DESIGN OF HALF SPLIT /BRANCH FLEXI-RIGID PCB

摘要

? Branching the PCB in flexible area in lateral direction is new way of design in combination of rigid and flexible multi boa rds together. ? This provisioned easy connectivity of all modules in a LRU. ? It is a challenging task to design PCB with half split flexi board from a rigid board. ? Multipoint connectivity for different modules are achieved through Cables looms Replaced by flexible PCBs. ? Connecting in series method is normal way of flexi board design parallel connection to two PCBs (split) in lateral way is achieved through innovative PCB design method. ? Component placement and routing of the connections in multiple rigid and flexible one over another achieved through creative way of design and explored new method of manufacturing. ? Crosstalk and coupling enhanced through proper layer stacking and ground shielding/providing ground mesh in top and bottom of the PCB. ? Reliability of connections ensured in flexi board and manufacturing method. ? Critical supply lines and Bus lines /impedance control lines achieved through proper copper thickness and layer stacking.
