1. Replace the touch key sensor PWB in a clean room.

Be sure to remove the dust from the unit before carrying it into the clean room.

2. Remove the touch key sensor PWB from the front glass.

3. Clean the bonding surface with alcohol.

Depending on the dirt, water solution of 80%vol can be effective.

4. Adhere a spacer before bonding the touch unit.

* When peeling the ITO section, check that there is no glue

residue on the front glass.
If glue residue, dirt, fingerprints, etc. are found, wipe them
off with anhydrous alcohol.
Do not apply anhydrous alcohol to the double-sided tape
on the metal part attaching to the glass.

ii-1. Peel the release paper of the double-sided

tape on the FPCB section.

ii-2. Adhere the spacer to the FPCB section.

(Use the right and upper sides of the FPCB
section as a reference.)

* Check that the spacer does not contact with

the ITO section.

* Be careful not to apply stress to the joint of FPCB and ITO.

ζ-3. Peel the tape fixing the FPCB and ITO sections.

ζ-4. Peel the protective sheet of the ITO section.
ζ-5. Adhere the light shielding sheet.

(Use the lower side of the FPCB section and the notch
on the ITO section as a reference.)

* Be careful not to get the ITO section dirty with

fingerprints, etc.

* Be careful no tot leave space between the light

shielding sheet and the FPCB section.

ζ-6. Peel the protective sheet.

5. Attach the touch unit bonding procedure.

It includes peeling of the protective sheet.

How to mount the touch sensor

i)

Adhere the FPCB to the glass. (Do not warp the FPCB if possible.)

ii) Peel the protective sheet by means of the pull tap for peeling the protective sheet.

iii) Adhere after positioned using the positioning jig.

iv) Peel the protective sheet of the OCA.

Lift the ITO section, then peel the protective sheet by about half by means of the pull tap.

v) Contact the FPCB and joint end of the transparent electrode film with the glass.

* Grasp the opposite end. Note that the ITO is positioned by adhering.

Pull tap for peeling the protective sheet of the double-sided tape in the FPCB section.

* Peeling it completely reduces workability.

Check the order due to workability.

Adhere first.

*Note: Do not bend the PWB (FPCB section)

and sheet (ITO section).
