Gold circuit lines on ceramic MCM modules are cut to disable/enable certain parts of the device.

High-frequency devices often have capacitors that are trimmed to finely tune the device to a certain frequency. In this example, a gold capacitor on a ceramic substrate was trimmed using green wavelength energy.

Flex circuits are commonly found in disk drives, keyboard, microprocessors used in lap top computers and printers. In the following example, Kapton was removed from a portion of a flex circuit for failure analysis(left figure). UV(355 B") energy was used to remove the polyimide covering the copper circuit. With the copper circuit exporsed, green laser energy wan used to make the cut(right figure)
