Hello Technet: Does anyone have any knowledge regarding solder dross contamination in otherwise properly formed solder joints? The joints were formed in a wave solderer and exhibit dross contamination roughly .005" - .010" in diameter. The joints seem to have proper "meniscus" and are mostly "shiny", but are dull around the entrapped dross. Is this purely cosmetic or does it present a potential solder joint problem?
