An Investigation Into PWB Component-Placement Tradeoffs

M. Pecht, M. Paomer, W. Schenke and R. Porter


The tradeoffs between routing and reliability were measured for various component placements on a multi-layer, primarily digital, printed wiring board (PWB).  The PWB, which was tested, is typical of that used for ultra high reliability radar units in an aerospace environment where conduction cooling is used.  The results are presented.
