PAN1321-SPP ENW89811J4CF Assembly Guidelines 8.4 Assembly 8.4.1 Component Placement In order to assure a high yield, good placement on the PCB is necessary. As a rule of thumb the tolerable misplacement is 150 µm. This means that the PAN1321 module can be assembled with a variety of placement systems. It is recommended to use a vision system capable of package pad recognition and alignment that evaluates the pad locations on the package (in contrast to outline centring). This eliminates the pad to package edge tolerance. The recommendation is to pick and place the module with a nozzle in the centre of the shield. The nozzle diameter shall not be bigger than 4 mm. 8.4.2 Pin Mark 1.00 mm Pin 1 (A1) is marked on bottom footprint and on the top of the shield on the module according to Figure 9. Diameter of pin 1 mark on the shield is 0.15 mm.
