TacLED-10/TacLED-20
IMS-Based LED Lighting Materials
TacLED-10 and TacLED-20 are
Benefits & Applications :
ceramic-filled thermoset resin composite base materials of
highest thermal conductivity for IMS-based LED lighting
• Isolated Metal Substrate (IMS) for
LED Lighting
applications.
• Highest Thermal Conductivity
Isolated Metal Substrates are typically used to manage thermal
• Thin Dielectric
dissipation (LED color and performance) and to maximise LED
• Thermally Robust Laminate
lifetime.
• Fully SMT Compatible
• Available with Aluminium and
Taconic TacLED-10 and TacLED-20 laminates are
exceptionally robust with “Best in Class” adhesion to metal
Copper Backing
layers. Aluminium and copper backings are available.
TacLED-10 and TacLED-20 dielectrics are very thin (0.0033”
• LED Lighting
[0.085mm]) for low thermal impedance.
Taconic is a leading global manufacturer of bromine-free
PTFE/woven glass base materials mainly for RF-, microwave
and high-speed digital applications - all suitable for lead-free
soldering. All materials are compliant with RoHS and WEEE.
