|Destructive Physical Analysis (DPA)
||Destructive Physical Analysis (DPA)
||A process of determination of device construction or failure modes.
||Dewetting is a condition that results when molten solder coats a surface and then recedes to leave irregularly-shaped mounds of solder that are separated by areas that are covered with a thin film of solder and with the basis metal not exposed.
|Disturbed solder connection
||Disturbed solder connection
||A solder connection that is characterized by the appearance that there was motion between the metals being joined when the solder was solidifying.
||A condition of a ball grid array (BGA) package after reflow where the corners turn down and toward the printed board laminate surface. This condition in the worse case causes the balls on the outside row to be in compression and the balls in the center to be in tension. (Opposite of "Cupping (BGA).")
|Dual-Inline Package (DIP)
||Dual-Inline Package (DIP)
||An electronic device package with a rectangular housing and two parallel rows of electrical connecting pins, usually protruding from the longer sides of the package and bent downward.
|ESD - Protected Area (EPA)
||ESD - Protected Area (EPA)
||ESD Protected Areа is a workplace or area that provides protection against damage due to ESD.
||The shortest distance between two conductors, which includes traces, terminals and structures, measured through air.
|Electromagnetic Compatibility (EMC)
||Electromagnetic Compatibility (EMC)
||A device's ability to function properly in its operating environment without causing electromagnetic interference to other equipment, or itself being susceptible to external interference.
|Electrostatic Discharge (ESD)
||Electrostatic Discharge (ESD)
||The rapid spontaneous transfer of electrostatic charge, induced by a high electrostatic field.
|Electrostatic Discharge Sensitive devices (ESDS)
||Electrostatic Discharge Sensitive devices (ESDS)
||An electrostatic-sensitive device is any electrical component which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors.
