WebThe electrical interconnection between substrate surface and pads over chip can be spread out as a zone array, as opposed to around the chip that is a particular design for wire bond arrangement. This two dimensional structure can reduce chip footprint over substrate and reduce chip space. WebAug 28, 2024 · The bond load should be just enough to seat the chip properly on the substrate. To ensure good reflow, each of the chip bumps must be touching a bond pad on the substrate. When flux cannot be used to hold the chip in place during reflow, a machine with elevated stage temperatures and higher bond loads should be used (Figure 6). Bondwires usually consist of one of the following materials: • Aluminum • Copper • Silver • Gold diatoma earth
