Special attention must be given to the traces connecting to the metal pads on the board. Trace cracking has been observed during board-level drop and bend tests of this package. This trace cracking usually occurs at the edge of the solder mask opening around the metal pad.
SpletAnd IMS PCBs have thermal conductivity capabilities up to 12 W/ (m. K) and a maximum of 3.2mm metal thickness. But that’s not all. Designers and manufacturers can leverage this increased thermal conductivity and include several heat-dissipating components in IMS PCBs. As a result, you’ll get better compactness overall.
