Die Erfindung betrifft Packages im Elektronikbereich mit elektrischer Schirmung, und hier insbesondere leadless Packages sowie Verfahren zu deren Herstellung.The invention relates to packages in the electronics sector with electrical shielding, and in particular leadless packages and methods for their production.
Im Elektronikbereich, insbesondere im Bereich integrierter Schaltungen, versteht man unter einem ”Package” eine konstruktive Gehäusebauweise zur Aufnahme eines IC (”Integrated Circuit). Seit längerem bekannt ist hierfür die Verwendung von Packages mit Pins oder Leads (”Beinchen”) beispielsweise in Form von SOICs (”Small Outline Integrated Circuits”). Bei derartigen Packages wird ein Substrat als Träger von Schaltungselementen beispielsweise zumindest auf seiner Oberseite in Kunststoff eingefasst bzw. ”gemolded”. Molded Packages sind hochgradig standardisiert und daher kostengünstig in der Herstellung.In the field of electronics, in particular in the field of integrated circuits, a "package" is understood to mean a constructive housing design for accommodating an IC ("integrated circuit"). For a long time, the use of packages with pins or leads ("legs") has been known for this purpose, for example in the form of SOICs ("Small Outline Integrated Circuits"). In such packages, a substrate as a carrier of circuit elements, for example, edged or "molded" in plastic at least on its upper side. Molded packages are highly standardized and therefore cost-effective to manufacture.
In neuerer Zeit setzen sich vermehrt leadless Packages durch, d. h. Packages ohne Pins bzw. ”Beinchen”. Bekannte Bauformen sind etwa QFN („Quad Flat No-lead”) oder LGA (”Leadless Grid Array” oder ”Land Grid Array”). Solche Packages sind kleiner und werden daher generell für Anwendungen mit begrenztem Einbauplatz verwendet wie beispielsweise Consumer-Anwendungen oder Sensoranwendungen im Bereich Automotive.In recent times leadless packages are increasingly prevalent, i. H. Packages without pins or "little legs". Known designs are QFN ("Quad Flat No-lead") or LGA ("Leadless Grid Array" or "Land Grid Array"). Such packages are smaller and therefore generally used for limited-bay applications such as consumer applications or sensor applications in the automotive sector.
In vielen Fällen besteht die Anforderung, ein Package zu schirmen. So reagieren beispielsweise Sensoranwendungen häufig empfindlich auf EMV(”Elektromagnetische Verträglichkeit”)-relevante Einstrahlungen. Auch gibt es RF(”Radio-Frequenz” bzw. Funkwellenabstrahlung)-Anwendungen, die eine starke Abstrahlung haben und zur Vermeidung von Störungen der Umgebung ebenfalls geschirmt werden müssen. Ein leadframebasiertes Package mit Beinchen kann mittels ”inverted leadframe” mit einem EMV-Schirm versehen werden. Für leadless Packages besteht eine derartige Möglichkeit nicht.In many cases there is a requirement to protect a package. For example, sensor applications are often sensitive to EMC ("Electromagnetic Compatibility") - relevant radiation. There are also RF ("Radio Frequency") applications that have high levels of radiation and must also be shielded to avoid interference with the environment. A leadframe-based package with legs can be provided with an EMC shield by means of an inverted leadframe. For leadless packages, such a possibility does not exist.
Stand der Technik für eine EMV-Schirmung eines LGA ist eine Metallkappe, die anstelle des Molds auf dem Substrat aufgelötet oder aufgeklebt wird. Das entsprechende Herstellungsverfahren ist allerdings teuer. Darüber hinaus besteht bei großen Packages das Risiko einer Substratdurchwölbung, weil eine Stabilisierung durch den Moldkörper entfällt.The state of the art for an EMC shield of an LGA is a metal cap, which is soldered or glued on the substrate instead of the mold. However, the corresponding manufacturing process is expensive. In addition, there is the risk of Substratdurchwölbung with large packages, because a stabilization by the Moldkörper deleted.
