PCB电子线路板热分析ANSYS建模In this article, the ANSYS modeling problem of PCB thermal reliability analysis is studied. By ANSYS analysis, two conclusions can be drawn: (1) Copper lead on PCB has significant thermal transmission effect, so it should not be omitted in modeling. (2) Component ...
A modeling methodology is proposed for the thermal analysis of the PCB structure based on integrating both the FVM-based numerical solution and the Fourier-series-based analytical solution of temperature. The heat spreading through tracks and the vertical heat transfer through vias are taken into ...

PCB thermal analysis tools are a necessity for modern board functionality and reliability. Unlike some other forms of analysis, failure to incorporate thermal tools into a design may still result in a producible board that passes testing, but its outlook on reducing the effects of heat falls dram...
This paper focuses on the thermal analysis of front-end AC/DC converter in an EV onboard charger. The converter topology chosen is phase shifted boost PFC converter and the performance of the converter is analysed using wide band gap semiconductor devices. The thermal impact on the semiconductor...
Finite element analysis (FEA) was used to model the thermally-induced warpage of a printed-circuit-board (PCB) assembly having an array of pin-through-hole (PTH) connectors during a dual-wave soldering process. The estimates of board warpage were compared with experimental measurements, and it ...
This paper provides a comprehensive reliability and thermal analysis of a typical multi-layer printed wire board (PWB) wirability design. Based on some typical values of modern PWB designs, numerical solutions are provided for the junction temperature, failure rate, reliability, electrical delay and ...
