The industry trend is to reduce part count, and the PCB is snapped into the internal under cuts on increase ease of assembly. Both of these concerns the baseplate (Figure 1) causing the cantilever beams drive the need for snap tit designs into every new to deflect outward. Then the baseplate subassembly product.
