Figure 1: Place component and
check alignment.
|
| 1.
|
Add liquid flux to the corner pads. |
| |
| 2. |
Place the component in position and hold it
steady. The leads must be aligned with the pads.
On large components this is best done by aligning
the leads on opposite corners. (See Figure 1).
|
| |
|
| 3. |
Place the soldering iron tip at the junction
between the pad and component lead at one of
the corners. Apply additional solder as needed.
|
| |
|
| 4. |
Remove the tip. Wait a moment for the solder
to solidify before soldering the opposite corner.

continuous flow solder tip to create
a convex bead of molten solder.

| 5.
|
Apply solder to the continuous flow solder tip
to create a convex bead of molten solder on
the tip. (See Figure 2).
|
|
Figure 3: Slowly move the tip over the
row of leads to form proper solder
fillets at each joint.
|
| 6.
|
Position the solder tip so that the solder bead
contacts the vertical portion of the J leads.
Slowly move the tip over the row of leads to
form proper solder fillets at each joint. (See
Figure 3).

Repeat steps 5 and 6 for the remaining
sides. |
