How Clean Is Clean?

Over the past several years, post-reflow defluxing of circuit assemblies has gained in popularity. Microminiaturization of components and boards, combined with higher expected reliability and increased product liability, have contributed to the prominence of defluxing. Lead-free solder paste - with its higher reflow temperatures and negative effects on flux - increase the likelihood of post-reflow defluxing to increase a product�s reliability and aesthetic appearance.

Best, Inc instructors have put to video demonstrations of common hand soldering skills.

Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
