What does ESD stand for? ElectroStatic Discharge Electronic Sensitive Device Every Static Dismissed Non of these options Every Single Digit.
How do we generate static charges? (If we are not equipped with ESD protection) Walking over carpet Use ofpackaging tape / scotch tape Use of Styrofoam packaging material Wearing synthetic clothes Using plastic drinking bottles Handling stainless steel screws.
Most of us experienced static discharges, e.g. touching a metallic handle. What did you maybe feel? I got an small electrical shock and felt it I heard a discharge arc like a small zapping noise I passed out I heard x-mas bell ringing.
What is ESD Class 0? Damage you can't feel. Voltages between 0-199 Volt Damage you can't feel. Voltages between 200-1999 Volt Damage you might feel. Voltages between 2000-3999 Volt Damage you can probably hear and see and detect as spark with your own body. Voltages between 4000-15999 Volt Voltages you feel above 16000V.
What is ESD Class 1? Damage you can't feel. Voltages between 200-1999 Volt Damage you can't feel. Voltages between 0-199 Volt Damage you might feel. Voltages between 2000-3999 Volt Damage you can probably hear and see and detect as spark with your own body. Voltages between 4000-15999 Volt Voltages you feel above 16000V.
What is ESD Class 2? Damage you may feel. Voltages between 2000-3999 Volt Damage you can't feel. Voltages between 0-199 Volt Damage you can't feel. VVoltages between 200-1999 Volt Damage you can probably hear and see and detect as spark with your own body. Voltages between 4000-15999 Volt Voltages you feel above 16000V.
What is ESD Class 3? Damage you can probably hear and see and detect as spark with your own body. Voltages between 4000-15999 Volt Damage you may feel. Voltages between 2000-3999 Volt Damage you can't feel. VVoltages between 200-1999 Volt Damage you can't feel. Voltages between 0-199 Volt Voltages you feel above 16000V.
Which typical Voltage you can generate when you walk over a carpet? 1500 - 35000 Volt 250 - 12000 Volt 600 - 7000 Volt 700 - 6000 Volt 9000 - 15000 Volt.
Which typical Voltage you can generate when you walk over untreated vinyl floor? 250 - 12000 Volt 1500 - 35000 Volt 600 - 7000 Volt 700 - 6000 Volt 9000 - 15000 Volt.
Which typical Voltage you can generate when you use a vinyl non ESD envelope for work instructions? 600 - 7000 Volt 1500 - 35000 Volt 700 - 6000 Volt 250 - 12000 Volt 9000 - 15000 Volt.
Which typical Voltage you can generate when you work at your bench? 700 - 6000 Volt 1500 - 35000 Volt 600 - 7000 Volt 250 - 12000 Volt 9000 - 15000 Volt.
Which typical Voltage you can generate when you unwind regular scotch tape? 9000 - 15000 Volt 1500 - 35000 Volt 600 - 7000 Volt 250 - 12000 Volt 700 - 6000 Volt.
A latent defect is a defect we mostly can't detect in inspection and testing a defect we can directly measure Is like a sick person with lower performance Is a catastropic failure Could change to a catastrophic failure after a certain period of time. (Upsets customer).
Newest micro processor components can be damaged at 30 Volt or less 1500 - 35000 Volt 250 - 12000 Volt 600 - 7000 Volt 700 - 6000 Volt.
Why we should care about ESD? Life's are at risk! (We produce products for use in explosive environments!) We shouldn't, our products are safe No need, when they fail we just replace them for free or charge the customer We can't take care about everything Our QA Director say so Our equipment is expensive and when our customer has a problem they can't finish the job . It is very expensive event and very disturbing for our customers!.
APS ESD rules, how many do we have? 5 ESD Rules 4 ESD Rules 3 ESD Rules 2 ESD Rules 1 ESD Rules No ESD Rules.
What is APS ESD rule #1? Wear an ESD smock behind the yellow lines at all times. (At least 3 buttons closed) Stay within walking area when you don't wear an ESD smock Wear an ESD smock behind the yellow lines at all times. (buttons open) You can walk wherever you want.
What is APS ESD rule #2? Use always shielded and folded ESD bags for storing and carrying ESD sensitive material! You can carry all material unprotected Use always normal zip lock bags for storing and carrying ESD sensitive material Don't worry, I can handle this without protection.
What is APS ESD rule #3? Use black conductive ESD totes when carrying more electronics or finished products. Use lids if products are not in an shielded ESD bag You can carry all material unprotected Use always normal zip lock bags for storing and carrying ESD sensitive material I can carry the parts how i want it.
What is APS ESD rule #5? Keep my workplace clean! Keep static generators at least 2 feet away! If I use a smock, then I don't need to use the wrist strap! I have slippers on, I don't need a wrist strap I never had an ESD issue so I don't need to care.
What is APS ESD rule #4? Attach your wrist strap before and when working with ESD sensitive components at all times! Unpack after I'm strapped! If I use a smock, then I don't need to use the wrist strap! I have slippers on, I don't need a wrist strap I never had an ESD issue so I don't need to care.
Who do you inform if your ESD equipment is not working? Your Supervisor The QA Guys Fire Department NSA.
The IC industry estimated ESD failures are around xx% of all undetected failures. How much is it approx.? approx. 30% 1-5% 10% 20% Less than 1% 50%.
Why we should be careful? IC's become smaller and smaller and ESD levels are dropping down over the next years We can prevent unhappy customers We can avoid financial losses We will be the preferred supplier for the industry Life's are at risk when using our products! (Explosion environment) It's better to sell new stuff than getting warranty repairs back.
