Abstract
An LED array print head for an electrophotographic printer includes: LED array device packages each being loaded with an array of LEDs individually connected to a first major surface of the LED package by first solder joints; LED driver packages each loaded with a driver circuit connected to a first major surface of the driver package by second solder joints; and an optically transparent insulative substrate with a first major surface carrying conductive leads adapted to electrically connect the LEDs and driver circuits. The LED and driver packages are mounted on the substrate in such an orientation that the first major surfaces of the packages face the first major surface of the substrate and the first and second solder joints are connected to the conductive leads of the substrate.
