I will socket the chips because with lack of experience, I have no doubt that many chips will be sacrificed before this actually works.
I found a pattern for the PLCC socket so at this point I should be able to add the HV5522 to the Diptrace library without problems. I need three chips for this project, which will use seven nixies.
