Flexible cable, flexible cable mount method, semiconductor device with flexible cable, led array head with flexible cable, image forming apparatus with such led array head
Distortion of an LED array head is eliminated by correcting an electrode pitch misalignment between an LED array substrate and a driver substrate to be caused by thermal expansion or contraction during thermal pressure bonding of a flexible cable. A tear preventing hole is formed in each area between adjacent four-divided areas of the flexible cable. When positions of the flexible cable and driver substrate are to be aligned, a pitch shift adjusting slit line is cut in order to correct the position misalignment to be caused by thermal expansion or contraction generated when the flexible cable is thermal-pressure bonded to the LED substrate. The pitch shift adjusting slit line is formed in the connection area between adjacent four-divided areas.
