> G'day Edwin,
> I guess the easiest way to explain it is that you want to check the
> continuity of solder joints. Take for example a component with 10
> Pins,
> Pins (1,2) (3,4) (5,6) (7,8) (9,10) are electrically connected
> internal
> to the daisy chain component. When you lay the Board out Pads (2,3)
> (4,5) (6,7) (8,9) are connected. The component pins are now daisy
> chained. When you send it through your process you can check the
> integrity of your solder joints by simply metering between pins 1 and
> 10
> which will result in either a short circuit or open circuit. Open
> circuit look at your process, Short circuit you could be on a winner.
