    摘要： A method for pretreating a solder surface for fluxless soldering is disclosed. The method uses a noble fluorine gas to remove surface oxides from solder surfaces, without the use of external stimulation. A noble fluorine gas is suffused across the solder surface to reduce or eliminate or chemically convert the surface oxides. The process can take place at atmospheric pressure and room temperature. A simple belt driven transport may be used to move the parts past a nozzle which emits the vapor in a system similar to a conventional solder reflow machine.

    摘要： A fluxless soldering sample pretreating system includes a sample chamber having an opening therein and a sample holder. A sample chamber extension extends outwardly from the opening to define a passageway from the sample chamber extension, through the opening, and into the sample chamber. A fluorine-containing gas is supplied into the sample chamber extension. Am energy source such as a microwave oven surrounds the sample chamber extension. The microwave oven produces microwave energy in the sample chamber extension to form a plasma therein and dissociate the fluorine-containing gas into atomic fluorine. A perforated aluminum plate extends transversely across the passageway and blocks the plasma from traversing the passageway from the sample chamber extension into the sample chamber, while allowing the atomic fluorine to traverse the passageway from the sample chamber extension into the sample holder. A second chamber extension, gas supply and microwave oven may be added to improve uniformity for large samples.

    摘要： The invention comprises curing polyamic acid solutions into polyimide solutions by adding a hydrophilic reagent to a polyamic acid solution. The hydrophilic reagent is selected to have little or no reactivity with amines or carboxylic acids, and is of the type that will react with water to form by-products that shift the equilibrium between polyamic acid as a reactant and polyimide and water as products toward the production of polyimide.

    摘要： A photoresist composition is disclosed that comprises an organic resin that is thermoset by acid catalysis and a photoactive, etch-resistant ionic modifier formed of an anion and a cation. The modifier is present in the organic resin in an amount effective to produce substantial photoreactivity and etch resistance in a mixture of the resin and the modifier. The cation will, upon exposure to electromagnetic radiation, produce a species that is weakly basic or neutral, and the anion will, upon exposure to electromagnetic radiation, produce an acid precursor that will form a relatively strong acid in an acid-base solvent system. As a result, the relatively strong acid will catalyze the organic resin upon exposure to an appropriate frequency of electromagnetic radiation and the relatively weak base or neutral species formed by the cation will not substantially neutralize the acid or interfere with the acid catalyzed reaction of the organic resin.

    摘要： A microelectromechanical transducer including a plurality of strips arranged in an array and maintained in a closely spaced relation by a plurality of spacers. An electrically conductive layer on portions of the strips and spacers distributes electrical signal within the transducer to cause adjacent portions of the strips to move together. The strips and spacers may be formed from a common dielectric layer using microelectronic fabrication techniques. Two transducers may be coupled at an angle offset from parallel for two-dimensional micropositioning. A photodetector and Fresnel lens may be combined with the micropositioner using the transducers for optical scanning microscopy.
