Definitions

  • the invention relates to a mold housing for an electronic circuit according to the preamble of claim 1.
  • Mold housings for receiving electronic circuits are known.
  • a chip housing they are used for example for receiving sensor chips or similar circuits use.
  • Their advantage lies in the complete encapsulation of the integrated circuits.
  • the housing forms known in the prior art have in common that they are contacted via laterally protruding from the housing leads (leads). Via these leads, the chip housings are mounted and / or contacted in a standard assembly (SMT) by means of a soldering process on a printed circuit board or on a substrate.
  • SMT standard assembly
  • a disadvantage of these known types of construction is that the mounting or contacting via the connection leads (leads) must take place on printed circuit boards or on a substrate, which means complicated, complicated to control and also error-prone mounting steps.
  • the connection leads (leads) must take place on printed circuit boards or on a substrate, which means complicated, complicated to control and also error-prone mounting steps.
  • the connection leads (leads) must take place on printed circuit boards or on a
  • the object of the invention is to provide a mold housing for electronic circuits, which avoids the disadvantages mentioned.
  • a mold housing for an electronic circuit for installation in electronic devices and / or applications, in particular sensors or transducers is provided which has press-in zones.
  • press-fit zones are areas in / on the mold housing which, in the broadest sense, serve the use of press-fit technology.
  • Press-fit technology is understood to mean any form of assembly which comprises the cold connection of at least two components with the application of pressing force.
  • the press-fit zones are designed as electrical contact points.
  • the electrical contacting of the provided in the mold housing electrical / electronic circuit is therefore carried out in the region of the press-fit.
  • the press-in zones are designed as redundant electrical contact points. This means that a greater number of electrical contact points on the housing housing is required for proper contacting of the electrical / electronic circuit located in the mold housing. It is therefore optional during assembly of the mold housing, whether one or the other electrical contact point is used for contacting. Here, a considerable degree of freedom is gained in the assembly process.
  • the press-fit zones are designed as mechanical fixing devices. Consequently, the press-in zones also serve to fix the mold housing during installation in the mentioned electronic devices and / or applications. Further attachment of the mold housing, for example by screwing or soldering is not required.
  • the press-in zones are designed both as electrical contact points and as mechanical fixing devices, that is to say both Fulfill functions. Especially when using redundant electrical contact points, it is readily possible to use part of the press-in zones for making electrical contact, while another part is only used for mechanically fixing the mold housing in the application.
  • the press-in zones have a substantially circular cross-section.
  • press-in zones are designed as substantially frusto-conical
  • Recesses are formed in the mold housing.
  • Essentially frusto-conical means that the press-fit points on an outer side of the mold housing (surface area) have a larger circular cross-section than more toward the middle or the lower side of the mold housing.
  • the mold housing comprises a position aligner.
  • a position aligner in this case is any device which is suitable for defining the position of the mold housing relative to a specific reference plane or to a specific reference point, preferably to define it mechanically.
  • a position aligner may be formed as a nose or as a recess.
  • the press-in zones are arranged symmetrically to each other.
  • the press-fit zones on the mold housing in such a way are formed so that they have a symmetrical or at least substantially symmetrical configuration to each other. In this case, they have for example at a certain point of the mold housing and mutually equal distances or similar angles.
  • the press-in zones are arranged symmetrically to the position aligner.
  • a multi-shaped use one and the same mold housing can be achieved, the use of which can be determined for example via the position aligner.
  • the press-in zones preferably electrically redundant press-in zones, are in each case contacted in the required manner.
  • the contact points are contactable both from an upper side and from an underside of the mold housing.
  • a contacting can therefore take place both from the top and from the bottom of the mold housing, wherein not necessarily the top side contact is electrically equivalent to the bottom side contact. If the top and bottom contacts are electrically the same, then one degree of freedom in the type of contact can be achieved. If the top and bottom contacts are not electrically equivalent (each results in different contacts), this can increase the effective number of contacts.
