QFP-Production Use Socket    Pitch: 0.4 to 1.0mm - Pin Count: 44 to 272
YAMAICHI's IC149-Series is available in more than 27 different formats, from 44 pins to 272 pins. It is designed to fit most of the common semiconductors from various manufacturers. The PC-Board-Layout for this SMT-Socket-Series virtually corresponds to that of the semiconductor. Since the space required for this Socket is the same as the semiconductor itself, there is no need to change the PC-Board-Layout after finishing the experimental stage. Once the Socket is no longer required for trials or testing, it can be removed without the necessity to redesign the PC-Board-Layout. The insertion and fixing of the IC can be easily achieved by bolting the engaging top frame. To secure the Socket before soldering, it is also available with positioning pins.
