... desperate needs to overcome real estate constraints whilst trying to maximise component configurations. As a result new alternatives such as buried vias, blind vias | PRINTED WIRING BOARDS PROTOTYPE | or a mixture of both have been successfully utilised by designers trying to maximise board real estate by increasing the density of lines and pads. | PRINTED WIRING BOARDS PROTOTYPE | However, many manufacturing and design issues must be addressed before adventuring down this path. Due to the many additional oper- ations, the cost of a | PRINTED WIRING BOARDS PROTOTYPE | blind or buried via board is significantly higher than that of a multilayer of the same layer count. | BURIED VIAS | A buried via | PRINTED WIRING BOARDS PROTOTYPE | is a copper-plated hole, imbedded in the board, that interconnects two internal layers. The buried via process starts by drilling holes on thin core laminate. | PRINTED WIRING BOARDS PROTOTYPE | These cores are then metallised, imaged and etched before being laminated. Individual manufactuer´s method of fabricating multilayer boards mast be understood before designing bboards with | PRINTED WIRING BOARDS PROTOTYPE | buried vias. Designed an manufactures layer ...
