2. Rework (electronics) - Wikipedia

   en.wikipedia.org/wiki/Rework_(electronics)

   X-ray picture of inadequate solder joints. Rework is practiced in many kinds of manufacturing when defective products are found. [2] For electronics, defects may include: Poor solder joints because of faulty assembly or thermal cycling. Solder bridges—unwanted drops of solder that connect points that should be isolated from each other.

3. Head-in-pillow defect - Wikipedia

   en.wikipedia.org/wiki/Head-in-pillow_defect

   In the assembly of integrated circuit packages to printed circuit boards, a head-in-pillow defect (HIP or HNP), also called ball-and-socket, [1] is a failure of the soldering process. For example, in the case of a ball grid array (BGA) package, the pre-deposited solder ball on the package and the solder paste applied to the circuit board may ...

   en.wikipedia.org/wiki/Dye-and-Pry

   Dye-n-Pry is a useful failure analysis technique to detect cracking or open circuits in BGA solder joints. [2] This has some practical advantages over other destructive techniques, such as cross sectioning, as it can inspect a full ball grid array which may consist of hundreds of solder joints. Cross sectioning, on the other hand, may only be ...

   A typical spring-loaded solder sucker A solder sucker partially dismantled showing the spring. A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. [1]

6. Piping and plumbing fitting - Wikipedia

   The joint is then heated, typically by using a propane or MAPP gas torch, although electrically heated soldering tools are sometimes used. Once the fitting and pipe have reached sufficient temperature, solder is applied to the heated joint, and the molten solder is drawn into the joint by capillary action as the flux vaporizes. "Sweating" is a ...
