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.
