OhmegaPly RCM (Resistor Conductor Material) is an advanced thin film embedded resistor solution consisting of electrodeposited copper foil with precision-deposited Nickel Phosphorous (NiP) resistive alloy. This embedded resistor copper foil creates a resistive “blank slate” that enables PCB designers to integrate resistors directly into circuit boards, eliminating the need for discrete surface-mount resistor components while improving signal integrity and reducing board space requirements.

OhmegaPly RCM is available through two channels:

• Direct from Quantic Ohmega as thin-film resistor conductor material
• Through global material suppliers as pre-laminated product

The embedded resistive materials are supplied in various foil widths up to 40 inches and multiple sheet resistivity options to enable resistor values from 1 to 50k ohms with predictability and consistency lot-to-lot and sheet-to-sheet.

OhmegaPly embedded resistor PCB technology offers several advantages over discrete SMT resistors:

• Space savings: Reduces PCB footprint by eliminating discrete components
• Improved signal integrity: Minimizes parasitic inductance and capacitance
• Enhanced reliability: Fewer solder joints mean fewer potential failure points
• Better high-frequency performance: Reduced signal path lengths improve RF and mmWave performance
• Cost reduction: Lower assembly costs through reduced component count and simplified manufacturing
• EMI/crosstalk reduction: Integrated resistive elements improve signal routing

OhmegaPly embedded resistive materials enable manufacturing of PCB embedded resistors ranging from 1 to 50,000 ohms. The technology features multiple sheet resistivity options achieved through various NiP alloy thicknesses on Grade 3 copper foil. This wide range supports diverse applications from 5G embedded resistor designs to aerospace embedded resistor systems requiring precise impedance matching.

OhmegaPly resistor conductor material serves mission-critical applications across multiple industries:

• Aerospace & Defense: Military PCB materials, satellite systems, avionics, radar equipment
• 5G & Telecommunications: 5G base stations, mmWave PCB substrate applications, phased array systems
• Automotive: ADAS systems, electric vehicle power management, autonomous driving sensors
• Medical Devices: Biocompatible embedded passive components for diagnostic equipment
• Industrial: High-reliability process control and automation systems
• Space Systems: Radiation-resistant satellite communications and deep space electronics

No. OhmegaPly embedded resistor copper foil is designed for compatibility with standard PCB manufacturing processes. No special licensing or proprietary equipment is required. The material uses conventional subtractive processing methods, making it easy to integrate into existing fabrication workflows while benefiting from the precision plating that ensures uniform deposition.

OhmegaPly is manufactured using Grade 3 copper foil with excellent ductility at elevated temperatures. Common thicknesses include:

• 18 µm (0.5 oz) for high-density applications
• 35 µm (1 oz) for standard designs

The thin film embedded resistor layer features uniform deposition across foil widths up to 40 inches, ensuring consistent resistance values and minimal resistance variation during lamination and normal operation.

OhmegaPly embedded resistor technology exhibits exceptional thermal stability with a low thermal coefficient of resistivity (TCR). The NiP embedded resistor alloy maintains consistent resistance values through multiple thermal cycles and withstands the stresses of PCB lamination without cracking. This makes it ideal for high-temperature applications in aerospace embedded resistor systems and automotive embedded resistor designs where thermal stability is critical.
