Daisy chain mechanical data

The daisy chain sample features two-by-two pin connections. The schematics in Figure 68

illustrate the way pins connect to each other. This sample is used to test continuity on your

board. Your PCB needs to be designed the opposite way, so that pins that are unconnected

in the daisy chain sample, are connected on your PCB. If you do this, by simply connecting

an Ohmmeter between pin A1 and pin A3, the soldering process continuity can be tested.
