You need to remove the oxide before you can properly solder your [or any] component. Call your flux supplier ask them for a more active flux than you are using and for their recommendations on removing the flux residues.

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

ROSA is your answer. Contact Greg Wood at the American Competitiveness Institute in Philadelphia for details. Here is his email: gwood@aciusa.org Store your parts in Static Intercept bags to eliminate any future oxidation. http://www.staticintercep

COULD SOMEONE PLEASE TELL ME OF A WAY TO CLEAN THE OXIDIZATION OF OF WHITE TIN PADS, I AM GETTING ALOT OF DEWETTING PROBLEMS. AND I CONCLUDED THAT ALL THE BOARDS WITH WHITE TIN ARE HAVING THE SAME PROBLEMS. THANKS FOR THE INPUT.

Does anyone out there know of a method to remove oxidation from the balls of a BGA, other than reball. thanks, MRMAINT

Could be lots of things. With limited information about temperatures, solder alloy, and cleaning; we'll swing for the fence that you got these solder connections very hot. So hot that Pb oxide is dominating the solder joint surface instead of the

What rubber had or the liquid medicines spreads has been possible to guard against the oxidation?

Does anybody know how could I clean pcbs with immersion silver finising ? I have several boards that got oxidized for having been waiting too long to be processed after opening the package.

the flux in the solder paste should take care of the oxides. if possible print a board and run thru reflow to check for wetting issues......there are some published papers that say that the tarnish layer is too small to create any wetting issues or o
