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 terminals seated on the board. (This may be accomplished by inserting a dummy relay in the socket.) Failure to eliminate float may cause fracture of the solder joint or separation of the copper conductor from the printed circuit board when a relay is inserted in the socket after soldering. .012 (0.30) .310 (7.87) PC board layout (bottom view) for PCB terminal socket .440 (11.18) .160 (4.06) Recommended chassis cutout for solder terminal socket .660 (16.76) .858 (21.79) 1.015 (25.78) 11-2015, Rev. 1115 www.te.com (c) 2012 Tyco Electronics Corporation, a TE Connectivity Ltd. company .410 (10.41) Recommended Chassis Thickness .031 (.79) to .062 (1.57) Datasheets and product specification according to IEC 61810-1 and to be used only together with the `Definitions' section. 14 PLACES .070 DIA.
