ABSTRACT:
An apparatus for changing the contact pitch of a contact array of a first density to a contact array of a second density includes first and second pluralities of cards, with the cards having a first row of contacts disposed along one edge thereof having a mutual spacing therebetween equal to the pitch of one of the arrays and a second row of contacts along another edge having a mutual spacing equal to the pitch of the other one of the arrays. The cards in their respective pluralities are arranged parallel with one another with the two pluralities of cards facing each other and disposed at a right angle to each other. The first rows of contacts of the first plurality of cards provide a contact array having the first density while the second rows of contacts of the second plurality of cards define a contact array of the second density.
