Here are the answers to your questions. 1. Yes, some increase conductivity when the approach the end of their shelf life. 2. Yes, the manufacturer as well as the type. 3. Try burning off more of the flux in your preheat. 4. Yes, especially for QA.

We have just been audited by our customer. One of the major finding was the thermocouple attachment. They insist that we use conductive epoxy to attach the thermocouple to the IC body and PCB surface. Any suggestion on what brand/model of conducti

Conductive epoxy is usually specified as less than 6:1 aspect ratio fill capable, while non-conductives are 10 to 14:1 (depends on which brand and who you ask).

We're aware of no such standard. Check with ink suppliers [eg, Conductive Compounds, Coats Circuit Products, Creative Materials, etc] to confirm.

Dave, Do you know if such thermal transfer study with CB-100 (or equivalent) is available for review? My customer is pursuing this option and I am curious on how much improvement I would see by specifying a conductive via fill on the board. Rgds, P

As you move, your clothing is rubbing against your body causing static to build up in the material. Since the material is a poor conductor, not all of the charge gets conducted through your skin to the heel straps. The smock is designed to prevent th