  • the press-in zones have bores.
  • the mold housing is a standard mold housing, for example a standard Plastic Quad Fiat Pack (PQFP) as is already known in the prior art. But he has no or only very short leads. If the contacting takes place exclusively via the contact points mentioned in the press-in zones, the use of leads, which are required for PCB assembly, is superfluous. The leads are therefore omitted or, if installed on conventional production lines, located close to the housing. If, however, a further contacting is also desired via leads for a particular application, leads of the required length and required number can be left on the mold housing.
  • PQFP Plastic Quad Fiat Pack
  • the press-in zone is associated with a press-in component, which is mounted on a die pad of the mold housing, in particular welded.
  • the press-in zone mentioned corresponds to a press-fit component which is mounted, in particular welded, as an electrical connection or already as an electrical component within the mold housing, namely on a die pad.
  • the press-fit component is in particular a metallic insert which accomplishes the electrical connection to the circuits arranged in the mold housing and optionally further components.
  • the die-pad has receiving zones for the press-fit components.
  • the press-fit components are thereby accommodated in a specific spatial arrangement in the mold housing.
  • the die pad has a receiving structure for aligning and / or fixing the press-fit components.
  • the press-fit components are thus already aligned or fixed on the die pad before the actual fastening process (that is to say welding, for example), so that further assembly without problems is possible.
  • the invention further comprises an electronic module, in particular an acceleration sensor, in particular for motor vehicle technology, with a mold housing according to one of the preceding claims.
  • an electronic module in particular an acceleration sensor, in particular for motor vehicle technology
  • Fixing device preferably connected to a position aligner, mold housing in different orientations with one and the same basic element as a component.
  • an acceleration sensor can be displayed in the X direction and in the Y direction, with only one sensing direction being required, and only the mold housing comprising the actual acceleration sensor being rotated by 90 degrees. This can be achieved advantageously via the position aligner. Assembly and storage of components are thereby drastically simplified and cheapened.
  • the mold housing is electrically contacted in the electronic module having a cavity by means of at least two press-in pins corresponding to the press-in zones.
  • the electrical contacting is thus carried out by Einpastepins, so essentially rod-shaped formations within a cavity in the electronic module, which correspond to the press-in zones of the mold housing and enter into electrical connection with this once the mold housing in the electronic module is introduced.
  • a further electronic contacting, for example via lead pins and printed circuit boards, is not required here.
  • the press-fit pins are designed as a mechanical fastening device.
  • the press-fit pins which are described above for electrical contacting, thus also form a mechanical fastening device for the mold housing within the electronic module.
  • the electronic module has Einpresspins, which are designed exclusively as a fastening device, but not as a contacting device. Consequently, there are additional press-in pins within the cavity of the electronic module, which, however, do not serve to make electrical contact with the mold housing, but (for example in the case of redundant press-in zones) merely perform a fastening function for the mold housing within the electronic module. This happens, for example, in that the press-in pins have no electrical contact with other press-fit pins or with other contact points.
  • the electronic module has a position determiner.
  • a device is preferably meant in the cavity of the electronic module, which allows in conjunction with the position aligner on the mold housing a spatial orientation of the mold housing within the electronic module.
  • the combination position aligner / position determiner is chosen so that a unique and unmistakable positioning, in particular automatically, is possible. This is done in particular by using corresponding recesses / noses.

  • leads 8, which are produced in the usual manner of manufacture by means of a lead frame, not shown here, and in the present case are cut directly on outer edges 9 of the mold housing 1.

  • the press-fit components 12 in turn have punched holes 15 (FIG. which, of course, can be produced by a punching process as well as in all other processes which give corresponding penetrations).
  • the cutouts 15 have a smaller cross-section than the holes 6, so that there is a covering zone 16, in the region of these covering zones 16 is thus a ring part of the respective
  • Press-in component 12 is not covered by the mold housing 1, but is open.
