Abstract
A method and apparatus for assembling an inkjet printhead is disclosed. The apparatus comprises one or more microheater resistors and a material, which can be reflowed by use of the heat generated by the microheater, disposed proximate to the heater resistor. The microheater resistor comprises a heater resistor with an input port and an output port. A first electrical conductor, coupled to the input port of the heater resistor, receives a first voltage and a second electrical conductor, coupled to the output port of the heater resistor, receives a second voltage. A curing effect in the adhesive is produced by heat generated in the heater resistor when electrical current flows through the resistor in response to an application of a first voltage to the first electrical conductor and a second voltage to the second electrical conductor.
