Fundamental Aspects of Brazing and Soldering

Brazing & Soldering Today

Brazed components play an essential role in consistent joining techniques. The brazing process is characterized by low process temperatures and fast processing times, compared to welding techniques. Beside the resulting low manufacturing costs, brazing can join dissimilar materials, e.g. metals and ceramics. Consequently, brazing provides potential for many industrial applications like the prod...

Brazing & Soldering Today

JULY 2012 50 High-temperature solder alloys are extensively used in dieattach, power semiconductor, and optical device packaging, flip-chip packaging, etc. Current industry standard solders for these applications are mainly high-lead solders (90–97 wt-% Pb) and gold-based eutectic solder alloys such as the 80Au20Sn solder. The die-attach process involves connecting the silicon die or chips to a...

Aspects of Fundamental Muon Physics

The muon is a second generation fundamental fermion which belongs together with the electron and tauon to the group of charged leptons. To our present knowledge it behaves as a point-like particle which is subject to electromagnetic, weak and gravitation interactions. It diiers from electron and tauon in its behaviour and properties solely through its mass which is called lepton universality. T...
