As per P2 evaluation Design Idea -5 layout condition we had calculated the cost in Nitto Tape & presented to HAC-ID Management and in worst case if Nitto tape get failed HAC-ID will go with 3M tape ( Thickness-1.2 mm & Width-6.0 mm) moreover at that time HAC-AO judged the layout condition OK .
Now lateron HAC-AO cross varified the design layout as oer Idea-5 from HAC-T & confirmed that Protctection function is less than 60% so HAC-T proposed to change the design layout and later on same was reflected in the C1 drawing , morover no information was circulated to HAC-ID
When HAC-ID received the C1 drawing we expected that Idea-5 is considered but HAC-AO changed the Drawing condition from P2 condition , HAC-ID did the design feasibility from supplier as per C1 drawing and in 3D data supplier has no major design concern.we will share you the complete design feasibility report by 13-May'15
From Drawing direction point of view its HAC-AO call which design to be reflected at Tool go timing from the view point of protection( Please discuss with Goto San & Yoshida San)
From HAC-ID point of view both IDEA-5 & C1 drawing is possible to manufacturer
Please take final opinion from Yoshida San & Goto San before issuing final design & drawing direction
Note: Cost information I have already shared to you.
Dear Yoshida San/Goto San,
Please give me your final direction over this matter
