    Abstract: A process is provided for the manufacture of thin walled ceramic structures, particularly conical or near conical shaped structures. The process involves a tape casting technique wherein a green tape is prepared from a colloidal suspension containing a ceramic powder, a binder system, a plasticizer and a solvent. The suspension is cast into a thin sheet and dried to form a pliable tape. The tape is cut into planar, shaped pieces. Non-planar components of the final structure are preformed from the cut planar tape pieces into predetermined three-dimensional shapes. The planar and preformed components are sequentially assembled within a die and compacted under pressure to form a green body. The green body is subjected first, to a burnout cycle to form a brown body, and then sintered to form the unitary, cohesive, thin walled ceramic structure.

    Abstract: A connective medium for use in ball grid arrays for connecting electronic devices to circuit boards comprising high melting point solder alloy spheres (32) coated, by electroplating, with an outer concentric layer of a lower melting point solder alloy (34) of uniform thickness. In a further aspect, a leach barrier (30) is coated on the high melting point solder alloy (32) prior to electroplating the low melting point solder alloy (34) thereto. The leach barrier (30) forms a barrier to prevent the lead from leaching from the high melting point lead solder spheres (32) into the low melting point solder alloy (34) during the reflow heat treatment in the mounting process.

    Abstract: A microtitre plate containing a plurality of wells for conducting immunoassays wherein one or more of the sides, bottom and lid walls of each well are formed with a reflective, metallized surface. The surface may be an inner coating on the walls of clear or opaque plates, or an outer coating on the walls of clear plates. Alternatively, the plate may be formed, for example, by stamping from a reflective metal material. Improved sensitivity in photometric detection results from photon emitting immunoassays conducted inthe plate.
