Webadhesive. Once firmly in place the wire bond process electrically connects the die bond pads to the associated wiring pattern on the substrate. The wire bond machine welds fine wires, typically of Al or Au, between each pad on the chip and the appropriate pad on the substrate. Wire bonding demands clean pads on both the chip and the WebWire-bond mechanisms offer three different methods for imparting the requisite energy to attach a wire to the bond site: thermocompression, ultrasonic, and thermosonic. Two types of bond methods exist: the ball-stitch and the wedge bonds (Table 1). table 1. Comparison of wire-bonding methods by bond type. Click here to enlarge image null WebAn analysis of the dependence of packaging cost on die cost is shown in Fig. 5a for three different values of assembly yield (99%, 99.5%, and 99.9%). As the die cost increases, the cost of packaging increases, and when the die cost is $20, the flip chip BGA cost with a 99% assembly yield is three times higher than a wire bonded BGA/CSP with a ... dg the final gate 2022
