METHODS OF INTERCONNECTION - RF Cafe

 

Three methods of interconnecting circuitry in multilayer printed circuit boards are the CLEARANCE-HOLE, the PLATED-THROUGH-HOLE, and LAYER BUILD-UP.
 
MODULAR ASSEMBLIES were devised to achieve high circuit density. Modular assemblies have progressed from CORDWOOD MODULES through MICROMODULES. Micromodules consist of film components and discrete components to integrated and hybrid circuitry.
 
ENVIRONMENTAL FACTORS to be considered are temperature, humidity, shock, vibration, and rf interference.

ENVIRONMENTAL FACTORS - RF Cafe

 

ELECTRICAL FACTORS are overcome by using shielding and ground planes and by careful placement of components.
