WebHistorically, flip chip connoted the use of small solder bumps, typically measuring 75 to 130 µm. The new wafer-level package (WLP) technology uses larger solder balls, typically measuring 300 to 500 µm in diameter. Solder bumped flip chips typically use solder spheres to connect the device directly to the circuit board. WebFor of flip chip dies, two bump constructions can be distinguished: Direct Bump: A copper pillar bump is placed on top of the IO without a repassivation layer. The Under Bump Metallization (UBM) is within the die passivation opening and provides adhesion and acts as barrier layer. Figure 1 shows an example of such construction with copper pillar.
