I figured I tore down one of the Wilocity WiGig antennas, may as well tear down one of the Intel ones.

So this antenna is a 2x10 array, its not on a ceramic board, but instead seems to be some form of fiberglass,  It also has soldermask and silkscreen.

I had some difficulty getting the shield off and some components got bumped/toasted.  They used some underfil on the main RF IC.  This made it very hard to remove.  The solder mask also makes it impossible to see the track from the X.fl connector.  I suspect the interface is similar to the Wilocity Antenna.  There are 2 baluns next to the chip, wonder if it takes in a differential signal from coax?

You can see some of the underfill was left behind.  It also looks like the underfill pulled up the soldermask where it came up with the chip.  I cant discern any kind of pattern on this chip that would indicate which balls the RF comes from.

The bottom of the chip is covered in the underfill so we can see any of the pretty silicon.  If anyone has any advice on how to remove this stuff without hurting the silicon below let me know.

A bit chipped off the side and you can see the silicon underneath.
