Development and process control for rigid/flex, multilayer printed wiring boards
Technical Report
·
OSTI ID:6408960
Rigid/flex multilayers require certain unique processing parameters not common to conventional printed wiring products: special machining of windows, the use of no-flow prepreg adhesives, plasma etching of nonhomogeneous material compositions, and more stringent plating controls. Performance of these products can be predicted by modeling studies and verified by physical testing. Thermophysical characteristics are described as well as the establishment of rigid/flex capabilities in a development laboratory. The actual fabrication processing steps are also described for high-reliability, six-layer rigid/flex boards whose two center layers are flexible circuitry.
