[0028] The electronic component preferably comprises, particularly in its first housing, at least one sensor element or sensor for rotation rate, acceleration, magnetic fields and in particular an ASIC as a signal processing circuit.

[0034] It is advantageous for additional components, such as a permanent magnet, to be attached to this fixing plate, preferably on the side of the first leadframe, i.e., "hanging" above the at least one electronic component, i.e., on the inside of the electronic component, or alternatively preferably on the other side of the fixing surface facing away from the leadframe.

[0036] The electronic component preferably does not include a carrier which is directly or indirectly attached to the first leadframe and is inserted into an injection mold for overmolding and forming the second housing according to the prior art.
[0037] Preferably, the electronic component comprises a first and a second interconnected leadframe.

[0044] The fixing / shielding element or fixing surface is preferably connected at least at one point to a residual structure of the dambar. Connecting or fastening the fixing surface to one or more residual structures of the dambar has the advantage that these do not perform any electrical circuitry function, unlike most parts of the first leadframe, which would be short-circuited by fastening the fixing surface. Particularly preferably, the fixing surface is connected to a residual structure of the dambar or dambar residual structure that is not directly electrically connected to the first or second leadframe, but is held by the first plastic housing.

[0046] It is preferred that at least one Dambar residual structure is and remains directly connected to the first and / or second leadframe or the first and / or second circuit carrier. In particular, or alternatively, at least one Dambar residual structure is not connected to any of the circuit carriers or leadframes, but only to the fixing shielding element and one or more housings, optionally also to a protective cover.
[0047] The electronic component preferably includes an acceleration sensor element, in particular 1-axis, for relatively low accelerations, up to 5g, as a chassis acceleration sensor element or vehicle dynamics control acceleration sensor element. and / or an acceleration sensor element, in particular single-axis, for relatively large accelerations, at least up to 100g, as an airbag acceleration sensor element.

