Buried resistor is an advanced technology to replace discrete resistors with thin and planar metal resistors laminated within multilayer printed circuit boards. This technology offers the best solution for high density circuit board used in high speed and high frequency application since it can save the space previously occupied by discrete resistors. The space saved by buried resistors can be used for additional components or trace routing. This buried resistor technology is also effectively applied to very small sized printed circuit boards in high density circuitry
