A method of sealing an attachment face of a MST device to a mounting surface on a support member, the attachment face having an aperture connected to a first fluid conduit, the attachment face having a second aperture connected to a second conduit, the method comprising the steps of:n applying a thermosetting adhesive to the mounting surface; aligning the first aperture with at least part of the second aperture; pressing the MST device and the mounting surface together; and, curing the thermosetting adhesive; wherein, the thermosetting adhesive has a viscosity of between 100 centiPoise and 10,000,000 centiPoise. nn Using a thermosetting adhesive instead of a thermoplastic adhesive provides a far more reliable seal. The bond between the thermoplastic adhesive and the MST device surface is prone to thermal fatigue and leakage or outright failure. |
