The new Tyco Electronics Low Profile DDR2
connector is designed for the main memory
requirements on the AdvancedTCA carrier
boards. Developed for use with a new
VLP (Very Low Profile) module from Micron
Technology, this connector meets the
AdvancedTCA height limitations on the
carrier board.
In addition, this connector offers a new
ejector design that allows airflow to reach
the memory module DRAMs for effective
cooling.
