UProblem

Large amount of warranty cost is spent in the form of replacement of PCB’s and
freight charges by Motorola and Carriers. This is due to the fact that up to 10%
Phones returned to service shops are identified as liquid damaged. There is no
mechanism of a quick on the spot diagnosis method to detect the liquid damage.

USolution

Following extensive testing and reviews it has been established that our products
need a mechanism in the form of a “Water Detect Label” to detect the liquid
damage early in the service cycle. When the Water Detection Labels get wet,
they change color from white to red permanently.

Two labels per phone will be placed.

• One (external) placed near the bar code label to be visible along
with the bar code label.

• The second label (Internal) will be placed on the transceiver (PCB)

The Second label (internal) is a back-up / second identifier placed near the I/O
connector (Accessory or External connector) on top of a Can/Shield or on the
PCB on either side.

The exact location of the label will be determined by mechanical design team
based upon the Z-axis stack-up. Ideal location includes primary water ingress
locations. The external label will be used at the point of return to check if the
phone was subject to liquid damage and dealt with accordingly. The internal label
will be used to verify/confirm the liquid damage if the need arises.

Efforts are already underway to have water detect labels placed on all Motorola
phones.
