SOLDER PAD DIMENSIONS

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 board materials may be required to maintain

the reliability of the assembly.

Specified power rating above 125 °C requires dedicated heat-sink pads, which depend on board materials.

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” require special considerations for the design of solder pads and

adjacent conductor areas.
