ABSTRACT:
An electronic cartridge that may include a cover which is attached to a thermal element. A substrate may be located between the thermal element and the cover. The cartridge may include a first pin which extends from the thermal element through a datum hole of the substrate. The cartridge may also have a second pin which extends from the thermal element through a first float hole of the substrate. The first float hole may have a major diameter and a minor diameter. The major diameter of the first float hole may be larger than the diameter of the second pin so that the second pin can move relative to the substrate. The first float hole allows movement of the second pin when there is a differential thermal expansion between the thermal element and the substrate.
