Abstract
In an inkjet print cartridge having a polymer nozzle member with windows formed therein for facilitating bonding of conductors to electrodes on a substrate, an adhesive is dispensed through the windows to encapsulate the exposed conductors bonded to the electrodes. The adhesive typically overflows outside the windows. To prevent the adhesive from flowing uncontrolled towards the nozzles formed in the nozzle member, a disruption or surface discontinuity is formed in the nozzle member surface between the windows and the nozzles. This disruption or surface discontinuity may be formed by either scratching, etching, cutting, pressing a blade into, or laser ablating the tape surface, or forming a raised wall on the tape surface, such that the flow of adhesive is inhibited because of mechanical and surface forces.
