Laser transmission laminating of materials for ink jet printheads

摘要

A method for assembling a printhead such as an ink jet printhead can include the use of a laser to bond two or more printhead layers together. In an embodiment, a laser beam is directed through a transparent layer to an energy-absorbing layer, where the energy-absorbing layer is melted such that after removal of the laser beam the melted layer solidifies to adhere the energy-absorbing layer to the transparent layer. In another embodiment, heating the energy-absorbing layer melts the transparent layer to adhere the energy-absorbing layer to the transparent layer after removal of the laser beam. The laser transmission lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

主权项

1. A method for forming an ink jet printhead, comprising:
placing an energy-absorbing layer in physical contact with a transparent layer; directing a laser beam through the transparent layer to contact the energy-absorbing layer with the laser beam; and curing at least one of the energy-absorbing layer and the transparent layer to physically attach the energy-absorbing layer to the transparent layer and to form at least a portion of an ink jet printhead.
