Note
? The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of
power dissipation may raise the temperature of the solder joint, hence special solder alloys or boardmaterials may be required to maintain
the reliability of the assembly. Specified power rating above 125 °C requires dedicated heat-sink pads, which to a great extend depends on
board materials and design. ?
The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x, or
in publication IPC-7351. They do not guarantee any supposed thermal properties, particularly as these are also strongly influenced by many
other parameters. ?
Still, the given solder pad dimensions will be found adequate for most general applications, e.g. those referring to “standard operation
mode”. Please note however that applications for “power operation mode” or “advanced temperature mode” require special considerations
for the design of solder pads and adjacent conductor areas.