[0049] Preferably, the first leadframe, together with the first housing and the fixing plate, is arranged in a trough-shaped, prefabricated housing filled with a potting compound, whereby this potting compound and the trough-shaped housing together form the second housing, which in this embodiment is then not produced by injection molding or overmolding, see here. Fig. 4. The trough-shaped premold housing features, in particular, an integrated connector whose contact points or pins are formed by the second leadframe, which is connected to the first leadframe. Furthermore, the trough-shaped premold housing expediently includes a connector collar from which the contact points or pins protrude from the second housing.
[0050] It is preferred that the fixing / shielding element or the fixing plate has side skirts, these serve to shield against electromagnetic radiation from the side and, if necessary, to dissipate heat during the overmolding or overmolding process of the second housing.
[0051] The fixing / shielding element or fixing plate preferably has mechanical stiffening means, such as stiffening ribs or webs. This design is particularly preferred for arrangements with several electronic components that are connected by a common fixing / shielding element or fixing plate for the manufacturing process.
[0052] Advantageously, the fixing / shielding element or fixing plate includes one or more tabs. These serve in particular for transport during the manufacturing process and / or heat dissipation during overmolding and, if applicable, heat dissipation during operation of the finished electronic component, and are designed accordingly.
[0053] The electronic component preferably or additionally preferably comprises at least one actuator element, for example a piezoelectric oscillator or an ultrasonic transducer, as an electronic element.
[0054] It is preferred that the fixing / shielding element or fixing surface is designed as part of the second leadframe.
[0055] The fixing / shielding element or fixing surface expediently has one or more of the following features: - Perforated surface with slotted, oval, or round openings to improve mold flow and for more secure anchoring in the mold. Non-perforated or continuous surfaces, as well as partial openings, are also possible. - Planar or shaped surface. Shaped such that the side surfaces are shielded at least on one side, or deep-drawn pockets are formed over the individual ICs. The fixing surface lies over at least one member of the mold body, covering / shielding in particular at least the ASIC and the at least one sensor element. The shaped surface of the fixing surface is particularly preferably trough-shaped. - Coating with magnetic and / or electrically conductive material to improve the EMC and / or ESD behavior of the IC, for example coating with nickel. - Connected to the IC body's leadframe at least at one point. Suitable connection techniques include soldering, gluing, sintering, crimping, and welding. - Exposed partial areas serve to fix and position the surface during the molding process, so that positioning or gripping tools do not touch the IC body or the first housing during the molding process. - The mounting surface can be fitted with screw-on tabs. Electrically insulated or contacting. - The fixing surface is part of the connector pins or the second leadframe, which has the connector pins of the electronic component. - The fixing surface is pre-assembled in the connector body pre-molded part. The IC body is contacted with this pre-molded part and then molded. - The first leadframe is mounted in such a way that the electronic components mounted on it, such as an IC or sensor elements, are physically located between the first leadframe, especially its component placement area, and the mounting surface. This serves to improve EMC performance. The fixing surface can be made of metal or plastic, with the plastic optionally having an electrically conductive coating. - The fixing surface serves to mechanically stiffen the mold body. - The fixing surface can be flat or curved within the fixing surface. In particular, the fixing surface and the first leadframe are curved uniformly or to match each other. - The fixing surface serves as a mounting surface for additional components, such as magnets.
[0056] Preferably, the first package is treated with plasma before molding to remove contaminants and improve the adhesion of the overmold material to the IC body / first package.
[0057] The first leadframe is preferably bent in the area of the connection pins at a freely selectable angle relative to the first housing and its orientation and thus molded / overmolded.
[0058] The molding process, in particular overmolding, is preferably carried out as an injection mold, transfer mold, RIM, hot melt, compression mold or casting process.
[0059] The fixing / shielding element or fixing surface is preferably positioned in the injection mold via at least one movable positioning pin or hold-down device. During the molding process, these hold-down devices are retracted and the resulting cavities are filled with molding material.
[0060] The fixing / shielding element or shielding plate / fixing surface preferably contains holes and / or cutouts and / or slots for transport, adjustment, and fixing. This is advantageous for the overmold equipment and / or for alignment, fastening, and / or positioning in the injection mold.
[0061] The fixing / shielding element or the shielding plate / fixing surface is preferably designed with side skirts for better EMC protection and as additional heat dissipation (mold flow guide plate).
[0062] The fixing / shielding element or shielding plate / fixing surface can also be used to attach multiple sensors or a common network / bundle / module / cluster of electronic components that share a common fixing / shielding element. This allows the sensors to be positioned very precisely relative to each other.
[0063] By means of special stiffening ribs or shapes of the fixing / shielding element or the fixing surface, increased stiffness can preferably be achieved and a curvature of the network / bundle / module / cluster of electronic components as a result of the overmold process can be prevented.
[0064] The fixing / shielding element or shielding plate / fixing surface preferably includes features that act as a clamping device. This secures the first package or IC so that it remains in place on the fixing plate or fixing surface during subsequent process steps. Additionally, the clamp serves as a heat sink / heat conductor during the overmold process and during operation.
[0065] The fixing / shielding element or shielding plate preferably has additional plastic clips applied to secure the first package or IC. These clips also provide thermal insulation during the overmold process. They can be molded, glued, or mechanically attached (e.g., riveted) to the fixing plate.
[0066] Preferably, in addition to or as an alternative to the sensor elements for the rotation rate and acceleration, other sensor elements, at least one other sensor element, for physical measured quantities, such as pressure, magnetic fields, temperature, sound, structure-borne sound, can also be used in the IC or first package.
[0067] The decoupling sleeve or protective cover is advantageously formed partially or completely. This sleeve serves in particular to stress-decouple the first housing and is designed accordingly, with this stress arising from temperature changes between the first housing and the overmold material. Additionally, it acts as a heat shield during the overmold process by preventing direct contact between the first housing and the overmold material. The encapsulation material is most preferably a soft, elastic material, e.g., silicone or polyurethane, especially silicone gel.
[0068] The invention also preferably relates to an arrangement in which a common fixing / shielding element or a common fixing surface connects several electronic components. The fixing surface particularly includes retaining elements, such as holes / index holes or slots, with which the entire arrangement can be moved or transported during production, especially on a common conveyor belt.
