These instructions will help you familiarize yourself with the initial difficulty of soldering surface mount components. By the time you have finished, you will be able to solder components with pins with .5mm spacing.
Tools and Supplies
1. x1 soldering iron (digital or analog)
2. PCB(Printed Circuit Board) with available pads
3. SMD (Surface Mount Device) component that matches the available pad
4. Solder (recommend water soluble, rosin core acceptable)
5. Desoldering braid
6. Flux w/ applicator
8. Rubbing alcohol (rosin core solder) OR
9. Water (for water soluble solder)
10. Anti-static cloth
Step 1: Preparing the PCB
2. Clean the PCB of any dust or debris.
3. Turn the soldering iron on now, and set the temperature between 600-700 degrees.
Warning: When heated to these temperatures, you will be burned if you touch the tip of the soldering iron.
Step 2: Use Tweezers to Position the Component
Step 3: Tack Down One Corner
2. By now, the soldering iron should be hot. Get a small to medium sized dot of solder on the tip.
3. Pick any corner pin on the component
4 . Touch and hold the soldering iron to the pad that will be associated with that pin.
5. If you have done this correctly, the solder should have transferred from the pad on the circuit board to the component pin, it does not matter if you have connected excess pins, this will be fixed later.
Step 4: Flux
1. This substance is messy, so be sure to use an applicator. (toothpick, brush, etc.) In this case, I have used a metal tip.
2. Get a large amount of flux on the applicator.
3. Spread the flux over the pins on the opposite side of the component that was tacked down in the previous step.
Step 5: Solder
2. Use the soldering iron to heat up the pad, not the pin on the component.
3. While the pin is hot, position the solder between the pad and the pin. The heat will melt the solder, and the flux will cause it to flow where it needs to.
4. Repeat this as many times as necessary.
Step 6: Heat Up Desoldering Wick to Fix Tack
These steps will also work for removing the component from the board.
1. Take the desoldering wick and place it over the solder you want to remove.
2. With the soldering iron, lightly press on the wick, to ensure the heat is transferred through to the solder.
Warning: Remember that heat removes solder, not pressure. Too much pressure applied could remove the pad or pin on the component, ruining the component or board.
Step 7: Solder
Step 8: Fix Any Remaining Solder Bridges
Step 9: Clean With Rubbing Alcohol
1. Take the anti-static cloth and pour a small amount of rubbing alcohol onto it.
2. Gently clean around the newly soldered component, and where any excess flux exists. This will give a more professional look.
