2. Fume extractor (soldering) - Wikipedia

   en.wikipedia.org/wiki/Fume_extractor_(soldering)

   Fumes generated by soldering A woman at a bench working in front of a filtration system. A fume extractor is a device used to filter aerosolized chemical byproducts of the soldering process. [1] These devices take many forms depending on the project size and application, from small ductwork to entire fume hoods. [2]

3. Granulation (jewellery) - Wikipedia

   en.wikipedia.org/wiki/Granulation_(jewellery)

   There are three basic techniques that may be used to attach granules to a metal surface: hard soldering, fusing and colloidal soldering. The metals used in granulation are usually gold and/or silver alloys of high purity – alloys below 18 kt. gold and sterling silver being unsuitable. With each technique, the process begins with the making of ...

   [citation needed] The metal ions, more noble than aluminium, then undergo a redox reaction, dissolve the surface layer of aluminium and form a deposit there. This intermediate layer of another metal then can be wetted with a solder. One example of such flux is a composition of triethanolamine, fluoroboric acid, and cadmium fluoroborate. More ...

   Despite their similar appearance, a laminar flow cabinet should not to be confused with a fume hood. A laminar flow cabinet blows unfiltered exhaust air towards the worker and is not safe for work with pathogenic agents, [ 2 ] : 13 [ 3 ] while a fume hood maintains negative pressure with constant exhaust to protect the user, but does not ...

   On gold surfaces gold-indium intermetallics tend to be formed, and the joint then fails in the gold-depleted zone and the gold-rich intermetallic. [37] Less gold dissolution and more ductile than lead-tin alloys. [12] Good thermal fatigue properties. Pb 60 In 40: 195: 225 [16] Pb: No: In40. Low gold-leaching. Good thermal fatigue properties. Pb ...
