A review of SMT stencils from BEST, Inc. 10% off coupon: 'Curious'
Here's a quick video of drag soldering--a technique that enables you to quickly solder entire sides of ICs by simply dragging the iron across all the pins. The key is starting with the right amount of solder, and adding generous flux. The results are often better and more uniform than individual pin soldering.
When soldering a lot of surface mount chips, or when you don't have a clamp handy, sometimes the best solution is just a piece or two of double-sided tape between the board and desk. "De-stick" the tape a little by touching it with your fingers to avoid permanent additions to your desk and to make it easier to rotate the board when needed. Only a small amount of tape is needed.
