Ohmega-Ply® and TCR®

Buried Passives

Ohmega-Ply®, manufactured by Ohmega Technologies, Inc. and TCR®, manufactured by Ticer Technologies, LLC, are thin film resistor-conductor materials. Using standard subtractive printed circuit technology, integral resistors are formed on circuit layers. These resistors can be buried within a multilayer circuit board or used on the board surface.
