EQUIPMENT REQUIRED
Soldering system
Soldering iron
Appropriate tip*
MATERIALS
Flux
Cleaner
NOTES
*Choice of the proper tip is based on tools available and the number of bridged
leads. See tips illustrated above.
PROCEDURE
1. Install appropriate tip.
2. Start with the coolest tip temperature possible (approximately 315°C) and change
as necessary. The surface attraction of the solder to the tip must overcome that
of the leads.
3. Clean tip using a damp sponge.
4. Apply flux to the bridged leads. (See Figure 1.)
5. Bring the tip in at a 45° angle in relation to the row of leads. The side of the tip
will make contact with the leads, the toe with the lead and the land.
6. Draw the tip, and the liquid bridge with it, down the row, respreading the solder
across the rest of the leads. (See Figure 2.)
7. Clean, as required, and inspect.
