More than ten years ago, researchers at Rice University led by materials scientist Boris Yakobson predicted that boron atoms ...

Heterogeneous integration — an umbrella term that covers many different applications and packaging requirements — holds the ...

This paper purposes a method describing the crack propagation of chip on copper substrate solder joints. The chips that were studied are power transistors. They were soldered on copper substrate (NiAu ...

HASL (hot air levelling): micro-cracks appear at the edge of the pad due to thermal stress, exposing the internal copper oxide layer. Failure of solder alloy and flux Solder impurities: aluminium (Al) ...

No Goop Solder Flux - Semi-solid solder wax consistency gives you superior control over application. Simply dip copper electric wires or apply electronic rosin flux to PCB and watch the solder flow!
