Abstract
A progressive stencil printing system and method for applying encapsulant onto an inkjet printhead body is described. The system relates to a continuous stencil printing apparatus that can print encapsulant on different types of inkjet printhead bodies and clean the stencil during production.
Claims22
A stencil printing system for applying encapsulant onto an inkjet printhead body comprising:
- a stencil film comprising a first stencil pattern and a second stencil pattern, each of the stencil patterns corresponding to a pattern of encapsulant adhesive to be applied onto an inkjet printhead body,
- a first drive device coupled to the stencil film to move the film along a given path;
- an encapsulant-dispensing device for applying encapsulant to a printhead body through one of the first and second stencils,
- wherein the encapsulant-dispensing device applies encapsulant through the first stencil onto a first printhead body and the encapsulant-dispensing device applies encapsulant through the second stencil onto a second printhead body.

A method for applying encapsulant onto an inkjet printhead body comprising:
- providing a stencil film comprising a first stencil pattern and a second stencil pattern, each of the stencil patterns corresponding to a pattern of encapsulant adhesive to be applied onto an inkjet printhead body,
- aligning the first stencil pattern with a first printhead body;
- dispensing encapsulant to the first printhead body through the first stencil pattern,
- indexing said stencil film to align the second stencil pattern with a second printhead body;
- and
- dispensing encapsulant to the second printhead body through the second stencil pattern.
