EQUIPMENT REQUIRED
Soldering system
Damp sponge
Chisel tip
Vacuum pick-up tool
OPTIONAL EQUIPMENT
Tweezers
MATERIALS
Flux-cored solder
Flux
Cleaner
PROCEDURE
1. Install chisel tip into soldering handpiece.
2. Start with tip temperature of approximately 315°C and change as necessary.
3. Position component ensuring proper lead-to-land alignment. Hold component in
place using the vacuum pick-up tool or tweezers. (See Figure 1.)
4. Apply flux and tack solder opposing corner leads. (See Figure 2.)
5. Apply flux to remaining lead/land areas of the row to be soldered. (See Figure
3.)
6. Clean tip using a damp sponge. (See Figure 4.)
7. Position chisel tip at intersection of lead and land. Apply solder to side of lead/
land area to form proper solder fillet. (See Figure 5.)
8. Repeat step 7 on remaining leads of component.
9. Re-tin chisel tip with solder.
10. Clean, if required, and inspect.
