2. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   Solder paste is used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through-hole pin in paste components by printing solder paste in and over the holes. The sticky paste temporarily holds components in place; the board is then heated, melting the paste and ...

3. Stencil printing - Wikipedia

   en.wikipedia.org/wiki/Stencil_Printing

   Insufficient solder paste may cause poor bonds and contact between components and the board. The common causes of insufficient solder paste are poor gasketing, clogged stencil apertures, insufficient solder paste bead size, paste/stencil being used beyond recommended life span, stencil not wiped clean, or low squeegee pressure.

4. Jewellery cleaning - Wikipedia

   en.wikipedia.org/wiki/Jewellery_cleaning

   The cleaner would first inspect the jewelry to ensure that the gemstones are accounted for and secured. Materials that can handle it are often placed in an ultrasonic bath using a cleaning solution and later put through a steam cleaner, while more sensitive materials will go through light brushing in soapy water.

5. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Reflow soldering is a process in which a solder paste (a mixture of prealloyed solder powder and a flux-vehicle that has a peanut butter-like consistency [8]) is used to stick the components to their attachment pads, after which the assembly is heated by an infrared lamp, a hot air pencil, or, more commonly, by passing it through a carefully ...

6. Squeegee - Wikipedia

   en.wikipedia.org/wiki/Squeegee

   A squeegee or squilgee is a tool with a flat, smooth rubber blade, used to remove or control the flow of liquid on a flat surface. It is used for cleaning and in printing. The earliest written references to squeegees date from the mid-18th century and concern deck-cleaning tools, some with leather rather than rubber blades.

7. Diamond tool - Wikipedia

   en.wikipedia.org/wiki/Diamond_tool

   High-temperature brazed diamond tools: This tool is made by brazing a single layer of diamonds onto the tool via a solder at a temperature of over 900 °C. using vacuum brazing or atmosphere-protected brazing. This tool has several advantages: the solder can hold the diamonds very firmly, the single layer of diamonds' exposed height can be 70% ...

8. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Easy solder is also often used for repair work for the same reason. Flux is also used to prevent joints from desoldering. Silver solder is also used in manufacturing to join metal parts that cannot be welded. The alloys used for these purposes contain a high proportion of silver (up to 40%), and may also contain cadmium.

9. 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 ...
