Hi,

Above is a development of PCB thermal analysis tools for a simple PCB has two heating IC structure surface heat distribution analysis results, the main functions of the tool's contribution to the thermal diffusion can be included in the metal layer, you can import and analysis of the two-dimensional wiring diagram of each layer, and then in the PCB design phase have a ballpark knowledge of thermal distribution, to the optimization of PCB structure may,

The thermal boundary condition is to use the heat transfer coefficient of HTC to approximate the effects of the external environment, such as the still air, general convection as well as strong convection, device packaging and add the function of the radiator is included in the corresponding thermal resistance ways to approximate to consider,

, of course, the approximate leading to the accuracy of thermal analysis certainly cannot with commercial fluid calculation software (such as FloTHERM or Icepak) accuracy, but the HTC for approximate calculation of thermal boundary conditions is also widely used in engineering, and the accuracy of the algorithms (i.e., no error in mathematics) has been compared with some fluid calculation software,

Posting the purpose is to want to know you to whether the tool will be interested in, and possible applications, please feel free to comment! Thank you very much!

Before I realized that the more professional commercial software are expensive, as FloTHERM cost is between 60 to 2 million, so I want to some small company PCB thermal analysis service requirements will accept such a single function, at least we can do qualitative analysis of the thermal analysis instruments, or an acceptable PCB thermal analysis technical service,

Qualitative analysis have thermal design requirements demand, would not avail much
