Looking for proto QFN board
« on: March 14, 2013, 01:38:26 pm »
I am looking for prototype board for 20-QFN footprint.
Here is the chip: Si4712/13-B30

The footprint does not look quite regular QFN package since there is some pad at each corner.
I have look at sparkfun digikey and farnell but did not found the appropriate proto-board.

Thanks for the help

unfortunately, the link you posted does not work for me, so I can't see the actual chip.
Have you tried to find some from vendors like Abra, they sell schmart boards, or perhaps on Ebay?  other ????

Thanks both for you answer. I have also update the link in the post so you may now be able to look at it.

I can't really help, but here's the datasheet if anybody wants to take a look at this.

Make your own proto-board..... built into your first prototype!  The recommended land pattern is on page 37 and the sample application circuit from the data sheet looks pretty simple.  Breadboards are so 20th century :)