Eine weitere bekannte Ausführung umfasst ein Metallgitter, das ebenfalls auf das Substrat bestückt und anschließend eingemolded wird. Diese Variante ist ebenfalls vergleichsweise teuer und benötigt zusätzlichen Platz im Package für die Lötbereiche zur Anbringung des Schirms.Another known embodiment comprises a metal grid, which is also fitted to the substrate and then eingemolded. This variant is also comparatively expensive and requires additional space in the package for the soldering areas for attachment of the screen.
Bei einem weiteren bekannten Verfahren wird ein Metallcoating auf fünf Seiten eines Moldkörpers aufgetragen, nur die Seite mit den Kontaktlands bleibt frei. Diese Ausführung wird durch einen ”Half cut” beim Vereinzeln der LGAs bei der Serienfertigung erzeugt. Hierbei wird durch den Moldkörper bis zum Substrat gesägt, d. h. es wird in der Sägestraße die oberste Metalllage freigelegt. Sodann wird das Coating aufgebracht und kann über das freigelegte Metall an Masse (GND) angebunden werden. Bei diesem Verfahren ändert sich allerdings der Footprint gegenüber einem herkömmlichen LGA.In another known method, a metal coating is applied to five sides of a Moldkörpers, only the side with the Kontaktlands remains free. This design is created by a "half cut" when separating the LGAs in series production. Here is sawed through the mold body to the substrate, d. H. it is exposed in the Sägestraße the top metal layer. Then the coating is applied and can be connected via the exposed metal to ground (GND). However, with this method, the footprint changes compared to a conventional LGA.

Die oben diskutierten Beispiele stellen unterschiedliche Ansätze für die Schirmung von leadless Packages dar. Stets sind hierbei Kontaktierungen des Package nur auf der ungeschirmten, d. h. freiliegenden Unterseite des Package vorgesehen, bspw. über Lands auf der Unterseite eines LGAs. Eine größere Flexibilität bei der Ankontaktierung, so wie dies etwa für MIDs (”Molded Interconnect Devices” bzw. spritzgegossene Schaltungsträger) bekannt ist, die generell dreidimensional aufgebaut und mit entsprechenden Ankontaktierungsmöglichkeiten versehen sind, scheint bei geschirmten leadless Packages nicht möglich zu sein, weil die Schirmung das Package möglichst vollständig umgeben und damit abschirmen muss.The examples discussed above represent different approaches for the shielding of leadless packages. In this case, contacts of the package are always provided only on the unshielded, ie exposed underside of the package, for example over land on the underside of an LGA. A greater flexibility in the Ankontaktierung, as for example for MIDs ("Molded Interconnect Devices" or injection molded circuit board) is known, the generally three-dimensional structure and with corresponding Ankontaktierungsmöglichkeiten Shielded leadless packages do not seem to be possible because the shield must surround the package as completely as possible and thus shield it.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird ein leadless Package mit einem leitenden Coating zur elektrischen Schirmung vorgeschlagen, wobei das Coating derart strukturiert ist, dass durch das Coating auf einer Außenseite des Package mindestens ein elektrischer Kontakt bereitgestellt wird. Bei dem Package kann es sich beispielsweise um ein LGA oder eWLP (”embedded Wafer Level Package”) handeln.According to the invention, a leadless package with a conductive coating for electrical shielding is proposed, wherein the coating is structured in such a way that at least one electrical contact is provided by the coating on an outer side of the package. The package may be, for example, an LGA or eWLP ("embedded wafer level package").
Der Kontakt dient dann der elektrischen Ankontakierung des Package von extern. Das strukturierte Coating kann mindestens einen Kontakt, beispielsweise einen Land eines LGA, auf einer Unterseite des Package kontaktieren. Bei bestimmten Ausführungsformen eines erfindungsgemäßen Package wird hierbei dann der mindestens eine elektrische Kontakt auf einer Seitenfläche des Package bereitgestellt. Hierbei kann das Package zur senkrechten Montage auf einer Leiterplatte vorgesehen sein.The contact then serves to electrically contact the package from the outside. The structured coating may contact at least one contact, for example a land of an LGA, on a bottom of the package. In certain embodiments of a package according to the invention, the at least one electrical contact is then provided on a side surface of the package. Here, the package may be provided for vertical mounting on a printed circuit board.
