1. A method of assembling a multilayer panel for use in a heat exchanger, the method comprising:
positioning a frame on a work platform, the frame having two header sections and a middle section, the middle section defining a heat transfer fluid area and each header section defining a frame alignment feature;
positioning a heat exchange sheet on the frame across the middle section and each header section, the heat exchange sheet having two sheet alignment features each corresponding to one of the frame alignment features, wherein at least one of the two sheet alignment features includes a flexure formed within the heat exchange sheet, the flexure defining a flexible region on the heat exchange sheet;
inserting an alignment pin of the work platform into each of the corresponding frame and sheet alignment features; and
welding the heat exchange sheet to the frame.
