Title: Circuit board with self-locking terminals

Abstract: The present invention provides an apertured circuit board having self-locking terminals which partially cover at least some of the apertures. The terminals, which are integral extensions of the circuit pathways, each include a pair of inwardly disposed generally L-shaped fingers. The terminals are adhesively anchored to the circuit board at the terminal peripheries and are covered in part by a dielectric overlay. The latter also provides environmental protection and electrical insulation to the circuit conductive pathways. The circuit board and integral sockets may be formed by photoimaging and chemical milling techniques.
