Manufactur-ers who know that DFM issues like acid traps, slivers and starved thermal pad connections can decrease manufactur-. Thermal Resistance and Heat Dissipation of LED PCB with Thermal Vias. Component placement, cooling strategies, or "worst case" conditions can be quickly evaluated using this software. Besides being very simple to learn, this software provides wide engineering capabilities with intuitive user interface. established in 2007 has become one of the Best Engineering Solutions Partner in the PCB Design Services. i made simple geometry today, but the problem I am facing is what to do with the geometry, how to have the thermal analysis of it.
