Double-Sided Tapes (DST)

Double-Sided Tapes (DST) are a common material generally used on small heatsinks. They vary in thickness and can be used to fill voids between the device and the heatsink.

 

The DST also has mechanical strength to hold the heatsink in place. Some DST materials are better suited for plastic devices vs. metal, so make sure the final use is well understood.
