ic packages hi i am looking for some help in choosing a package for a high speed silicon adc mhz currently being fabricated this is a phd research project and i have to test the chip at speed on a pcb i expect to have roughly packaged circuits and will do dc low speed and high speed testing using different set ups for the test chip i know for sure that a dip will not work the long lead lines have too high an inductance getting a custom made package is too expensive so i am trying to choose between a flatpak and a leadless chip carrier the flatpack would be hard to test since it has to be soldered on to the test setup and i would spend loads of time soldering as i kept changing the test chip the leadless chip carrier sockets also have long lead lines and may not work at high speeds does anyone out there have experience knowledge of this field i would greatly appreciate help any ideas names of companies manufacturing holders sockets packages would help p s the multi layer fancy gaas packages seem like a bit of overkill seema varma
