Slide Soldering: (Tip Photo - DCS 50 R)

Slide soldering requires the iron tip and terminal relationship to be very consistent. Optimal results

are achieved when the iron tip make contact with both the solder pad and the terminals. Also, the iron

tip should have a slight “OPEN” angle to minimize the potential for solder bridging (photo next page).

During movement, the iron tip should contact all of the leads for the best possible heat transfer.

The sliding speed and feed rate are programmable. Normal sliding speeds range between 3 mm /

second & 5 mm / second.

Iron Tip Programmed Location:

The iron tip position is very important at both the start and finish of a connector row. The photos

below illustrate the proper location for iron tip position.

Solder Feed:

The solder feed height in the photos above is correct. The feed height should be located to the center

of the iron tip (top to bottom) of the tin electroplate area. This ensures that the solder will melt on

contact and wett as evenly as possible. A higher or lower feed height can cause the following issues:

Low Feed Height: The wire may hit the terminals and deflect away from the tip, therefore not melting

High Feed Height: The solder may contact the black plating on the tip causing inconsistent melting and

can actually prevent wetting to the Tin electro-plated area

Some applications do not allow for the tip to slide past the last terminal of a connector such as a plastic

snap-lock etc. or a component in close proximity. In this case, the tip must be programmed to stop on

the last terminal

For some applications, there may be components or plastic parts that prevent the iron tip from sliding

past the last terminal. In this case, you must stop the tip on the last terminal (photo lower right). This

can sometimes cause the solder to “SPIKE” upon removal. It is important to determine the correct

amount of time to leave the tip down to prevent a solder spike from occurring.
