From measurement made by Stephane Bouvier :

Measurement of componants (independantly)

componants of ladder            =  585 g

all kapton buses (from wafers to connexion board)  =  40.18 g

Glue (estimation 1g  per point)  = 64*1 = 64 g (rough estimation)

grand total = 689.18 g

Measurement of a fully equipped ladder = 662,1 g

Details

Ladder :

•  Comparison of the weight of the differents parts constituing a ladder :

in GEANT, the sum of the weight of volumes describing a ladder is 605 g

In REAL life, the sum of a ladder, including all components, is 662 g (see details above)

The weight of the SSD in GEANT does not take into account screws, glue, air hoses and cables.

So the difference may be higher than 60 g.

The details are here (see page 2)

• SFSW volume :

1. the ALICE128 chip (12 ; 0,000034 kg)
2. the cylindrical part of the module pin (1 ; 0,000026 kg)
3. the base cylindrical part of the module pin (4 ; 0,000017 kg)
4. the flexible hybrid(2 ; 0,000193 kg)
5. the side part of the stiffener (4 ; 0,000066 kg)
6. the main part of the stiffener (2 ; 0,001294 kg)
7. the active silicon wafer (1 ; 0,002041)
