Abstract

Typical leadless chip carrier sockets are large and require much more circuit area than dual in-line sockets. An adapter socket shown in Figure 1 allows a leadless chip carrier to be used with a dual in- line socket.

A LEADLESS CHIP CARRIER TO DUAL IN-LINE ADAPTER SOCKET

By Alan Kissinger

   Typical leadless chip carrier sockets are large and require much more circuit area than dual in-line sockets. An adapter socket shown in Figure 1 allows a leadless chip carrier to be used with a dual in- line socket.

The leadless chip carrier to dual in-line adapter socket of Figure 1 is designed to connect terminals of the leadless chip carrier device with pins which plug into commonly used dual in-line sockets.

   Loading of the leadless chip carrier is accomplished by applying a force along the bottom sides of Part A and Part B, thereby enlarging the opening at the top of the adapter socket and allowing a chip carrier to be inserted into the adapter socket. The chip carrier adapter socket can then be inserted into a dual in-line socket as shown in Figure 1.

   A chip carrier can be removed from the adapter socket by first removing the chip carrier from the dual in-line socket. The leadless chip carrier will easily fall out of the socket when the adapter socket is inverted and a small force is applied along both sides to open the top of the socket.

A perspective view of the leadless chip carrier adapter socket is shown in Figure 2.
