I am looking to apply 10-15�m of a conductive material that will withstand 280�C. Our product consists of an alumina substrate sputtered with NiCr (2000�) and Copper (2000�) and 15-60 �m of electroplated copper (all metals patterned on the substrae)

I have a few questions regarding Solder products being UL Listed or Recognized. I am aware that UL does test solder material (conductive material) using the UL 746 standard. However, i would like to know if UL actually recognizes the conductive mater

Looking for any reliability data on aqueous flux residue causing low Z defects, specifically any data that may illustrate life expectancy under any humidity/temp environment. How long it takes for conductive material to migrate and form low Z impedan

Does the thermal conductivity of a copper trace on a printed circuit board change as the copper oxidizes? Is the oxide on copper a thermal insulator? If so, should it be considered in an analysis of thermal resitivity between a ground plane and a h

In theory, no clean flux residues are electrically benign...period. Here's a good test. Subject the board to some moisture/humidity, and have your circuit designer ohm-out any areas that may be affected by conductive material. Option B: Have a la

Hi Steve ... There are arguments between fabricators and thermal relievers about adding non-connected copper tabs to barrels in hopes of providing thermal relief, but that's not what you're talking about, I believe. I don't foresee an issue moving t
