9.0 Assembly Guidelines
The target of this chapter is to provide guidelines for customers to successfully
introduce the eUniStone module in production. This includes general description, PCB-
design, solder printing process, assembly, soldering process, rework and inspection.
9.1 General Description of the Module
eUniStone is a Land Grid Array (LGA 6x12) module made for surface mounting. The
pad diameter is 0.6 mm and the pitch 1.2 mm.
All solder joints on the module will reflow during soldering on the mother board. All
components and shield will stay in place due to wetting force. Wave soldering is not
possible.
Surface treatment on the module pads is Nickel (5-8 µm)/Gold (0.04 - 0.10 µm).
Figure 13 shows the pad layout on the module, seen from the component side.