Zusätzlich oder alternativ kann der mindestens eine elektrische Kontakt auf einer Oberseite des Package bereitgestellt werden. So kann der elektrische Kontakt auf der Oberseite des Package bspw. als bondbares Pad ausgeführt werden. Bei einer Package-on-Package-Komponente mit einem oberen und einem unteren Package kann das untere Package wie oben skizziert mit elektrischen Kontakten auf der Oberseite des Package ausgeführt sein.Additionally or alternatively, the at least one electrical contact may be provided on an upper side of the package. Thus, the electrical contact on the top of the package, for example, be performed as a bondable pad. For a package-on-package component having an upper and a lower package, the lower package may be implemented with electrical contacts on top of the package, as outlined above.
Weiterhin wird eine Verwendung eines erfindungsgemäßen Package bzw. einer Package-on-Package-Komponente wie vorstehend skizziert im Automotive-Bereich vorgeschlagen. Hierbei kann das Package beispielsweise Sensoranwendungen wie etwa Beschleunigungs- oder Lenkratensensoren, oder RF-Anwendungen betreffen.Furthermore, a use of a package according to the invention or a package-on-package component as outlined above in the automotive field is proposed. For example, the package may involve sensor applications such as acceleration or steering rate sensors, or RF applications.
Erfindungsgemäß wird weiterhin ein Verfahren zur Herstellung eines leadless Packgage mit einem leitenden Coating zur elektrischen Schirmung vorgeschlagen. Das Verfahren umfasst einen Schritt, durch den das Coating derart strukturiert wird, dass durch das Coating auf einer Außenseite des Package mindestens ein elektrischer Kontakt bereitgestellt wird. Die Strukturierung kann beispielsweise mittels Laserbearbeitung und/oder Maskierung erzeugt werden.According to the invention, a method is also proposed for producing a leadless package with a conductive coating for electrical shielding. The method comprises a step by which the coating is structured in such a way that at least one electrical contact is provided by the coating on an outer side of the package. The structuring can be produced for example by means of laser processing and / or masking.
Vorteile der ErfindungAdvantages of the invention
Die Erfindung basiert unter anderem auf der Idee, von dem bislang im Stand der Technik vorherrschenden Ansatz einer möglichst vollständigen Abdeckung eines leadless Package durch ein schirmendes Coating zumindest insoweit abzugehen, dass durch von dem Coating gebildete Strukturen Anschlüsse bzw. Ankontaktierungen an beliebigen Stellen der Oberfläche (Außenseite) des Package möglich sind.The invention is based, inter alia, on the idea of departing from the hitherto prevailing approach in the prior art of covering a leadless package as completely as possible by shielding coating in that connections or contact connections at arbitrary locations on the surface are formed by structures formed by the coating. Outside) of the package are possible.
Das Coating dient neben der elektrischen, magnetischen und/oder mechanischen Schirmung somit auch der elektrischen Leitung, beispielsweise von einem Land oder einer sonstigen Kontaktfläche einer eingebetteten Schaltung zu einer durch das Coating gebildeten Kontaktfläche an anderer Stelle der Unterseite, Seitenfläche oder Oberseite des Package. Der Schirmungseffekt des Coating kann hierbei so weitgehend wie erforderlich aufrechterhalten bleiben, indem zur Strukturierung in das Coating entsprechend schmale bzw. dünne Einschnitte, Rillen, Nute oder sonstige Vertiefungen eingebracht werden.The coating thus serves, in addition to the electrical, magnetic and / or mechanical shielding, also the electrical conduction, for example from a land or other contact surface of an embedded circuit to a contact surface formed by the coating elsewhere on the underside, side surface or top side of the package. In this case, the shielding effect of the coating can be maintained as much as necessary by introducing correspondingly narrow or thin cuts, grooves, grooves or other depressions for structuring into the coating.
