CONNECTION VALIDATION OPERATION
•
Pick a tip that maximizes contact area between the solder joint and tip. Maximizing contact area gives the most
efficient heat transfer, producing high quality solder joints quickly.
•
Pick a tip that allows good access to the solder joint. Shorter tip lengths allow quicker response. Longer or angled
tips may be needed for soldering densely populated boards.
•
Pick the lowest temperature cartridge that will accomplish the task. This minimizes the potential for thermal
.

Enable CV through the Setup Screen
The system may flash the green and red lights and an optional beep may sound when the tip is cleaned or
in the work stand. This is normal and does not signal the start of a solder event.
1. Remove the hand-piece from the work stand. Clean
your tip using a sulfur-free sponge & de-ionized water or
Metcal's brass pad.
2. Place the tip in contact with the land and lead to be
soldered. This starts the heat flowing to the connection
area. It may be necessary to apply a small amount of
solder to start the transfer.
If the system does not signal the start of the solder event, your tip selection is too large for the load or
thermal contact with the load to be soldered is insufficient. This may be prevalent with small, fine tip
geometries with minimal surface area.
4. The thermal bridge is formed by
touching the solder to the same junction,
then moving the solder wire to the
opposite side of the land. This causes the
liquid solder to move toward the heat
source to complete the solder joint.
5. Wait for the CV system
to signal the end of the
solder event.
Wait for the LED light to extinguish before starting the next solder joint.
Or
Success
•
An immediate red light after solder event detection indicates the tip is
improperly sized to the joint.
•
A red light after approximately 8 seconds indicates too small of a tip
or too low of a temperature was selected.
3. The system will
signal the start of the
solder event with a
quick flash of the
green and red LEDs.
6. Promptly remove the
soldering tip from the
solder joint
