Thermal Tape
Thermal Tape Thinnest Heat Sinks

Siloxane-Free & Halogen-Free
Therm-A-Sheet is a thermally conductive
adhesive sheet which is made of
aluminum foil or thermally conductive
compound. Only applying between hot
electronic components and heat sink,
excellent heat-spreading effect is
available.

Use
For thermal junction of micro device
For thermal junction of power device

Features  
1. Excellent thermal conductivity
Aluminum foil or thermally conductive
compound offers the excellent thermal
conductivity. It keeps stable thermal
conductivity even after used for a long
time.  		2. Easy operation
The sheet is soft and easy to be applied
by peeling off the separator and pressing
to the substrate.

Phase Change Type
Thermally Conductive Sheet

Therm-A-Sheet, PC series is a phase
change type thermally conductive sheet.
The sheet is easily applied by peeling
off the separator and pressing it onto
the substrate and provide adhesion.
Only applying between hot electronic
components and heat sink, excellent
heat-spreading effect is available.
Advantage  
Low Thermal Resistance.
Thixotropic and Won't flow from
interface area.
Thermoplastic reversible
adhesive bond.
Non-halogen and Non-siloxane
:made from halogen-free and
siloxane-free materials.
 
   
The terminal obstacle of silicone rubber

Silicone rubber carries out the polymerization of the siloxane of a low molecular weight by
the ring- opening-reaction in a catalyst, and is obtained, as shown in the following figure.
In this case, all low molecular weight siloxanes do not react and it remains a little. The
evaporated siloxane adheres to a terminal and it is considered to change with oxidization
by the heat of a spark to a silica (SiO2) insulation layer.
