Recommended Mounting Hole Pattern (Shown for mounting side of PC Board) Notes: 1. Recommended to process PC Boards PC Board (thickness .062 [1.57]) through the solder bath such that the connector enters end first (two solder tails at a time). This will help prevent solder bridging. 2. A Solder Thief Solder Pad (Dummy Pad) aat the end of each row is recommended on the bottom or solder side of the PC Board in order to help prevent solder bridging on the end solder tails. The Solder Thiefs are only required on the end of the rows which leave the solder bath last. 3. In order to retain the connector on the PC Board during the assembly and soldering process, it is recommended to have a through hole diameter of .071 + .002 [1.80]. 4. In order to facilitate unmating of the system, it is recommended to use the 3490-2 Pull Tab with the mating .050 % .100 Wiremount Socket. res ect 30 3M Electronic Products Division 6801 River Place Blvd. For technical, sales or ordering information call Austin, TX 78726-9000 800-225-5373
