Here's a neat trick I use to solder smt parts as small as 1/10th watt resistors. Use a small strip (about 3/16 wide, 1 inch long) to pick up half of the chip. One strip of tape will solder about 20 parts before it becomes useless. I put the chip resistor on the table and lay it over half the device. Pick it up with the tape and "tape" in in place where you want it. Solder the exposed end first, then remove the tape and solder the other end. This makes for accurate placement of the device. Use only masking tape. No plastic electrical tape. Use a 20 watt soldering pencil with a needle point. Use only .015 dia low temp solder. This is the cheapest way. Once you get enough money and you do a lot of smt work, get a hot air system to solder with. No iron and nothing touches the device but the solder and the hot air. If you can find some solder "paste", a combination of minute solder nodules and flux, nothing touches the work but the heat. You might be able to obtain this paste from someonethat does a lot of smt rework.
