I have about 30 PCBs that I populated with SMD components using the "Skillet reflow method". I have a pogo pin jig to connect an AVRISPMK2 to this board. Some boards I can program just fine using winavr on vista ( this PC also has studio 4 and 6 installed ), but the majorty of boards I am trying to program fail with the following output below.

I have tried 2 different programmers and some boards that I am able to program once, I cannot return to and reprogram with reliability.

Any thoughts would be appreciated.

I would guess that your soldering is not 100%.

Or your pogo-pins are not the full ticket.

Or some components have got too hot in the frying process.

Thanks David,

I was thinking the same things.

I rang out the µC pin to ISP connector successfully on several of the failed boards.

The jig I made is a bit daft. I guess I should try to make a better one.

I unsoldered my attiny85 from one failed board and replaced it with a new hand soldered µC and the problem persisted.

I am leaning towards the pogo pin jig at this point.

Nothing to do with AS6 it seems, moving to the AVR forum.

Although the jig could be the problem, it could also be ANYWHERE else in the circuit.

A bad power supply will cause it to fail.

Using and external crystal? A poor connection to the crystal or its caps, and their connections to ground will cause it to fail.

A poor connection to a by-pass cap can give erratic or complete failure.

The list goes on and on.

The fact that several of the PCBs work is a good thing, as it tells you that that design, and layout, and software CAN work, if the assembly, and programming connector(s), work.

If you have a bunch of failures you could certainly try re-soldering one by hand, or re-reflowing it, and seeing if it then works properly.
