i also notice the carbon and oxygen is high on the defect? Why is that?

Looks like you have a carbon black process that isn't quite plating to completion, pin prick size holes have remained in the plating. When dipped in an etchant (ie any acid or H2O) the holes grow and they leak carbon. This may be more of a problem th

Sure they'll do it...If you're willing to pay double or triple the cost. It might not be as easy as you think. the value is usually marked in white over the black carbon area that actually is the resistor. Underneath is just the white ceramic carr

From my experience, we have had little success in reworking boards with the black pad condition. In one instance, with several reworks, we were able to get plated through holes with the defect to take solder but the joint reliability was highly ques

Can't be 100% sure now, but Xerox used to be proud that recycled photocopier toner was used in the process of making black plastic bags. Toner was full of tiny magnetic particles that were attracted to the electrostatic image transfered from the c

there is another product on the market, it is nitrile Based, 100% silicone free, but the stuff ain't cheap Mcgee! an 18x18 piece of carbon black silicone will set you back $125.00, the nitrile is x4 that and that's before the NRE. Have you consider

More and more PCB fabs are switching from chemical copper to what is called a "black hole" process from McDermitt.In this process a very thin layer of carbon is put on the base material instead of chemical copper. Can anyone tell me about the advanta
