ABSTRACT:
A printed circuit board for connecting, in n different ways, connection pins of an integrated circuit mounted in a dual-in-line (DIL) package to printed circuitry on the printed circuit board, where n is an integer .gtoreq.2. The printed circuit board comprises contact holes which are electrically connected to the printed circuitry and are each suitable for receiving a connection pin of the DIL package. To avoid the use of so-called jumper blocks for the different ways of connection, the contact holes form a matrix of p columns and q rows, with p being at least equal to the number of connection pins on a long side of the DIL package, q being at least equal to 2n, and the distance between successive rows of contact holes being such that n-1 rows of free contact holes are located between the rows of connection pins on the opposite long sides of the DIL package when these rows of connection pins have been mounted in two rows of contact holes. The contact holes are preferably located in an IC base, so that the desired connection can be chosen by placing the package in this base in one of the n possible ways.
