Connectivity Test for EES Logic Probe Project

  1. 1. Connectivity test Week 12
  2. 2. Get ready the multi-meter 1. Turn the switch to measure ohm (x10) 2. Short the two probes to test that the multi-meter is working properly 3. Check that the needle will swing towards the right
  3. 3. Chip holder – test short circuit1. One probe on pin 1 2. Another probe on copper side but at a distance 3. Confirm short circuit 4. Continue to pins 2 - 14
  4. 4. Chip holder – test open circuit 1 1. Place the two probes on adjacent tracks 2. Confirm open circuit 3. Repeat on the next two tracks
  5. 5. Chip holder – test open circuit 2 1. Place the two probes across the chip holder 2. Confirm open circuit 3. Repeat on the next two tracks
  6. 6. Wire – test short circuit 1. Place the two probes on the tracks with the wires 2. Check that the needle will swing towards the right
  7. 7. Wire – test open circuit 1. Place the two probes on adjacent tracks next to the wire track 2. Confirm open circuit
  8. 8. Visual checkGood: Solder on both sides of ALL pinsGood: No solder on the gut
  9. 9. Visual check Can improve: Partially not cover with solder Can improve: Solder on the gut
