1. Description:

To attach a bias connector, follow these steps:

2. Steps:

• If you have run out of bias connectors, Natalia Kuznetsova or Anton Eppich can make some more.
• Before using the bias connector, test all the wires for opens.
• Make sure there are clean plastic covers and rails on both sides. For the plastic covers use 6-32 x 3/16 Button Head Cap Screws...try to use the screws that have a round top.
• Gently push the bias connector in place. Make sure when the Z-side is up, the first pin from the left has a black wire connected to it, as shown on the picture represented. Attach a connector cover that found in a clear plastic box labeled Universal Parts Layer 1 or Layer 2 in brown cabinet. Use a 4-40 x 1/4 Flat Head Cap Screw.
• Bend the wires for each side to understand how they fit in between the G-10 and Ringframe. The Z-side uses Black and Purple wires and the Phi-side uses Red and Orange wires.
• For the Z-side; The black wire from the 1st pin goes to the bias connector that is the rectangular gold pad closest to the wafers.
• The purple wire the 9th pin goes to the guard ring connector that is the rectangular gold pad closest to you.
• Check the upilex to make sure the connectors are not shorted together. Sometimes there is a strip of gold that did not get trimmed off the upilex and causes the bias and guard ring to short together. If you can see this strip take scalpel and carefully cut it gold strip.
• Use superglue gel and or tape to hold wires in place before attaching wires.
• Bend wires to fit along the side of upilex. (I usually tape the wires down to the G-10 to make sure they are long enough and bend in the correct place before gluing them to the G-10.)
• When you have the wires adjusted to their correct lengths strip the ends that get connected to the gold pads.
• Follow the same directions for the Phi-side.
• The red wire from the 2nd pin goes to bias connector that is the rectangular gold pad closest to the wafers.
• The orange wire from the 10th pin goes to the guard ring connector that is the rectangular gold pad closest to you.
• Check upilex to make sure the connectors are not shorted.
• After you have glued down the wires on both sides, use conductive silver epoxy to attach wires to the connectors.
• Turn oven on and place Detector in the oven overnight.
• Check the connection of each connector with a multimeter.
• After you are done, enter the corresponding entry into the DFA production database!
