel can be closely attached to the flange plate during the assembling process to decrease eccentricity. Accordingly, it is not necessary to perform the cutting calibration process and balance adjustment by a cutting machine, which can reduce the waste of manpower and material resources.

Abstract: A stamping head includes a stamping portion and a connection portion connected to the stamping portion. The stamping portion includes a top surface and four side surfaces. The stamping head defines a jag extending from a junction between a specific one of the side surfaces and the top surface toward a centre of the top surface. The jag passes through the specific side surface. When the stamping head presses a ACF onto a ceramic substrate, a residual air between the ACF and the ceramic substrate flows outside through the jag.
