22 PCB007 MAGAZINE I MARCH 2022 coating to provide the benefits of copper con- ductivity with electrical isolation when and where it is desired or beneficial. All materials can be procured with the air gap filler applied to one or both sides, which is very important for the elimination of air gaps and voids. e company offers a thermal tape, up to 100 mm thickness, which provides ver- satility and ease of use in special applications or for repairs or modifications. All products are UL V0 rated and all products can be easily cut or punched to a desired shape and size. Solution Selection Considerations Given the relentless trend in electronics toward ever-higher power in an ever-wider array of electronic products, from power mod- ules in PV inverters and wind power controls, to electronic-governed mechanical transmis- sions, AC/DC converters, and high-power LED-based industrial lighting systems, each application may require a different solution to assure that the heat generated by the electron- ics is dissipated as quickly, effectively, and cost- efficiently as possible. A well-balanced thermal management concept will promote and enable a longer service life for the electronic compo- nents and thus higher performance and quality of the electronic end-product. Key factors when selecting the most suitable TIM for a particular application are most fun- damentally the thermal conductivity or thermal resistance, the electrical insulation properties of the material used, while taking into account the different material expansion coefficients to assure that thermal conductivity is maintained, in the X-Y plane and vertically in the Z-axis, when in use to control and mitigate thermally induced forces which might cause undesirable mechanical stresses.
