The edge terminal pad is intended to receive a connection pin (30). It has two tinnable area solder blobs (17, 18) placed overlying each other on opposite faces of a margin of a substrate (10) at locations which are grasped by the claws (33, 34, 35) of the pin (30), with said claws forming the jaws of a resilient clamp. The tinnable area solder blob (17, 18) are notched by grooves (19, 20) at the locations of slide paths followed by the claws (33, 34, 35) while the pin (30) is being put into place. For a pin (30) having three claws with the combined width of all three claws being the same as the width of a terminal pad, one of the pad's tinnable area solder blobs (17) is generally U-shaped, while the other (18) is generally T-shaped. The advantage of the grooves is to restrict the amounts by which the clamp of the pin needs to open and to automatically center the pin on the pad, providing the pin is put into place after the tinnable areas (17, 18) have already been tinned.