Durch die erfindungsgemäße Bereitstellung von Umkontaktierungen bzw. Umverdrahtungen auf dem Package wird somit eine Schirmung in Bezug auf EMV-Einstrahlung wie auch gegen Abstrahlung bei RF-Anwendungen aufrechterhalten. Darüber hinaus ergibt sich durch die Erfindung kein zusätzlicher Platzbedarf im Package (z. B. Lötstellen) oder um das Package herum, d. h. das Package-Outline (bspw. Footprint) bleibt gegenüber einem Standard-Package wie etwa einem Standard-IGA unverändert. Damit sind auch standardisierte Handhabung und Weiterverarbeitung, Einbau, etc. eines erfindungsgemäßen Package ohne weiteres möglich.The inventive provision of Umkontaktierungen or rewiring on the package thus a shield with respect to EMC radiation as well as radiation is maintained in RF applications. Moreover, the invention does not result in any additional space requirement in the package (eg solder joints) or around the package, ie. H. the package outline (eg footprint) remains unchanged from a standard package such as a standard IGA. Thus, standardized handling and further processing, installation, etc. of a package according to the invention are readily possible.
Das Einbringen von Strukturen in das Coating kann als zusätzlicher, nachgelagerter Schritt bei einem Standardprozess zur Herstellung von Packages eingeführt werden. Somit entstehen keine weiteren Kosten für die Umstellung des Verfahrens, der Produktionsanlagen, etc.The introduction of structures into the coating can be introduced as an additional, downstream step in a standard process for the production of packages. Thus, there are no additional costs for the conversion of the process, the production facilities, etc.
Zum Schutz vor Umwelteinflüssen kann eine zusätzliche äußere Schutzschicht wie zum Beispiel Silikon aufgetragen werden. Hierbei ist zu beachten, dass statt wie bisher nicht oder nicht nur beispielsweise die Unterseite eines Package zur Kontaktierung freigelassen werden muss (bzw. dort etwa die Lands eines LGAs zur elektrischen Kontaktierung freigelassen werden müssen), sondern dass nunmehr zusätzlich oder alternativ die durch das Coating bereitgestellten Kontaktflächen freizulassen sind.To protect against environmental influences, an additional outer protective layer such as silicone can be applied. It should be noted that instead of as previously not or not only, for example, the underside of a package must be released for contacting (or about the lands of a LGAs must be released for electrical contact), but that now additionally or alternatively by the coating provided contact surfaces are released.
Das erfindungsgemäße Verfahren eröffnet auf einfache Weise eine weit flexiblere Verwendung von leadless Packages als bisher möglich. Beispielsweise können Packages für eine Kontaktierung von der Seite und/oder von oben, für einen senkrechten Aufbau, für eine Verwendung in Package-on-Package-Komponenten etc. einfach bereitgestellt werden. Die Flexibilität erfindungsgemäßer Packages ist damit derjenigen von MIDs vergleichbar.The method according to the invention easily opens up a far more flexible use of leadless packages than hitherto possible. For example, packages for a side and / or top contact, for a vertical structure, for use in package on Package components etc. are easily provided. The flexibility of packages according to the invention is thus comparable to that of MIDs.
Die Erfindung kann für alle Anwendungen verwendet werden, die in Form eines leadless (Mold-)Package implementiert werden und empfindlich auf EMV-Einstrahlung reagieren, beispielsweise für Beschleunigungs- oder Drehratensensoren. Weiterhin kann die Erfindung für Anwendungen eingesetzt werden, die elektromagnetische Störsignale abstrahlen, wie zum Beispiel RF-Bauteile für Anwendungen wie Bluetooth, WiFi, RFID, etc.The invention can be used for all applications that are implemented in the form of a leadless (Mold) Package and sensitive to EMC radiation, for example, for acceleration or rotation rate sensors. Furthermore, the invention can be used for applications that emit electromagnetic interference signals, such as RF components for applications such as Bluetooth, WiFi, RFID, etc.
