My AVR-ISP lite programmer finally came in the mail today (only 3+ weeks). And now I can begin some other projects that I have been waiting to do. With that in mind I now need to solder on my Atmel Atmega48 chips onto a breakout board.
Once that was done, I took solder braid and sucked up all the excess solder to reveal nice soldered connections. Can not even till that they were done by a simple soldering iron.
My starting point: the board by itself.
The first thing to do is line up the ic chip perfectly on the board. I really want to emphasize the perfectly part because smd solder does not allow for many mistakes or much tolerance.
Once the chip is lined up, you need to hold it in place to be solder. I use electrical tape to keep it in place temporarly. After that, you can finally solder the first pin down. I typically solder another pin down to hold the chip in place.
Once the chip is held in place, I solder a line across all four sides of the chip covering all the pins. At this point its fine to have sloppy solder down.
Once that was done, I took solder braid and sucked up all the excess solder to reveal nice soldered connections. Can not even till that they were done by a simple soldering iron.
Now my chip is ready to use. Hopefully the ISP programmer works.
