Abstract: A photo-resist (21) is applied in a pattern or vertical columns having the dimensions of holes or pores of the aperture plate to be produced. This mask pattern provides the apertures which define the aerosol particle size, having up to 2500 holes per square mm. There is electro-deposition of metal (22) into the spaces around the columns (21). There is further application of a second photo-resist mask (25) of much larger (wider and taller) columns, encompassing the area of a number of first columns (21). The hole diameter in the second plating layer is chosen according to a desired flow rate.

Abstract: An aerosol generator with electrical power conducting pins has a vibratable plate with apertures therein and an annular piezo. An annular support member supports the piezo and the vibratable plate. A first electrical power conducting pin engages directly with a first, top, surface of the piezo. A second electrical power conducting pin indirectly conducts electrical power to a second surface of the piezo, by contacting an extension tab. There is a film of cured epoxy adhesive on the tab. The aerosol generator avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the same lateral and top side of the piezo and support member. The pins may have multi-point tips for particularly effective electrical contact.

Abstract: An aerosol generator (100) has a vibratable plate (1) with apertures therein and an annular piezo (2) which causes movement of the vibratable plate (1). An annular support member (3) supports the piezo (2) and the vibratable plate (1). A first electrical power conducting pin (10) engages directly with a first, top, surface of the piezo (2). A second electrical power conducting pin (11) indirectly conducts electrical power to a second surface of the piezo (2), by contacting an extension tab (103) of the support member (20), also on its top side. There is a film of cured epoxy adhesive on the tab (103), providing excellent gripping force between the pin (11) and the support (3). The aerosol generator (100) avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the on the same lateral and top side of the piezo and support member. The pins may have multi-point tips (50) for particularly effective electrical contact.

Abstract: An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 μm thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.

Abstract: An aperture plate is formed from a palladium nickel alloy comprising about 89% palladium and about 11% nickel. There is a generally fine substantially equiaxed grain microstructure throughout the thickness of the aperture plate. The average grain width (W) is in the range of from 0.2 μm to 5.0 μm, in some cases from 0.2 μm to 2.0 μm. Because the grain structure is equiaxed (L/W=1) the grain length (L) is the same as the grain width. The improved aperture plate extends the life of nebulisers, eliminates the risk of premature and unpredictable failure of a nebuliser in service, eliminates the risk of product returns from hospitals and patients, and eliminates the possible risk of fragments of the aperture plate breaking free from the nebulizer.
