Surface mount programming?

[dhouston]

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

You'll never have any answer in the schematic area.. as it's the place to post working example... euh.. in theory so far.

Looking at your schematic... there's no resistor and diode on the MCLR/VPP line. compare your schematic with Sayzer's one o rthis one on the Melabs website...

[Tobias]

Reading the support page on the ICSP the diode and resistor are only for the protection of other components.

"If 13V on the MCLR pin might put at risk other components on your board, use a diode in series with the RESET pullup to keep the 13V off of the Vdd line."
