摘要:
By suitable retardation oral pharmaceutical compositions containing propiverine or one or several pharmaceutically acceptable salts thereof in an amount of 4 mg to 60 mg propiverine and having a prolonged release of the active agent are produced. Preferably a blend of active agent and optionally one or more acidic substances having a pKa value of less than 6.65 are provided with a retarding coating or are embedded in a matrix which is then optionally coated with further retarding layers.
摘要:
A system, method, and apparatus for injection molding conductive bonding material into a plurality of cavities in a surface are disclosed. The method comprises aligning a fill head with a surface. The mold includes a plurality of cavities. The method further includes placing the fill head in substantial contact with the surface. At least a first gas is channeled about a first region of the fill head. The at least first gas has a temperature above a melting point of conductive bonding material residing in a reservoir thereby maintaining the conductive bonding material in a molten state. The conductive bonding material is forced out of the fill head toward the surface. The conductive bonding material is provided into at least one cavity of the plurality of cavities contemporaneous with the at least one cavity being in proximity to the fill head.
摘要:
A system, method, and device for applying conductive bonding material to a substrate are disclosed. The method includes providing conductive bonding material in a plurality of cavities of a mold. A total number of cavities in the plurality of cavities being greater than a total number of at least one conductive pad of a circuit supporting substrate corresponding to the mold. The conductive bonding material in the mold is heated to a reflow temperature of the conductive bonding material. At least one wettable surface is placed in substantial contact with the heated conductive bonding material in at least one cavity. The mold and the corresponding circuit supporting substrate are brought in close proximity to each other such that the heated conductive bonding material in at least one cavity comes in contact with at least one conductive pad of the corresponding circuit supporting substrate.
