IPC-A-610H 3 Handling Electronic
Assemblies Exam Questions and
Answers
Which Appendix does Section 3 reference? - Answer -Appendix B
Where is IPC-A-610H EOS/ESD and Handling information located? - Answer -Appendix
B
ESD - Answer -Electrostatic Discharge;
rapid transfer of a static electric charge from one object to another
ESDS - Answer -Electrostatic Discharge Sensitive;
describes components and assemblies highly susceptible to damage by ESD
(Electrostatic Discharge)
Must physical contact occur to for ESD damage to happen? - Answer -No;
damage can occur at close proximities even without physical contact
True or False
Failure due to ESD damage occurs immediately. - Answer -False;
failure can be immediate *or* latent
Electrical Overstress (EOS) - Answer -damage caused by unwanted introduction of
electrical energy during test or other processing;
cannot be prevented by ESD controls
ESD - protected area (EPA) - Answer -area in which ESDS can be handled with
accepted reduced risk of damage as a result of electrostatic discharge or fields;
*ESDS parts and assemblies must be packaged in ESD protective enclosures when
removed from these areas!*
static mats - Answer -ESD protective worksurfaces;
*should* have <1X10^9 Ohms resistance and kept clean to prevent buildup of insulative
layers
Requirements for seated workstations - Answer -wrist strap and cord with resistance
<3.5x10^7 Ohms resistance
