Overview Nothing is as fast and fun as prototyping on a breadboard, but at some point you will find that the chips you want to work with are only available in non-breadboard-friendly SMT/SMD (Surface Mount Technology/Surface Mount Device). Unlike most DIP chips and resistors, SMT parts do not have the leads going through holes in the PCB. Instead, they 'float' on top, with oftenrectangular solder pads.
Required Tools With ALL SMT work, having the right tools is essential! You will need tweezers. Either straighttip style (available here) (http://adafru.it/421) Or curved (available here) (http://adafru.it/422) You'll also need a soldering iron with a fine tip. Although a good iron is a little expensive, its the most important tool and we suggest investing in a good one. Our favorite is the Hakko FX888D (http://adafru.it/1204) with the fine SMT tip (http://adafru.

Soldering an SOIC We'll start by showing how to solder an SOIC component. Although we have many different 'package' versions available (such as SOIC/TSSOP/QFP/QFN) SOIC is the easiest to start with and its the chip I needed to work with today so that's what we're going to do :) Begin by placing the breakout adapter into your vise/third hand to keep it steady. We'll start by melting a little solder on one corner pad. I like going with the top right corner.
Once you've identified which is pin 1, hold the chip with the tweezers over the pads and then re-heat the corner pad you soldered onto a few steps ago. Now you can 'fix' the chip in place by soldering in the opposite corner. The one pin you soldered will keep the chip in place mostly, so you just have to solder the other pin a little to make the setup secure Go ahead and solder the remaining pins now © Adafruit Industries http://learn.adafruit.
The hard part's done! Now we can solder on regular 0.1" spaced male header. We like the break-away kind so its easy to get just the right amount. (You can get some at the adafruit shop if you don't have any!) (http://adafru.it/392) Break two pieces the same length as the pads on either side of the PCB and place them into a breadboard, long pins down.

Page 2 of 3 DESCRIPTION - Beguiled by a fancy new chip that is only available in a QFP or QFN pinout? This breakout PCB set will make your life much much easier and get you prototyping faster than ever. One side has a 32-QFP pin out with traces going to two rows of 0.1" spaced holes, the other has 32-QFN. Solder your chip to either side and you're ready to rock on any solderless breadboard.
