    摘要: Methods for forming stud bumps and apparatuses for forming stud bumps are disclosed. According to an embodiment, a method includes clamping a wire with a clamp. The clamp includes at least two opposing plates, and at least one of the opposing plates includes a protruding feature that intersects the wire when the wire is clamped forming a first notch in the wire. The method further includes bonding the wire to a bonding surface, releasing the wire from the clamp, passing the wire a notch pitch distance through the clamp, clamping the wire with the clamp forming a second notch in the wire, and breaking the wire leaving a bonded portion of the wire on the bonding surface. The second notch is the notch pitch distance from the first notch along the wire.

    摘要: A mold includes a top portion, and an edge ring having a ring-shape. The edge ring is underlying and connected to edges of the top portion. The edge ring includes air vents. The edge ring further encircles the inner space under the top portion of the mold. A plurality of injection ports is connected to the inner space of the mold. The plurality of injection ports is substantially aligned to a straight line crossing a center of the top portion of the mold. The plurality of injection ports has different sizes.
