TYPICAL CUSTOMER QUESTIONS What is the Ohmega-Ply? resistive material made of? Ohmega-Ply? is a true thin-film, Nickel-Phosphorous (NiP) alloy. In the manufacturing process, about 0.1 to 0.4 microns of the alloy is electro-deposited onto the rough, or tooth side, of electrodeposited copper foil. What types of copper is it available on? The copper foil is standard electrodeposited copper. Both single and double treat coppers of 0.5 oz, 1 oz and 2 oz weights are available. What types of dielectric are available? The Ohmega-Ply? product is sold either in an unlaminated form (Ohmega-Ply? RCM, or Resistor-Conductor Material), or laminate form. Ohmega Technologies subcontracts the lamination to the independent laminators. Ohmega-Ply? is therefore available on most dielectric materials now offered in the industry. What is Ohms per Square? Ohms per square is a dimensionless square area of resistive material, the length and width of the res
