Abstract
Description
Die Erfindung betrifft eine Halbleiter-Montagestruktur, und insbesondere eine Halbleiter-Montagestruktur zum Bereistellen einer hohen Wärmeableitungsleistung für Lichtemitterdioden bzw. Leuchtdioden (LED – Light Emitting Diode).The The invention relates to a semiconductor mounting structure, and more particularly a semiconductor mounting structure for providing a high heat dissipation performance for light emitting diodes or light emitting diodes (LED - Light Emitting Diode).
Anwendungen von LED's, die als Lichtquelle für elektronische Konsumartikel dienen, wurden in den letzten Jahren auf Rücklichtmodule bzw. Hintergrundbeleuchtungsmodule, Fahrzeugbeleuchtungen, Projektoren und dergleichen ausgeweitet. Mit wachsenden Anforderungen an den photometrischen Wirkungsgrad, die Produktlebensdauer und die Anwendungsarten ist die Entwicklung von Leistungs-LED's mit hoher Lichtintensität bzw. Beleuchtungsstärke und hohem Wirkungsgrad ein zurzeit intensiv verfolgter Trend.applications of LEDs that as Light source for Electronic consumer goods have been used in recent years on rear light modules or backlight modules, vehicle lights, projectors and the like expanded. With growing demands on the photometric efficiency, product life and application modes is the development of power LEDs with high light intensity or illuminance and high efficiency is a currently intensively pursued trend.
Zum Erhöhen des photometrischen Wirkungsgrades ist der allgemeine Ansatz, den optoelektrischen Umwandlungswirkungsgrad bzw. die LED-Leistung zu erhöhen. Da sich die Eingangsleistung des LED-Chipsatzes konstant erhöht, wird das durch den Wärmestau in der Hochleistungs-LED verursachte Problem schwerwiegender. Folglich leiden der photometrische Wirkungsgrad und die Lebensdauer des Chipsatzes darunter bzw. sinken ab. Andererseits schließen die Faktoren, die die Lichtstromausgabe einer Flächeneinheit eines LED-Gehäuses beeinflussen, die Quantenausbeute, die Chipsatzabmessung (Lichtemissionsfläche), die Eingangsleistung und die Wärmeableitungsfähigkeit des Gehäuses ein. Um einen stabilen photometrischen Wirkungsgrad des Chipsatzes aufrechtzuerhalten, muss die von der Lichtemissionsfläche erzeugte Wärme schnell aus dem Gehäuse heraus abgeleitet werden. Wenn das Gehäuse die Wärme nicht ableiten kann, könnten Leitungsdrähte unterbrochen werden oder das Kunststoffmaterial des Gehäuses könnte infolge der unterschiedlichen Ausdehnungskoeffizienten der Materialbestandteile des Gehäuses verschlechtert werden und die Zuverlässigkeit der LED gefährdet sein. Ferner sinkt bei ansteigender Temperatur der photometrische Wirkungsgrad des Chips signifikant ab. Außerdem wird die Lebensdauer verkürzt und die Wellenlänge und die Flussspannung bzw. Durchlassspannung (Vf) tendieren zum Schwanken.To the Increase of photometric efficiency is the general approach that opto-electric conversion efficiency and the LED power to increase. As the input power of the LED chipset constantly increases, becomes that by the heat accumulation in the high-power LED caused a more serious problem. consequently suffer from the photometric efficiency and the life of the chipset below or below. On the other hand, the factors that make up the luminous flux output close a unit area of an LED housing, the quantum yield, the chipset dimension (light emission area), the Input power and heat dissipation capability of the housing one. To achieve a stable photometric efficiency of the chipset To maintain, the generated by the light emitting surface Heat quickly out of the case be derived. If the case the heat could not derive lead wires could be interrupted or the plastic material of the housing could due to the different expansion coefficients of the material components of the housing deteriorate and the reliability of the LED be at risk. Furthermore, the photometric efficiency decreases with increasing temperature of the chip significantly. Furthermore the service life is shortened and the wavelength and the forward voltage (Vf) tend to Vary.

Raumbeschränkung und eine schlechtere Wärmeableitungsleistung.The heat dissipation of high power LEDs is the most important problem in terms of increasing the photometric efficiency and Product life, and the usual Design of gluing a heat sink to the bottom of the Chipset to realize a heat exchange has many Problems such as changing the assembly process, a space restriction or space limitation and a worse heat dissipation performance.
