I am designing a small single-sided board and would like to use a surface mounted AVR controller, but I have run up against a small problem:
To date, I have only used DIP parts and I don't have any way of programming surface mount parts out of circuit.
I have come up with some potential solutions, but they are not appealing at all.
1. Lay out an ISP connector on the board, then saw off the connector after the chip is programmed. This would compromise the layout, which is a problem because there is RF circuitry right next to the controller, and
2. Solder very tiny wires from an off-board ISP connector to the chip. Not a much better solution given that I might have to use a TQFP package (and my hands aren't as steady as they were when I was 20).
So...why don't I just buy a programming adapter? Because I am very tight and if I did want to spend the money, there doesn't seem to be a place to get one here in upcountry Thailand,
I know there are some pretty experienced and creative people on this forum, so I thought it worth posting here to see if anybody here had any good ideas.
Thank you in advance for considering my problem.
