What categories of damage ESD can cause in electronic devices?

What categories of damage ESD can cause in electronic devices?

TYPES OF ESD DEVICE DAMAGE

• Catastrophic Failures.
• Latent Defects.

What is electrostatic discharge what are the ways that it can damage electronic components?

ESD can cause harmful effects of importance in industry, including explosions in gas, fuel vapor and coal dust, as well as failure of solid state electronics components such as integrated circuits. These can suffer permanent damage when subjected to high voltages.

How many volts can damage an electronic component?

Static electricity can damage electronic equipment without the technician’s knowledge. The average person requires a static discharge of 3,000 volts before he or she feels it. An electronic component can be damaged with as little as 30 volts.

Which components are considered Esds?

Common electrostatic-sensitive devices include:

• MOSFET transistors, used to make integrated circuits (ICs)
• CMOS ICs (chips), integrated circuits built with MOSFETs. Examples are computer CPUs, graphics ICs.
• Computer cards.
• TTL chips.
• Laser diodes.
• Blue light-emitting diodes (LEDs)
• High precision resistors.

How do you check for static discharge?

There are at least three instruments we can use to measuring static: electrostatic fieldmeters, Coulomb meters used with Faraday cups, and non-contacting electrostatic voltmeters. The only meter that actually measures charge is the Coulomb meter.

How are electronics more sensitive to the effects of ESD?

With the trend to miniaturisation individual electronics components are becoming much smaller. This makes them more sensitive to the effects of damage from ESD. The effects of electrostatic discharge, ESD, are dependent on a large number of variables. Most of these are difficult to quantify.

Where is ESD testing done on a microchip?

ESD testing is done at various levels in a product cycle, such as at the component level (for example, Microchip’s MCU), at the board level (such as control board) and at the end equipment level (such as a washing machine).

When does an ESD event cause EOS damage?

ESD events that cause damage, or weaken the device, making it more susceptible to future EOS events. 9. Latch-up events may result in EOS damage if the current is high or if it persists for an extended period of time.  2014 Microchip Technology Inc. DS00001785A-page 3

What are the effects of electrostatic discharge ( ESD )?

ESD, electrostatic discharge affects electronic components in a number of different ways. The large static voltages can enter devices and cause damage to the intricate internal circuitry.
