LASER CUTTING AND JOINING A FLUORINATED POLYMER MEMBRANE TO A POLYMER FRAME

摘要

Method and apparatus for cutting a fluorinated polymer membrane and simultaneously joining it to a polymer frame. The method comprising the steps of: (i) contacting a fluorinated polymer membrane with a polymer frame at the point where a cut and join is desired, and (ii) directing at least one laser beam onto the point of contact between the membrane and the frame so as to cut the membrane and effect a join to the frame.
