A sensor module, in particular for measuring an acceleration or rotational speed, having a housing base body made of a plastic material, a lead frame extending through the housing base body and having leads which have connector pins for attachment to a circuit board, a sensor system having at least one sensor chip, the sensor system being in contact with the lead frame via conductor bonds, a cover, which is connected to the base body and at least one connector pin and is made of a conductive material. A simple construction having a high shielding effect is achieved due to the fact that the conductive cover is connected to the connector pin. The cover, a lid, for example, may be contacted directly via the connector pin together with the other connector pins when the components are mounted on the circuit board. The sensor module may be molded or may have a premolded housing. The edge or a contact of the cover may be welded, soldered, glued, or pressed to a ground lead of the lead frame.

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.

It is proposed that the lid part is produced as a metal punched part, the punched edge of the lid part having a punch ridge on a first side of the lid part and a punch indentation on a second side opposite the first side, and the lid part being pressed into the opening of the housing part via the second side so that the lid part comes to rest against assigned sections of the inner wall of the opening via at least two edge sections that are distributed around the perimeter of the lid part and bites into the assigned sections of the inner wall in a barb-like manner via the punch ridge.
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.

The invention proposes a device for measuring the mass of a flowing medium, in particular the mass of air aspirated by internal combustion engines. The device has a platelike sensor element which is accommodated in a recess of a sensor carrier, and which with a sensor region that has at least one measuring resistor is exposed to the flowing medium in order to measure its mass. The sensor element is accommodated essentially flush in the recess and is retained in the recess by being glued to a bottom face in the recess. The bottom face of the recess of the sensor carrier has a troughlike indentation, which extends at least partially along the circumference of the sensor element outside the sensor region that has the at least one measuring resistor. The device according to the invention is intended to measure the mass of a flowing medium, in particular for measuring the mass of air aspirated by internal combustion engines.

An electromagnetic compatibility (EMC) filter used in a hybrid technology circuit component, having current-carrying lines and a ground conductor, for protection against electromagnetic interference. The current-carrying lines and ground conductor are arranged on a ceramic plate. The current-carrying lines are covered by a dielectric, which in turn, is covered by an upper metal screen in electrical contact with the ground conductor. A lower metal screen is arranged on the ceramic plate beneath the current-carrying lines and is in electrical contact with the ground conductor.

摘要:
An electronic device, including a housing part having at least one closable opening and one plug-in part, the housing part accommodating a printed circuit board, which has at least one electrical and/or electronic component arranged thereon, and electrical contact elements, which are electrically connected to the plug-in part, and which have ends in the housing interior that run parallel to each other and protrude in the direction of the at least one opening, the ends being passed through contact openings of the printed circuit board and being connected conductively to the printed circuit board. To protect impact-sensitive and vibration-sensitive components, it is proposed to provide the contact elements, on a part of their length not inserted into the contact openings, with elastically deformable segments and to flexibly support the printed circuit board in the housing part by the contact element configured in this way, and, additionally, to connect it via damping elements at least indirectly to the housing part.
