2. 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.

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 ...

4. Filler metal - Wikipedia

   en.wikipedia.org/wiki/Filler_metal

   Brazing and hard soldering use a higher temperature filler that melts at a temperature which may approach that of the base metal, and which may form a eutectic alloy with the base metal. Filler alloys have a lower melting point than the base metal, so that the joint may be made by bringing the whole assembly up to temperature without everything ...

5. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point.

6. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   "Hard soldering" or "silver soldering" is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint. Extra-easy solder contains 56% silver and has a melting point of 618 °C (1,145 °F ...

7. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Marginal wetting. Good for step soldering. Used for soldering stainless steel as it wets stainless steel better than other soft solders. Silver content does not suppress dissolution of silver metallizations. [56] High tin content allows absorbing significant amount of gold without embrittlement. [73] Sn 96 Ag 4: 221: 229: Yes: No: ASTM96TS ...
