摘要：
In a printhead assembly (26), a nozzle plate (44) is bonded directly to special traces (38) formed on a flexible tape automated bonding (TAB) circuit (28), using a commercially available automatic lead bonder (96), to retain the nozzle plate (44) in place on the TAB circuit (28). The TAB circuit (28) is handled in a reel-to-reel film format which is commonly used for electronic chip packaging. In a next step of the reel-to-reel process, an automatic bonder (100) manipulates individual substrates (46), aligns each substrate (46) to an associated nozzle plate (44), and bonds electrodes (54) on the substrate (46) to corresponding leads (30) formed on the TAB circuit (28). In the process of the automated bonder (100) aligning the substrate (46) to the nozzle plate (44), the substrate (46) is automatically aligned with respect to the leads (30) on the TAB circuit. Commercially available automatic bonding equipment can be used to perform the alignment and bonding steps.
