PCIM: 650V 40A IGBT

ST Microelectronics has announced a 650V 40A IGBT in a TO-247 package, the first of what will become its previously-announced HB2 series. “The HB2 series has outstanding conduction performance thanks to a VCEsat of 1.55V,” said ST. “At the same time, dynamic behaviour is enhanced due to reduced gate charge that enables fast switching at ...

Copper particles displace silver for inks and bonding

Japanese scientists are proposing a copper alternative to sintered silver die-attach and conductive ink. Sintering – the process of pressing powders together to form solids – can occur at far lower temperatures than melting the same powder into a mould. However copper, for all of its excellent electrical and thermal properties, does not easily form ...
