Placing a component the correct side up: * May affect heat dissipation. [Umm, that sounds like stretch, but who knows what designers think about?] * Allows reading the markings on those components that have markings, however cryptic the notation of

Chiakl Ion Chromatography has been perfectly described by Dave, but here are a couple of extra considerations: Ion Chromatography will tell you precisely what is present on the surface of your board/assembly but it will not tell you whether it will b
