Abstract
Methods and devices for testing flex cable shielding of a consumer electronic device are provided. In one example, a method may include applying a signal across a first portion of the flex cable shielding and a second portion of the flex cable shielding. The method may also include detecting a parameter associated with the signal. The method may include determining a health of the flex cable shielding based at least partially on the detected parameter.
Claims24
A method performed by test circuitry for testing flex cable shielding of a consumer electronic device comprising:
- applying a signal across a first portion of the flex cable shielding and a second portion of the flex cable shielding, the first and second portions of the flex cable shielding on opposite sides of a flex cable;
- detecting a parameter associated with the signal;
- and
- determining whether a break exists in the flex cable shielding based at least partially on the detected parameter.
A consumer electronic device comprising:
- a first component;
- a second component;
- a flex cable having a first end coupled to the first component and a second end coupled to the second component;
- and
- a processing device coupled to the flex cable and capable of applying a signal across a first portion of a flex cable shielding and a second portion of the flex cable shielding wherein the first and second portions of the flex cable shielding are located on opposite sides of a flex cable, detecting a parameter associated with the signal, and determining a health of the flex cable shielding based at least partially on the detected parameter, wherein determining the health of the flex cable shielding includes determining whether a break exists in the flex cable shielding.
A method of manufacturing a consumer electronic device comprising:
- providing a touch panel configured to use a flex cable;
- testing a flex cable shielding by performing the following:
- applying a signal across a first portion of the flex cable shielding and a second portion of the flex cable shielding, the first and second portions of the flex cable shielding on opposite sides of a flex cable;
- detecting a parameter associated with the signal;
- and
- determining a health of the flex cable shielding based at least partially on the detected parameter, wherein determining the health of the flex cable shielding includes determining whether a break exists in the flex cable shielding;
- coupling the flex cable to the touch panel based at least partially on the determined health of the flex cable shielding;
- and
- coupling a processing device to the touch panel.
