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. Flux (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Flux_(metallurgy)

   The fumes liberated during soldering have adverse health effects, and volatile organic compounds can be outgassed during processing; The solvents required for post-soldering cleaning of the boards are expensive and may have adverse environmental impact; In special cases the drawbacks are sufficiently serious to warrant using fluxless techniques.

4. Bore evacuator - Wikipedia

   en.wikipedia.org/wiki/Bore_evacuator

   The system may be arranged to allow the gases to escape through the forward set of holes before the shell reaches it, causing a partial vacuum to develop directly behind the shell, aiding extraction. [2] For best results, the breech must be opened at the proper time, just as the forward momentum of the gases reaches its maximum, the peak flow.

5. Dust collector - Wikipedia

   en.wikipedia.org/wiki/Dust_collector

   A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.

6. Materials for use in vacuum - Wikipedia

   en.wikipedia.org/wiki/Materials_for_use_in_vacuum

   A better choice for vacuum systems is the tin-silver eutectic, Sn95Ag5 (Sn-Ag eutectic is actually 96.5-3.5); its melting point of 230 °C (446 °F) allows bakeout up to 200 °C (392 °F). A similar 95-5 alloy, Sn95Sb5, is unsuitable as antimony has similar vapor pressure as lead. Take care to remove flux residues.

7. Vapor barrier - Wikipedia

   Sensors installed to a fixture to check selective solder machine parameters Selective soldering machine. Selective soldering is the process of selectively soldering components to printed circuit boards and molded modules that could be damaged by the heat of a reflow oven or wave soldering in a traditional surface-mount technology (SMT) or through-hole technology assembly processes.
