Learn how to solder surface mount components onto a circuit board from expert Jeff Koskulics in this Howcast video.
Now, surface non-components are a little bit different from through-hole devices, in that they don’t have wire leaves that pass through the board. So it’s a little bit more of a challenge to solder them to a circuit board. We have to insure that they are held in place in position of the board mechanically, before we let the solder solidify.
So what we’re going to do is use a trick, where we solder one of the terminals of the device first and remove the soldering iron, allow it to solidify before we let go with the tweezers that we’re going to use to hold it.
So we’re going to solder this service mount capacitor to this terminal here. So we begin by applying solder to one of the terminals to create a little pool of solder which will hold our device in place.
Next, we position the device on the board, holding with the tweezers. Once it’s in position we’ll melt the solder. The solder then will flow around the device. We’ll remove the tip, wait for the solder to solidify, and remove the tweezers. Now our device is firmly held in place. And we can finish by soldering the other terminal.
And that’s how to solder a service mount device by hand.
