Slant DSSD is chucked here

Edge of slant DSSD will sit on here.Þ The edge doesn’t move after the rotation.Þ Precise alignment of slant DSSD can be done in the horizontal plane on the assembly-benchÞ This jig can be applied for not only L6 but also L4,L5 ladder assembly.

With the same way,we can applied for the backward DSSDmuch more easier(since w/o gonio rotation)

Booting Lab for the assembly in IPMU.

• Automatic wire bonding machine(REBO-7S, Ultrasonic engneering Co., Ltd. ) will be delivered.

• Wire bond pull tester(Dage4000+)• Clean room(4×8m2) in class 1000.• 3D vision measuring machine which can cover

L6(Mitsutoyo, QV Apex 606, 600×650×250mm).• Glue dispenser• Some rigid tables and microscopes…• Mechanical and electorical QA system.

Summary• Somehow method to assemble forward(slant) part

become much more concrete method.- Forward and backward part (DSSDs w/ hybrid board) will

be assembled and glued on the ribs at first.- The after, straight(Origami) part will be glued on the ribs.- The jigs can be used for the other layer assembly.- The design of jigs will be finish soon.• Lab for ladder assembly in IPMU- Most of the quipment will be delivered in end of March.

61

Plan

• L6 assembly-bench and rib-jig will be delivered by end of March. The other jigs will be delivered in April.

• The other equipment for full ladder assembly also will be delivered by end of March.

• Mockup production can be started soon after delivering of jigs since no wire-bonding.

• Some tuning and training is needed before the first ladder assembly for L6. The most concern is wire bonding(optimizing bonding parameters, automating, bonding QA…).
