Ventec PCB material incorporates embedded resistor-foil layer for handling high-frequencies

For enhanced high-speed signal-handling performance required by the world’s most demanding high-frequency printed circuit board applications, Ventec International Group has launched a laminate option to its tec-speed 20.0 glass-reinforced hydrocarbon and ceramic laminate cladded with thin-film resistor material from Ticer.

Ventec’s tec-speed 20.0 material, which combines unrivaled high-frequency performance (Dk 3.00-3.48/Df 0.0027-0.0037), superior loss characteristics and highest reliability, is now available cladded with Ticer TCR© NiCr thin-film resistor foil as a service option. Essentially being inductor-free, the addition of the resistive material technology offers an enhanced material solution for some of today’s high-speed, low-loss, high-frequency applications where absolute performance and reliability are essential. These include aerospace & defense, radar, control circuits, sensor technologies, wireless communications, MEMS microphones/sensors/motors and medical diagnostic type applications.

Driven by the demand for reduction of dimensions and manufacturing costs of these types of devices, multi-layer technologies are one of the solutions that offer an increase in component packaging density. By adding the resistive foil layer in between the substrate and the copper layer, resistors can be embedded inside of PCB’s after the lamination process.

Consequently, additional efficiencies the shorter distance between the embedded passives and active components achieves additional efficiencies that result in better signal transmission, less cross talk and improved electrical signal performance at high frequencies through lower loss and noise. In addition, material cost reduction, yield improvement, defect reduction and ultimately an optimized production cycle time and time to market can be achieved.

The embedded resistor foil layer material option named tec-speed 20.0 VT-870 H348 TCR is available in Hoz and 1oz thick foil with resistivity values of 25, 50 and 100 Ω/sq.

“The high-speed signal-handling performance of our latest VT-870 H348 TCR material cladded with Ticers’ unique technology provides additional efficiencies for Ventec’s tec-speed 20.0 material,” noted Mark Goodwin, COO Europe & America. “It allows us to offer our customers an even greater choice of the best in high-quality, high-performance and reliable base material technology – all of course supported by our fast and efficient global delivery promise through our fully controlled global supply chain and dependable technical support.”
