A method of attaching MST devices to a support member via an adhesive film, the MST devices each having an attachment face with a first aperture and the support member having a mounting surface with second apertures corresponding to each of the first apertures respectively and a fiducial marker for each of the MST devices respectively, and the adhesive film having a plurality of openings. The method involving positioning the adhesive film using the fiducial marker and the corresponding opening such that the openings register with at least part of the second apertures in the mounting surface, applying the adhesive film to the mounting surface, positioning each of the MST devices relative to the respective openings, and, attaching the MST devices with heat and pressure such that the openings establish the respective first and second apertures.
