IPC 610 General Terms questions and
answers
Cold Solder Connection ✔✔A solder connection that exhibits poor wetting and
that is
characterized by a grayish porous appearance.
Electrical Clearance ✔✔the minimum spacing between noncommon uninsulated
conductors.
High Voltage ✔✔will vary by design and application.
Intrusive Solder ✔✔An assembly soldering process that includes preform or solder
paste application for through-hole component leads, e.g., connectors, on the PCB.
Leaching ✔✔The loss or removal of a basis metal or coating during a soldering
operation.
Meniscus (Component) ✔✔Sealant or encapsulant on a lead, protruding from the
seating plane of the component.
Wire Diameter ✔✔is the overall diameter of conductor including insulation.
, Electrostatic Discharge (ESD) ✔✔is the rapid transfer of a static electric charge
from one object to another of a different potential that was created from
electrostatic sources.
Electrical Overstress (EOS) ✔✔is the internal result of an unwanted application of
electrical energy that results in damaged components.
Electrostatic Discharge Sensitive (ESDS) components ✔✔are those components
that are affected by these high-electrical energy surges.
The best ESD damage prevention ✔✔is a combination of preventing static charges
and eliminating static charges if they do occur.
The three types of protective enclosure material ✔✔(1) static shielding (or barrier
packaging), (2) antistatic, and (3) staticdissipative materials
Static shielding packaging ✔✔will prevent an electrostatic discharge from passing
through the package and into the assembly causing damage.
Antistatic (low charging) packaging materials ✔✔are used to provide inexpensive
cushioning and intermediate packaging for ESDS items.
Static dissipative materials ✔✔have enough conductivity to allow applied charges
to dissipate over the surface relieving hot spots of energy.
