Abstract
An ultra thin piezoelectric quartz crystal package can be realized by using adhesive dollops to compliantly mount a piezoelectric device within a thin package. The adhesive dollops maintain spacing between the upper and lower surfaces of the piezoelectric device (18) and the surfaces (13 and 15) of the housing that is comprised of upper and lower substrates (12 and 14).
