ADVANCED INSPECTION METHOD UTILIZING SHORT PULSES LED ILLUMINATION

摘要

PURPOSE: An improved inspecting method using an LED lamp of a short pulse is provided to use a strip cable, thereby reducing distortion induced from a pulse current. CONSTITUTION: A strip cable(230) includes a form factor and a plurality of conductors. An LED group is coupled with an LED driver by the strip cable. The LED driver operates an operating signal which has short time for maintaining a high current through the strip cable to operate the LED group. The LED group generates a light pulse in response to an operating signal which has short time for maintaining a high current.
