Mastering the Art of Soldering
4.8.1 Steps in Soldering Surface Mount Chip
1. First, you have to apply the flux to the pad or the contact point where it will be placed.
Using tweezers, place and align the chip.
Do not put the chip yet.
You may use loupe
to ensure that the pins are properly positioned on their pads. Be careful not to bend the
pins.
2. Before placing the component onto the surface, add a small amount of solder to the pad
where the component is going to be installed.
Application of solder to one pad
3. While warming the solder on that pad, use the tweezers to put the component in place. If it
is not aligned properly, you can make adjustments while the solder is still melting, or just
reheat the pad, re-align, hold still, and remove the soldering iron.

4. Before proceeding to soldering all the other pins, use a loupe to make sure the alignment
is good. Then solder all the remaining pins while continuing to check the placement of the
component.
