Notes:
1. Recommended to process PC Boards 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 Dummy or Solder Thief Solder Pad at 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 facilitate soldering it is recommended that ejector latches be installed after the soldering process.
