Surface mount programming?

[kevj]

I have one of the USB programmers with the ZIF socket for DIP packages, but my design is about to got production with the SOIC version of my pic - how do I program this thing for final prototyping? Do they make another programmer or can I just add a terminal to my Pcb?only a couple pins are actually used for programming right?

mel makes adapters with ZIF sockets for SOIC.

Or, as you surmised you can do it after the chip is mounted if you provide ways to make the connections. The PIC datasheets have a section on ICSP showing which pins are used. You may need ways to isolate the circuitry depending on how your design uses the programming pins. Start with the datasheet.

Kevj,

As dhouston mentioned, you should design your circuit compatible with ICSP connector.

Attached is an example for on-board programming operation.

You can easily get the idea how it works.

Only thing to pay attention for is to isolate programming pins from the rest of the circuit.

I suggest fitting the ICSP connector to all new designs. There will always be a need to move the goalposts when in production, and you can reprogram units at any time.

ICSP header are nice indeed, you could still build a cheap SMD adapter using a IC Clip, so you don't waste any PCB space.

Look at the following

I posted a similar question in the schematics area. Attached is a PDF, I can't get my ICSP to work correctly. I get a message that the PIC doesn't match the selected. Please suggest some points to check based on attached PDF.
Thanks
