Corpus Christi, Tex. TT electronics IRC Advanced Film Division has developed a high-speed digital termination ball grid array (BGA) package that is designed to prevent signal theft in consumer electronics devices. The CHC series BGA termination network is constructed with no exposed conductors, which makes it difficult to probe after mounting.
The CHC series arrays offer a resistance range from 10 ohms to 10 Kohms with an absolute tolerance to ±1%. The absolute temperature coefficient of resistance (TCR) is ±100 ppm/°C. Element power rating for the array is 100 mW at 70°C with package power ratings to 1.6 W at 70°C. The operating voltage is 25 V and the operating temperature range is 0°C to 125°C. Custom specifications are available. Click the link for the CHC series datasheet.
The CHC ball grid arrays are constructed with all termination balls and circuitry on the bottom side of the device, so there is no way to probe the top side to steal digital content, said the company. In addition, the elimination of vias provides better higher frequency performance, and the single-sided BGA design reduces assembly cost by eliminating the top-side epoxy protection.
The CHC series termination network is constructed with IRC's TaNFilm process, which produces precision tantalum nitride thin-film resistive elements that are immune from corrosion problems common to nichrome resistors in humid environments. Applications include set-top boxes, digital TVs, personal video recorders, DVD players and other digital consumer electronics.
Pricing for the CHC series devices is $1.00 each in quantities of 10,000. Delivery is from stock to ten weeks.
