LGA - own design - how to

[justanothername]

Hello Everybody.
There is a special circuit in the company where I work we think about making a LGA package for it.
This is nothing ordinary that you can google, so I'm asking you:
* How can I prototype the LGA where do I order pcbs that small?
* Who does the potting the top or does anyone know a company that is specialised in producing a potted LGA package as prototyping service?
* Are there any design guides out there?
Thanks a lot!
M.

I think i remember exploring this avenue before. Are you talking micro SIP and MCM? If you are planning on using wafers and wire bonding then it may be worth giving quik-pak a call.

At first, I plan to use regular SMT-components on a PCB, maybe with a shielding. Like those modems (ublox). This is pretty much straight forward.
Later, I want at least to have the components potted and sealed, like a typical SIP design. Maybe use dies instead of components for further miniaturisation. I have a bonding machine at hand for prototyping, we bought it for another project and used it maybe for 100 bonds, so I may be able to prototype a lot in-house.

I would contact this company, they are not far away from you and offered me TOP service over the years: http://www.somacis.com/
