Description
Gebiet der ErfindungTerritory of invention
Die vorliegende Erfindung bezieht sich auf ein mit Surface Mount Technologie bestückbares optoelektronisches Bauelement.The The present invention relates to a surface mount technology bestückbares optoelectronic component.
Technologischer Hintergrundtechnological background
Heutzutage sind viele verschiedene Arten von mit SM-Technologie bestückbaren optoelektronischen Bauelementen erhältlich. Im allgemeinen können sie in zwei Hauptgruppen unterteilt werden. Die erste Hauptgruppe bezieht sich auf die auf PCBs montierten mit SM-Technologie bestückbaren optoelektronischen Bauelemente. Diese Arten von optoelektronischen Bauelementen werden häufig in weniger anspruchsvollen Anwendungen wie Unterhaltungselektronik eingesetzt. Als Beispiel dienen die 0603 Chip LED-Produkte, die heute erhältlich sind. Ein PCB wird als Grundmaterial verwendet. Metallisierte Bahnen und Lotflecken werden für Chip-Befestigung, Drahtanschluss und Verlöten der Lötstifte bereitgestellt. Dieses optoelektronische Bauelement stellt ein einfaches Mittel zur Verfügung, um kleine Baugrößen und niedrige Höhenprofile zu erzielen. Es hat jedoch seine eigenen Grenzen. Wärmeableitung ist aufgrund der schlechten thermischen Leitfähigkeit des PCB-Materials beschränkt. Außerdem sind die Produkte bei Feuchtigkeit und hohen Temperaturen störanfällig.nowadays are many different types of optoelectronic devices that can be equipped with SM technology Components available. In general, you can they are divided into two main groups. The first main group refers to PCB mounted SM technology optoelectronic devices Components. These types of optoelectronic devices will be often in less demanding applications like consumer electronics used. As an example, the 0603 chip LED products, the available today are. A PCB is used as the base material. Metallised tracks and solder spots are for Chip attachment, wire connection and soldering of the solder pins provided. This Optoelectronic device provides a simple means to small sizes and low height profiles to achieve. However, it has its own limits. Heat dissipation is limited due to the poor thermal conductivity of the PCB material. Besides, they are the products are prone to failure in damp and high temperatures.
Die zweite Gruppe bezieht sich auf mit SM-Technologie bestückbare optoelektronische Bauelemente, die auf Leiterrahmen aufsitzen. Dieser Typ optoelektronischer Bauelemente ist in anspruchsvolleren Anwendungen aus Industrie und Automobilbau weit verbreitet. Ein klassisches Beispiel sind die PLCC2 und PLCC4 Bauteile. Ein Leiterrahmen dient als Grundmaterial zur Bestückung. Kunststoff wird auf den Rahmen eingegossen, um ein Gehäuse für die Bauteile und eine Eintiefung für die Befestigung des Chips bereitzustellen. Anschließend wird klares oder mattes Harz in die Eintiefung gegossen, um Lichtwellenübertragung zu ermöglichen. Dieser Typ optoelektronischer Bauelemente stellt gute Robustheit und eine gute Fähigkeit zur Wärmeableitung bereit. Aufgrund der Einschränkungen bei der Verarbeitung ist jedoch der Grad der möglichen Miniaturisierung begrenzt.The The second group refers to opto-electronic components that can be equipped with SM technology Components that sit on ladder frames. This type optoelectronic Components is used in more demanding industrial and industrial applications Automotive engineering widely used. A classic example is the PLCC2 and PLCC4 components. A ladder frame serves as a base material for Assembly. Plastic is poured onto the frame to form a housing for the components and a recess for to provide the attachment of the chip. Subsequently, will clear or matte resin poured into the recess to light wave transmission to enable. This type of optoelectronic devices provides good ruggedness and a good ability for heat dissipation ready. Due to the limitations however, during processing, the degree of possible miniaturization is limited.
