Highly reliable solder and sintering technologies

Metal-metal interconnects are important for electronic packaging & assembly. The session will discuss joining/die attach technologies for highest reliability e.g. silver & copper sintering, leading to a higher package lifetime, as well as “transient liquid phase soldering/bonding” (TLPS/TLPB) for different applications.

Speaker: Dr.-Ing. Matthias Hutter

Electronic packaging and assembly is the basic technology to link the small dimensions of the IC to an interconnecting substrate - usually the Printed Circuit Board / Printed Wiring Board (PCB / PWB) or a Multi-layer Ceramic (MLC) such as "Low Temperature Co-Fired Ceramics" (LTCC).

New applications with their expanding performance and functionality in conjunction with new device technologies are pushing the requirements and innovation for electronic packaging. The metal-metal interconnect can be made by soldering, welding or gluing, all are well-established processes at Fraunhofer IZM. The reliability of electronics will be further pushed to a higher degree in the future. Therefore, reliability standards will see failure rates expressed as failures per billion parts rather than per million parts as is cur-rently the case.

Silver and copper sintering are new die attach technologies which result in a higher life time of the whole power package. Ag and Cu as ductile metals have a high melting point and a very high thermal conductivity. Therefore, especially for a higher performance and higher operating temperatures Ag and Cu sinter joints are very promising.

There is another new joining technology currently under development which is referred to as “transient liquid phase soldering/bonding” (TLPS or TLPB). The idea behind this technology is that the Sn-based solder is transformed in intermetallic phases which have a higher melting temperature than the solder alloy has had before the joining has been carried out. The higher melting point is necessary to withstand higher operating temper-atures or for withstanding subsequent soldering processes during manufacturing.

Hinweise zur Teilnahme:
The expert session series »Advanced Packaging: Simulation, Technology, and Reliability« will give you an exciting insight into hot R&D topics at Fraunhofer IZM and an idea about how you can use our research results and possibilities for your industry or for joint projects together with us.

Participation is free of charge, registration is required. This workshop series aims to address our customers, partners and interested parties from industry, politics and science.

Hilfe

Die Suche / Erweiterte Suche im idw-Archiv
Verknüpfungen

Sie können Suchbegriffe mit und, oder und / oder nicht verknüpfen, z. B. Philo nicht logie.

Klammern

Verknüpfungen können Sie mit Klammern voneinander trennen, z. B. (Philo nicht logie) oder (Psycho und logie).

Wortgruppen

Zusammenhängende Worte werden als Wortgruppe gesucht, wenn Sie sie in Anführungsstriche setzen, z. B. „Bundesrepublik Deutschland“.

Auswahlkriterien

Die Erweiterte Suche können Sie auch nutzen, ohne Suchbegriffe einzugeben. Sie orientiert sich dann an den Kriterien, die Sie ausgewählt haben (z. B. nach dem Land oder dem Sachgebiet).

Haben Sie in einer Kategorie kein Kriterium ausgewählt, wird die gesamte Kategorie durchsucht (z.B. alle Sachgebiete oder alle Länder).
