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