2. Rework (electronics) - Wikipedia

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

   After fabrication of the BGA package, tiny balls of solder are glued to the pads on its underside; during assembly the balled package is placed on the PCB and heated to melt the solder and, all being well, to connect each pad on the device to its mate on the PCB without any extraneous solder bridging between adjacent pads. Bad connections ...

3. 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.

4. Failure of electronic components - Wikipedia

   en.wikipedia.org/wiki/Failure_of_electronic...

   Severe PCB corrosion from a leaky PCB mounted Ni-Cd battery. Printed circuit boards (PCBs) are vulnerable to environmental influences; for example, the traces are corrosion-prone and may be improperly etched leaving partial shorts, while the vias may be insufficiently plated through or filled with solder. The traces may crack under mechanical ...

5. Head-in-pillow defect - Wikipedia

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

   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 both melt, but the melted solder does not join. A cross-section through the failed joint shows a distinct boundary between the solder ball on the part and the solder paste on the circuit ...

8. Point-to-point construction - Wikipedia

   en.wikipedia.org/wiki/Point-to-point_construction

   Solder makes a strong electrical and mechanical connection. Point-to-point wiring is not suitable for automated assembly (though see wire wrap , a similar method that is) and is carried out manually, making it both more expensive and more susceptible to wiring errors than PCBs, as connections are determined by the person doing assembly rather ...
