Logic Package Slims Down

Heralding a breakthrough in ultra-thin leadless packaging, the MicroPakII emerges as the smallest leadless logic package available, measuring 1 mm² with a pad pitch of 0.35 mm. A second package, the SOD882T for RF applications, measures in at 0.6 mm². A special substrate enables a 33% reduction in package size for the MicroPakII over its MicroPak predecessor. With a contact area of 0.298 mm², it also provides a contact-footprint ratio of 30%, said to be nearly double that of most leaded and leadless packages in its class. Reportedly, the MicroPakII also delivers the highest performance in shear and pull tests: 73% better in shear strength and 66% better pull strength than comparable leadless devices.
