| {{w|Solder}} is a metal alloy with a low melting temperature (typically around 360°C, but in special cases melting points between 90°C and 450°C or above are available), used to bond electronic components together permanently. Most solder materials are quite ductile so it might be too easy for the forces a connector is subject to to permanently change their shape. Along with the fact that the resistance of solder is typically way higher than that for copper the pin under heavy electrical stress could overheat and melt, thus bonding the connector to its receptacle, and thereby "trapping" the receptacle. Additionally putting a pin that might slightly change their shape directly next to a high voltage pin means risking accidentally connecting two power rails with entirely different voltages together (causing an overvoltage in the lower-voltage rail that is likely to break the circuit, as has happened with some Apple devices). In this case the +120V AC pin might be able to deliver enough power to actually fuse the solder-only pin. This could also be a reference to increasing publicity around the fields of electronics security: hobby reverse engineers have been finding ways for some time now to evade the blown fuses in microcircuitry preventing them from being reprogrammed, using glitching techniques. | | {{w|Solder}} is a metal alloy with a low melting temperature (typically around 360°C, but in special cases melting points between 90°C and 450°C or above are available), used to bond electronic components together permanently.
