This permits them to align with holes in the circuit board and with the relay terminals. During the mounting and soldering of the socket, vertical float should be eliminated and the .068 terminals seated on the board. (This may be accomplished by inserting a dummy relay in (1.73) .183 the socket.) Failure to eliminate float may cause fracture of the solder joint or separation of (4.65) the copper conductor from the printed circuit board when a relay is inserted in the socket after soldering. 1.150 (29.21) .012 (0.30) .310 (7.87) 1.07 .850 PC board layout (bottom view) for PCB terminal socket (21.59) (2.72) .440 (11.18) .160 (4.06) Recommended chassis cutout for solder terminal socket .410 (10.41) .660 (16.76) .858 (21.79) 14 .175 PLACES (4.45) .070 DIA.
