SinkPAD Corporation’s new SinkPADTM aluminum PCB technology are a complete and effective solution to the challenges faced by the solid state lighting industry, specifically those with aluminum LED PCB applications. SinkPADTM conducts heat out of the LED system (LED conduction cooling) by enabling a direct thermal path between the LED and surrounding atmosphere. The LED thermal … [Read more...]
New PCB Heater Assemblies for Low Temperature Applications
Spectrum Sensors & Controls has developed a new series of printed circuit board (PCB) heater assemblies for use in applications where sensitive electronics need to operate at very cold temperatures, or where electronics need a temperature-controlled environment. Some electronics have a limited operating temperature range, but Spectrum’s heater assemblies allow low … [Read more...]
Thermally Conductive Printed Circuit Board Substrate
Laird Technologies, Inc. recently announced the release of its enhanced Tlam™ SS LLD for use as a thermally conductive printed circuit board (PCB) substrate. The Tlam SS LLD is a versatile, thermally enhanced PCB substrate system specifically designed for heat dissipation in bright and ultra-bright LED module applications. The thermally conductive PCB substrate provides 8-10 … [Read more...]
Vibration Analysis For Electronic Equipment
This topic is rather esoteric and usually an afterthought in commercial and industrial applications. In military and defense electronics, it is one of the major drivers for design and product architecture early on in the design cycle with specific targets/budgets. As with junction temperature requirements in a thermal design, there are structural dynamic issues that need to be … [Read more...]
Characterizing a package on a populated printed circuit board
This column has emphasized methods of analyzing packages in the JEDEC-standard test environment. A thermal metric that lends itself to analyses of system applications is the junction-to-board thermal characterization parameter, JB. If one knows the board temperature (TB), then the junction temperature (TJ) can be determined by a simple application of the following formula: TJ … [Read more...]
