Perfect solder joint, step 1 of 4

•Hold the iron touching one of the pads for a count of one•Make sure to touch the side of the iron tip to the pad, not the actual tip of the iron

Perfect solder joint, step 2 of 4

•Feed a tiny bit of solder onto the pad while continuing to hold the iron to the pad•Feed enough solder onto the pad to cover the pad, but no more

Perfect solder joint, step 3 of 4

•Continue to hold the soldering iron on the pad and pick up your component using the tweezers with your other hand•Make sure the tweezers are making contact only with the sides of the component that do not have leads, otherwise you may get your tweezers in the solder

Perfect solder joint, step 3 of 4

•Continue to hold the soldering iron on the pad so the solder stays liquid•Slide the component into the solder from the side while keeping the bottom of the component flat on the PCB•Make sure you slide the component far enough into the pad so that the pad on the other side of the component is at least half exposed

Perfect solder joint, step 4 of 4

•Continue to hold the component on the pad with your tweezers and remove the soldering iron, wait for the solder to solidify and then remove your tweezers

Oops.

•If you don’t slide the component in from the side you may wind up with a component that does not touch pads on both sides•If this happens just reflow the solder on the first join and replace the component

Here’s How to Use Solder Wick

•Apply flux to the solder you want to remove•Place the solder wick on top of the solder you want to remove•Sandwich the solder wick between the solder and your iron until the heat sucks the solder into the wick
