TCR is an advanced thin film embedded resistor solution manufactured using precision thin film vapor deposition processes. The technology features nickel chromium (NiCr), nickel chromium aluminum silicon (NCAS),and chromium silicon oxide (CrSiO4) resistive alloys deposited through precision vacuum metallization onto embedded resistor copper foil. This creates superior embedded resistive materials with excellent uniformity across the entire sheet, enabling higher yields and improved resistor tolerances in multilayer organic packages for high-speed, high-density electronic devices.

While both are thin film embedded resistor solutions, TCR uses a different manufacturing process and resistive alloys:

• Manufacturing: TCR employs thin film vapor deposition, while OhmegaPly uses electrodeposition
• Resistive materials: TCR features NiCr and NCAS alloys versus OhmegaPly’s NiP (Nickel Phosphorous)
• Uniformity: TCR’s vacuum metallization ensures uniform ratios of elements in the deposited alloy for minimal resistance variation
• Applications: Both excel in different scenarios, with TCR particularly suited for high-frequency RF PCB embedded resistor applications and multilayer organic packages
• Resistance range: TCR enables resistor values from 10 to 100k ohms versus OhmegaPly’s 1 to 50k range

TCR embedded resistor copper foil enables manufacturing of resistor values from 10 to 100,000 ohms with predictability and consistency lot-to-lot and sheet-to-sheet. The technology features nickel chromium (NiCr), nickel chromium aluminum silicon (NCAS), and chromium silicon oxide (CrSiO4) alloys available in a range of sheet resistivities, providing designers with extensive flexibility for embedded passive components integration across diverse applications.

TCR thin film resistor foil serves demanding applications across multiple high-performance sectors:

The thin and uniform resistive layer ensures excellent final etch tolerances for precise embedded passive components integration.

TCR embedded resistive materials exhibit exceptional thermal stability with a low thermal coefficient of resistivity that minimizes resistance changes during lamination. The resistor conductor material demonstrates minimal resistance change after multiple thermal cycles, making it ideal for applications requiring long-term reliability. The precision vacuum metallization process creates uniform element ratios that withstand stresses without cracking, ensuring consistent performance across temperature extremes in aerospace embedded resistor and automotive embedded resistor applications.

TCR thin film embedded resistor technology has been extensively profiled and tested with a wide variety of resin systems, including:

• Standard substrates: FR-4 and standard epoxy laminates
• High performance materials: Advanced resin systems for demanding applications
• Lead-free compatible: RoHS compliant substrate materials
• Specialty resins: Custom formulations for specific application requirements
• High-frequency laminates: Low-loss materials for 5G pcb materials and mmWave applications
• Flexible substrates: TCR is available on polyimide film based substrates.

This broad compatibility ensures TCR works effectively across diverse multilayer organic packages and high-frequency PCB designs.

TCR embedded resistor copper foil delivers superior performance in RF PCB embedded resistor and high-frequency applications through several key advantages:

• Excellent high-frequency performance: Optimized for RF to millimeter wave spectrum
• Reduced parasitic inductance: Integrated design eliminates inductive reactance of discrete components
• Enhanced signal integrity: Shorter signal paths and better impedance matching
• Lower EMI and crosstalk: Integrated resistive elements reduce electromagnetic interference
• Improved reliability: Fewer SMT solder joints reduce potential failure points
• Thermal dissipation: Exceptional heat management properties benefit both designers and end users

These characteristics make TCR particularly effective for 5G embedded resistor applications, millimeter wave pcb antenna systems, and phased array pcb materials.

TCR’s thin film vapor deposition manufacturing process ensures excellent uniformity of resistor material across the entire sheet, resulting in higher yields and improved resistor tolerances in multilayer organic packages. The precision vacuum metallization creates uniform ratios of elements in the deposited NiCr and NCAS , and CrSiO4 alloys, delivering minimal resistance variation and predictability lot-to-lot and sheet-to-sheet. This uniformity is critical for achieving tight tolerances in demanding applications.

While exact tolerances depend on specific design parameters and processing conditions, TCR’s thin and uniform resistive layer provides superior final etch tolerances. The precision vacuum metallization process and extensive testing under varied lamination conditions enable consistent resistance values with minimal variation. Many applications achieve tolerances of ±15% or better depending on resistor geometry, with even tighter tolerances possible through optimized design and processing.
