CUI Devices’ Thermal Management Group has expanded its heat sink product portfolio with the addition of BGA heat sinks. The HSB family, designed for ball grid array (BGA) devices, supports a range of sizes from 8.5 × 8.5 mm up to 60 × 60 mm with profiles from 6 mm up to 25 mm.
The BGA heat sinks are made from aluminum with a black anodized finish and offer adhesive mounting styles. Thermal resistances measured at 75°C ΔT in natural convection environments range from 6.41 to 39.1°C/W, while power dissipation ratings range from 1.92 up to 11.69 W at 75°C ΔT in natural convection. Performance curves for full thermal resistance are available in each of the individual part number datasheets.
Prices for the HSB heat sinks start at $0.42 each in quantities of 1,000 through distribution. Lead times is from stock to eight weeks. More information on thermal management including tools such as heat sink and thermal conversion calculators can be found at the company’s resource library.
