3.4 Adhering the grid
3.4.1 Precautions
•
Before assembling the grid unit, make sure that the work bench is flat and clean.
•
The grid must be handled very carefully since it is not structurally strong. No guarantees are
made for its ability to withstand the mechanical damage which might be sustained if the grid
assembly is dropped, for instance, while the product is being used, stored or transported.
•
If the grid thickness is 3.5 mm to 3.7 mm (including the thickness of the adhesive tape), the
grid spacers do not need to be used.
3.4.2 Flow of grid adhesion steps
1) Adhere the double-sided tapes to the grid.
2) Adhere the grid spacers to the grid.
3) Adhere the double-sided tapes to the grid spacers.
4) Place the grid sticking tool on the grid frame.
5) Adhere the grid to the grid frame.
6) Remove the grid sticking tool from the grid frame.
7) Apply pressure to the adhered grid, place the grid weight tool on the grid, and leave
standing for 20 minutes.
8) Adhere the accompanying grid labels.
3.4.3 Grid adhesion procedure
1) Wipe both sides of the grid spacers (short and long) with ethanol to remove any oil or
grease.
2) Peel off the backing paper on the double-sided tape which has been adhered to the grid.
If the grid does not have the double-sided tape, attach the double-sided tape (Sumitomo
3M Y-4930) to the grid after wiping the surface where the double-sided tape is attached
to with ethanol to remove any oil or grease.
3) Align the grid sticking tool with the short side of the grid, and place it in position.
Check that there is no gap between the grid and tool.
