Abstract
A method of making a microfluidic module is disclosed that includes forming a fluid flow channel in a self-bonding rebondable polyimide film to provide a channel sheet, the self-bonding rebondable polyimide film having a first mask layer self-bonded thereto; removing the first mask layer from the channel sheet after forming the fluid flow channel; and self-bonding the surface of the channel sheet exposed by removal of the first mask layer to a cover sheet.

A method of making a microfluidic module comprising:
- providing a self-bonding polyimide film having a first major surface and a second major surface;
- bonding, without adhesive, the first major surface of the self-bonding polyimide film to a first mask layer;
- forming a fluid flow channel in the self-bonding polyimide film,
- removing the first mask layer from the first major surface of the self-bonding polyimide film after forming the fluid flow channel;
- and
- re-bonding, without adhesive, the first major surface of the self-bonding polyimide film, exposed by removal of the first mask layer, to a first cover sheet.
