Abstract
A laser cut technology, suitable in fine pitch substrate, is disclosed in the present invention. The laser cut technology comprises the following steps. First, a metal layer is coated on the part that is being cut on a substrate. Then, one end of the metal layer is connected to a meter. The metal layer is cut to the width and pitch by a laser, and at least a trace will then be obtained on the metal layer, wherein one end of the trace is connected to the meter. Finally, measure the impedance of the trace and see if it meets the requirement.
