1) CS Test (3/6)

CS Test Decision Criteria 1 : Leave the subject untouched

• Fail if a touch (Ghost Touch) is detected at a certain frequency

CS Test Decision Criteria 2 : When touching the subject

• Generally done with a 10 phi touch probe

• Fail if a touch is not detected (Insensitivity) at a certain frequency after actual touch

• Thus, pass only if touch is detected every time A DIFF value less than THD from measurement is considered an Insensitivity, and evaluated as fail.

• New set with ABOV device has no Ghost Touch (Pass)

Water Tolerance Test 2 : “Pour and wipe water” on the front panel

• Previous set with ATMEL device resulted in an Insensitivity (Fail)

• New set with ABOV device has touch key operating normally (Pass)

Ghost Touch prevented throughwater tolerance algorithm

H/W Design Guide for ABOV Touch Solutions


ㅏ

1) Pattern, Gap between GND, Via

Touch Key Pattern

Horizontal isolation betweenpattern and GND1.0mm recommended (Min. 0.8mm ~ Max. 2.0mm)

GND Pattern

Via HoleVia Hole located wherethe channel routing distanceis the shortest

Channel Routing

■ When there is GND pattern around Touch Key pattern

Horizontal / Vertical isolation between patterns: Min. 0.8mm, 1.0mm recommended, Max.2.0mm

■ Locate Via Hole at the corner of the Touch Key pattern to minimize channel routing distance


2) Channel Routing (Trace)

■ This slide is a basic design guide to touch channel routing(Trace)

■ Trace Width should be designed at a width as small as possible by the board manufacturing process

For example, it is 80um for FPCB (Flexible Printed Circuit Board).

It is 150um (0.15mm) ~ 200um (0.2mm) for normal PCB (Rigid PCB).

■ Minimum for Trace Gap between Routings is same for above process.

For example, it is 80um for FPCB, and 150um(0.15mm) ~ 200um(0.2mm) for normal PCB.

Maximum gap is 200um for FPCB, 300um(0.3mm) for normal PCB.

■ Minimum is the Same for Trace Gap between Routings and GND

Minimum is 80um for FPCB, and 150um(0.15mm) ~ 200um(0.2mm) for normal PCB.

Maximum gap is 200um for FPCB, 1mm for normal PCB.

■ Channel Routing should be as short as possible (maximum within 150mm),and must ensure the entire routing structure is not in a rotating form (curl or U-shaped).


3) Channel Routing and Via

2) When IC and pattern is on a different side or layer, using Via 1 hole recommended

3) In case of 2), maximum 3 Via holes can be used

Solid Line : FrontDotted Line : Bottom or other layer

Touch Panel (Front)

■ When sensor IC and touch pattern is on a different side or layer, it is recommended to use Via 1 hole. Please refer to 2) below.

■ If needed, maximum 3 holes can be used but it is not recommended to use any more than that.


4) Board Design (Top)

Gap typ. 1mm

■ Top Side

Minimize exposed routing on the front side as possible

Pattern size 10mm X 10mm, gap between pattern & GND 1mm (Max. 2mm)


5) Board Design (Bottom)

Touch Sensor IC

Place Touch Key channel DC resistors

■ Bottom Side

Place channel DC resistors near Touch Sensor IC as possible.

Channel routing should be as short as possible and simple in form.

(U-shape or rotating form should be avoided)

Glossary

Digital Filter Solution : 1) Glossary

▶ The raw data is primary data collected from the touch IP.

Raw Data

▶ The baseline is the reference line for raw data during untouched status.

Baseline

▶ The baseline tracking is the process of updating the base for raw data during untouched status.

▶ If the sensor is touched, the baseline tracking is put on hold.

Baseline Tracking

▶ The difference data is the difference between raw data and baseline.

▶ The touch detection depends on the threshold and difference data.

▶ If the diff. data exceeds the threshold, the touch result is ‘detected.’
