C-MAC reduces cost of stacked module potting compound by 50 percent using Flotherm.
C-MAC MicroTechnology (Great Yarmouth, UK) used Flomerics' (Marlborough, MA) Flotherm thermal simulation software to determine that the thermal requirements of a stacked module could be met with a potting compound that cost only half the amount of the default choice.
C-MAC, an electronics design and manufacturing company, recently developed a stacked module for a critical defense application. Prior to building prototypes, C-MAC engineers performed thermal simulation on the initial concept design and discovered that junction temperatures on the module ranged up to 125 degrees C, well above the 100 degrees C maximum.
C-MAC realized it needed a potting compound to reduce thermal resistance and wanted to select the least expensive formulation that would meet the thermal requirements of the application. Compound type: simulated junction temperature — Standard (110 degrees C); Enhanced (85 degrees C); and Best (75 degrees C).
