Thermally Conductive PCB

Thermally Conductive PCB

Tlam SS HTD Series

Thermally Conductive Printed Circuit Board Substrate
Tlam SS HTD is a thermally conductive PCB substrate. The construction consists of a copper circuit layer bonded to an aluminum or copper base plate with 150 C rated Tlam HTD dielectric. Tlam SS HTD laminate is processed through standard FR4 print and etch operations.

Tlam SS HTD products have 6-8 times better thermal conductivity than FR4–key to keeping components cool. The Tlam SS HTD boards are run through standard pick and place SMT and manual wire bond processes.

Tlam SS HTD is designed for use in high temperature and/or high-voltage applications typically found in industrial motor drives and automotive motor controls.

Standard constructions are made with 1 and 2 ounce copper and 0.040 (1mm) and 0.062 (1.6mm) inch thick aluminum. Custom construction of heavier weight circuit copper and thicker aluminum and copper base plates are also available.

• Lower thermal resistance

• UL® 746 B RTI of 150°C

• High withstand voltage >6000 VDC

• RoHS compliant

• Environmentally green

• Significantly reduces power device temperature

• Lead free solder compatible

Additional Product Description
All properties are typical @ 25°C, unless otherwise specified.
For design engineer guidance only, observed performance varies in application. Engineers are reminded to test the material in application.
Peel strength is measured with 1oz Cu weight.
All properties are based on nominal thickness. The layout and process may require thicker starting Tpreg to meet nominal laminated thickness.
Applications • Automotive – LV under hood and EV motor drives
• 120-480VAC commercial and industrial motor drives, UPS and welders
• Power Supplies – AC/DC and DC/DC for telecom and commercial products
