General MIPI SMIA specs:

cal_Specification_1.0.pdf


Hard to find anywhere

Somebody should try to contact 
http://originalspareparts.com.ua/parts/5400385/socket_smia95_through_
board_r21/

Today I sent an inquiry to the mail addr in 
http://launch3telecom.com/pdf/nokia/smia95.pdf



Alternative: think about using the ONboard type (

973a1/$FILE/SMIA95.pdf ), which seems a tiny bit easier to source. 
Might be feasible when placing the socket on upper-board

N97 cam module seems a working alternative of identical component in 
a different package (flex with B2B connector)
Height of N97 cam module incl steel shielding/fixture: ~8.5mm. 
Distance from felt ring in case till upper rim aka kbd frame outer 
surface (roundabout where we see lower side of UPPER): 10.8mm. So we 
have a ~2.5mm for a patch of ds-sticky PU foam (after compression) 
to mount the N97 cam to UPPER.
Usung this approach we don't need SMIA95 but have to find a 
mat(ch)ing female connector for the hirose B2B on cam module's flex

The Panasonic AXE720127A looks as if it may be compatible with the 
connector on the FPC:
http://pewa.panasonic.com/assets/pcsd/catalog/a35s-catalog.pdf

Digi-Key: USD 1.41, no stock, MOQ 500, 2 months lead time.
Mouser: USD 1.41, no stock, MOQ 320, 8 weeks factory lead time.
Arrow: USD 1.70, no stock, MOQ 500.
Avnet: not in catalog.
Farnell: not in catalog.

Seems that we may have to ask Panasonic for samples.

Correction: AXE720127A can't be the the right part. We verified the 
connector geometry again and found out that the pich isn't 0.35 mm 
but the much more common 0.40 mm. We're still searching for 
something that really fits.

Characteristics of the connector on the FPC: 0.4 mm pitch, 20 pins, 
metal fittings on the short (!) sides, total length of plastic about 
5.1 mm, width of plastic/contacts about 1.5 mm, height of connector 
(without mating part), about 0.6-0.7 mm.

Especially the fittings on the side seem to be quite unique.

Comment 6 by Werner Almesberger, Jul 14, 2014

Good news: I think I found it. The critter on the FPC seems to be a 
Hirose DF37B-20DP-0.4V(53). Digi-Key don't have the correct picture 
of it, that's why I missed it before.

http://www.hirose.co.jp/cataloge_hp/ed_DF37_20140305.pdf

We'll probably want the DF37NB-20DS-0.4V(51), though the 
DF37NC-20DS-0.4V(51) (no fittings) should also work.

Digi-Key: USD 0.44 @ 1000, 8076 in stock.

(51)/H11849CT-ND/2230649

Also available at Mouser (same price, 4500 stock) and listed but 
non-stock at Avnet. Farnell has the series but not this part. Arrow 
knows nothing of it.

Preliminary additional info:
length of flex cable from module boddy til end: ~ 16.2m
connector start (side closer to module): ~5.5mm from flex end
connector end: ~1.5mm from flex end

looking at back of cam and onto the B2B-conn, cam left conn right, 
using a countinc scheme of
10 11
09 12
08 13
07 14
06 15
05 16
04 17
03 18
02 19
01 20

it seems that pin 11, 14, 17 are connected to the shielding 
"backside" huge "trace" of the FPC, which 
suggests they are on GND and above numbering scheme in line with 
schematics of #3 
http://projects.goldelico.com/p/neo900/issues/515/#ic1908.

Checked by visual inspection with light-thru and top-light

Comment 9 by Joerg Reisenweber, Sep 22, 2014

pin 2 and pin 5 and pin 8 as well, so yes, this definitedly is the 
right numbering scheme
