Electronic Interconnect Introduces a Novel Method for Removing High Amounts of Thermal Energy

Direct Thermal Exchange (DTE) is a cutting-edge PCB construction methodology for highly-efficient heat removal or thermal dissipation. As the name implies, it is a “direct” thermal transfer method used when high amounts of thermal energy must be removed quickly and consistently from a heat-generating device. DTE was developed at Electronic Interconnect primarily to address thermal problems posed by the development of high-power LEDs with demanding thermal performance, although it can be used in many other applications.

Direct Thermal Exchange (DTE) is a cutting-edge PCB construction methodology for highly-efficient heat removal or thermal dissipation. As the name implies, it is a “direct” thermal transfer method used when high amounts of thermal energy must be removed quickly and consistently from a heat-generating device. DTE was developed at Electronic Interconnect primarily to address thermal problems posed by the development of high-power LEDs with demanding thermal performance, although it can be used in many other applications.

DTE design creates a direct thermal path conduction capability and reduces LED junction temperature far more efficiently when compared to traditional FR-4, metal core or aluminum printed circuit board constructions. Lower junction temperature extends LED life, improves LED brightness (higher lumens per LED), improves product reliability and minimizes overall dollar-per-lumen operating cost, according to Philips, “Understanding Power LED Lifetime Analysis,” white paper.

Pratish Patel, president and CEO at Electronic Interconnect Inc. says, “DTE is an important enabling technology for LED arrays, especially those intended for outdoor lighting and emergency vehicles, where heat dissipation is a concern as the technology of high-power LEDs advances.”

Minimizing LED junction temperature. LEDs radiate minimal heat into the space around the source. Consequently, all the heat generated by the LEDs must be conducted away from the source by physical means, i.e., a conduction path. If heat generated by the LEDs is not conducted away, and excessive heat builds in the LED, the LED cannot function properly and can be permanently damaged. The light emitted by it can change to an unacceptable color, and its working life can be seriously curtailed. Thus, designers and specifiers should ensure that the PCB material and type selected for the LED application offers the least thermal resistance in order to avoid LED “thermal runaway.” The DTE PCB approach eliminates use of a dielectric material completely from a conduction thermal path, allowing direct thermal exchange. DTE circuit boards are available in various thicknesses, as well as base metal types.

Pratish Patel, president and CEO at Electronic Interconnect Inc. has published an article about the new DTE PCB construction methodology in the January 2013 issue of "Printed Circuit Design & Fab" magazine.
