Hi all
I want to suggest that the next rev of UNO will come with a zip socket instead of the regular socket for the
main micro controller .
Thanks

I think you mean "ZIF"  (Zero Insertion Force) socket.

Whatever
zip or zif

I think it would be impractical, as ZIF sockets can be kinda bulky and the controller itself is not commonly replaced on a daily basis. A variant might be a good idea, but having it on the flagship board would add unnecessary bulk and require large spacers for shields, which would probably affect more users than the use of a regular socket.
The Arduino board is not really intended as a bulk programming target, anyway. You can easily throw together one on perfboard, however, or even set it up on breadboard and skip socketing alltogether.

Probably a "better" addition would be a micro SD on the back side. This is very practical for logging etc. It does not need to be populated by default, but it costs close to nothing and brings tons of memory.

My idea is to enable a limited number of production version of the project done on UNO
on another oem board without using a programmer .

Thanks

Have you looked at a ZIF socket?
All the ones I've seen are too tall to be able to use a shield if
it were used on an arduino board.

For about $3 you can get a USBASP ISP programmer and program any chip in place without a bootloader.

And anybody that needs to burn multiple chips can build up a rig to do this.
You could use your existing arduino or any ISP programmer
then solder a zif on a board like this:

or easily make your own board to hold the socket. There really isn't anything to it.

You could also buy shield kit like this and use your Arduino or an ISP programmer:

Here is my method. Soldered the ZIF socket pins to a dip header and soldered that into a small standalone 328p based board, which included a 16Mhz resonator and ICP pins. That's a USBtiny programmer below the 'target' board.

ooooo, Now that thats a good idea!
I've had looked at using a ZIF on a few of my boards but the pins on a ZIF are to wide
for the holes on some boards.

Many thanks to all !

Yes, that is exactly what I found also, hense the Rube Goldberg method, but it works. Soldering The ZIF pins to the DIP header was a little tricky as one really needs to have a chip installed into the ZIF and the lever closed so all the ZIF pins are near vertical, before soldering to the header pins.
