Forced convection heat transfer from solder balls on a printed circuit board using the characteristic based split (CBS) scheme

Purpose – To numerically model forced convection heat transfer over arrays of solder balls.Design/methodology/approach – The characteristic based split (CBS) scheme has been used to solve the incompressible Navier‐Stokes equations on unstructured meshes.Findings – The results show an increase in heat transport with increase in Reynolds numbers. A significant change in heat transfer is also noticed with change in angle of attack.Originality/value – The presented results will be useful in designing cooling systems for electronic components.
