Disclosed are methods and apparatuses for overcoming known plating deficiencies in evaporator assemblies in ice making machine. One embodiment joins the vertical and horizontal partitions together at their intersections so that all surfaces are susceptible for increased soldering/brazing by eliminating the “voids” by changing the location and design of the “weep holes” in the vertical and/or horizontal partitions.
