Claims11
A method of fabricating a module having fluid flow channels in communication with a diaphragm valve which comprises applying a release agent to a surface of a first sheet of an adhesiveless self-bondable thermoset polyimide in a region corresponding to said diaphragm valve, assembling said first sheet with a second sheet of adhesiveless self-bondable thermoset polyimide, one of said first and second sheets having a channel formed therein, which is in fluid communication with said diaphragm valve;
- and interfacially and directly bonding said first sheet to said second sheet except in said region corresponding to said diaphragm valve without using an adhesive.
