Calgreg’s secret was an optimized thermal solution developed with Coolit. Using what-if scenarios, the company analyzed the impact of fin direction, surface area, cross cuts, base thickness, fin thickness, fin height, spacing, etc. Throughout the development, Daat Support provided backup and advice when needed, taking less than 24 hours to evaluate case files and offer recommendations. Daat even modified Coolit to accommodate Calgreg’s needs.
The resulting optimized design was impressive. Calgreg reduced costs by 22%, and in this high volume application, that meant thousands of dollars savings to the customer. Perhaps even more importantly, Calgreg slashed the footprint by 40%. Freeing up board real estate was golden for PCB designers because there was more room to layout traces and less need to route around components.
When the final design tests were run by the customer, Coolit predictions proved to within 4-5%.
