Printable resistors in LTCC systems

Printable resistors in LTCC technology offer some advantages in comparison with discrete components, such as the increased power handling and reliability. As the size of chip resistors decreases, also the size of printed resistors has to be reduced. For optimizing high-frequency performance the size, i.e. width in particular, has to match the width of the transmission lines. In this study the effects of different resistor dimensions and processing parameters have been analyzed. The experimental work has been made with Du Pont 951 and Ferro A6-S LTCC systems. By optimizing the processing, the resistance tolerances smaller than ±12% were achieved.
