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). WebWhat is a bond pad? A bonding pad is used to connect the circuit on a die to a pin on a packaged chip. One side of a gold wire connects to the bonding pad while the other side connects to the package. …. This arrangement allows connection from the core of the chip to the pad and, in turn, the outside world using any metal layer.
