    摘要: A method for producing a pressure sensor, in which a semiconductor pressure pick-up is mounted on a mounting section of a lead grid, in particular a leadframe. The semiconductor pressure pick-up is electrically connected to contact sections of the lead grid. The lead grid, together with the semiconductor pressure pick-up, is inserted into an injection molding die. A die part is brought into contact at the side of the semiconductor pressure pick-up facing away from the mounting section or at side of the mounting section facing away from the semiconductor pressure pick-up. The semiconductor pressure pick-up in the injection molding die is subsequently enclosed by a housing made of mold compound. In order to prevent the mounting section from giving way, it is proposed to clamp the mounting section of the lead grid in the injection molding die when producing the housing.

    摘要: In a method for manufacturing a pressure sensor, in which a semiconductor pressure sensing element is applied to an assembly segment of a lead grid, the semiconductor pressure sensing element is electrically connected to contact segments of the lead grid. The lead grid having the semiconductor pressure sensing element is inserted into an injection molding die, and then the semiconductor pressure sensing element, in the injection molding die, is surrounded by a housing made of injection molding compound. A structure is present in the injection molding die through which a pressure feed for the semiconductor pressure sensing element is left free from the jacket of injection molding compound. A stamp is arranged in the injection molding die so as to be separated by a gap from the side of the assembly segment that is facing away from the semiconductor pressure sensing element or from the side of the semiconductor pressure sensing element that is facing away from the assembly segment. As a result of a change in the temperature of the stamp relative to the temperature of the liquefied injection molding compound, a reduction in the flow capacity of the injection molding compound in the area of the stamp is brought about and, as a result, at least a complete penetration of the injection molding compound into the gap is avoided.
