Summary of change:
'''Potting compond''' The Wacker ELASTOSIL® RT 675 A/B potting compound has amazing heat transfer properties: http://www.wacker.com/ http://www.wacker.com/internet/webcache/de_DE/PTM/TM/Elastosil/Elastosil_RT_Addition/ELASTOSIL_RT_675.pdf Thermal conductivity: 1,2 W/m×K. Some comparisons: Copper: 401W/m*K. Pure aluminium: 237W/m*K. Normal aluminium: 100W/m*K. Air: 0,0025W/m*K This silicone compound is in other words 480 times better than air or 100 times worse than solid aluminium. We may want to use this as a partial fill for the new products with lots of SMD switches, it will make heat transfer much simpler. It is sold by Elfa in sweden, article number 80-852-84. 1100SEK + VAT for 2kg!
