2. Reactive multi-layer foil - Wikipedia

   en.wikipedia.org/wiki/Reactive_multi-layer_foil

   The foil can be used as a pyrotechnic heat source, a replacement of potassium chlorate/iron pellets, for thermal batteries. It reacts faster than the conventional composition, reaches higher temperatures, and heat buffers of inert metal (e.g. steel) are needed to lower the peak temperature and prolong the heat delivery.

3. Ultrasonic soldering - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_soldering

   Ultrasonic soldering (U/S soldering) is a flux-less soldering process that uses ultrasonic energy, without the need for chemicals to solder materials, such as glass, ceramics, and composites, hard to solder metals and other sensitive components which cannot be soldered using conventional means.

4. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Soldering (US: / ˈ s ɒ d ər ɪ ŋ /; UK: / ˈ s oʊ l d ər ɪ ŋ /) is a process of joining two metal surfaces together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong and durable joint.

5. Glass-to-metal seal - Wikipedia

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

6. Solderability - Wikipedia

   en.wikipedia.org/wiki/Solderability

   Both quantitative and qualitative tests for solderability exist. [6] The two most common testing methods are the 'dip and look' method and wetting balance analysis.In both of these tests, the soldered pieces undergo an accelerated aging process before being tested for solderability, to take into consideration the time a component was in storage prior to mounting to final assembly.

7. Diffusion bonding - Wikipedia

   en.wikipedia.org/wiki/Diffusion_bonding

   Multiple sheets are stacked atop one another and bonded in specific sections. The stack is then placed into a mold and gas pressure expands the sheets to fill the mold. This is often done using titanium or aluminum alloys for parts needed in the aerospace industry. [15] Typical materials that are welded include titanium, beryllium, and zirconium.

8. Space blanket - Wikipedia

   en.wikipedia.org/wiki/Space_blanket

   layering materials of emergency blanket 32 layers are 0.45mm thick. First developed by NASA ' s Marshall Space Flight Center in 1964 for the US space program, [2] [3] [4] the material comprises a thin sheet of plastic (often PET film) that is coated with a metallic, reflecting agent, making it metallized polyethylene terephthalate (MPET) that is usually gold or silver in color, which reflects ...

9. Fusible alloy - Wikipedia

   en.wikipedia.org/wiki/Fusible_alloy

   Lies between soft solder and silver brazing alloys, thereby avoiding damage to critical electronics and substrate deformation and segregation. Best solder for Aluminum wire to Copper busses or Copper wire to Aluminum busses or contacts. [19] UNS#: L91090 Sn 92.0, Zn 8.0: 199 °C (390 °F) no: Tin foil: Sn 100: 231.9 °C (449.4 °F) (yes) Sn99 ...
