CERAMIC PRINTED CIRCUIT BOARD AND AN INK JET PRINT HEAD ASSEMBLY USING THE SAME TO IMPROVE SIGNAL QUALIFICATION WITHOUT AN ADDITIONAL DEVICE

摘要

PURPOSE: A ceramic printed circuit board and an ink jet print head assembly using the same is provided to prevent the degradation of the signal qualification by mounting a longitudinal end resistance body in the minimum distance with a final reception end.;CONSTITUTION: A ceramic printed circuit board comprises terminals(31,32), circuit patterns(33,34) and a longitudinal end resistance body(35). The terminal receives an electric signal from outside. The circuit pattern is connected to a plurality of terminals. The circuit pattern transmits the electric signal. The longitudinal end resistance body with the fixed height is located between the circuit patterns. The longitudinal end resistance body is built in a plurality of layers(L1-Ln). The final reception end which finally receives the electric signal is included in the upper side of a plurality of layers.;COPYRIGHT KIPO 2010
