Soldering a small 20-Lead TSSOP IC might seem a difficult task, but by applying some very simple techniques, even the not so skillful amateur can have success.
The photo, taken using a small USB webcam in macro mode, shows a manually soldered AD9834 TSSOP SMD chip. This was achieved using the following procedure:
1. apply water based flux to the board
2. apply some solder to the tracks
3. remove excess solder with solder wick
4. align the IC
5. add some more flux
5. gentle touch each lead to re-flow the solder
PCB was done using the toner transfer method.
