IRC Introduces Precision Ceramic BGA Packaged Resistor Networks

April 25, 2007 by Jeff Shepard

IRC Inc. announced that it has developed a series of precision resistor networks in a ceramic ball grid array package. Designated the CHC-Precision Series, the BGA package features all circuits on the bottom side of the device in order to eliminate wrap-around terminations.

According to Jerry Seams, New Business Development and Applications Engineer for IRC Advanced Film Division, the design of the CHC-Precision BGA package provides customers with several advantages. "The single-sided monolithic design allows us to eliminate parasitic effects due to wrap-around terminations. Additionally, with a high precision device such as this, it is essential to be able to wash under the component in order to eliminate the detrimental shunting effects of uncleaned assembly process residues."

The CHC-Precision Series BGA Series networks are suitable for industrial applications, process control and monitoring, medical equipment, instrumentation and metering. They are available in 8- and 16-pad packages. The ball grid array features a resistance range from 10 to 100KΩ, with a maximum working voltage of 50V. The device features TCR tracking to ±5ppm/°C, ratio tolerances to ±0.05%, absolute tolerances to ±0.1%, and absolute TCRs to ±25ppm/°C. Operating temperature range is -55 to + 150°C. IRC will also produce devices outside these specifications to meet customer requirements.

The CHC-Precision Series ball grid array utilizes IRC’s patented TaNFilm® (tantalum nitride) technology. IRC’s TaNFilm process produces precision tantalum nitride thin film resistive elements that are immune from corrosion problems in humid environments. The self-passivating properties of tantalum nitride are said to result in a more stable, reliable resistive device. This process allows IRC to manufacture custom circuit configurations and multiple resistance values without compromising tight tolerance or tracking characteristics.

Pricing for the CHC-Precision Series BGA package is $1.00 each in quantities of 10K pieces. Lead time is from stock to 10 weeks ARO.
