... array of heated modules mounted on a printed circuit board (PCB) forming one of the walls of a vertical channel is presented. Numerical investigation involved turbulent flow analysis based on a realizable k − ε model. Experimental efforts involved development of a test rig and use of state-of-the-art...

...Kun-Nan Chen In the design of printed circuit boards (PCBs), it is preferable to increase their fundamental frequency so as to reduce the effects of the dynamic loading on them. The dynamic characteristics of a PCB carrying various electronic components and modules are most significantly affected...
