How can ESD sensitive devices be damaged by ESD?

How can ESD sensitive devices be damaged by ESD?

Electrostatic Discharge (ESD) Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge, and can be damaged or destroyed by ESD. ESD damage can occur when there is a difference in charge between objects.

What damage can ESD cause?

Electrostatic discharge (ESD) occurs when a non-conducting surface is rubbed against another and the contacted surfaces are then parted. ESD can damage or destroy sensitive electronic components, erase or alter magnetic media, or set off explosions or fires in flammable environments.

How do you handle electrostatic sensitive devices?

Handling static-sensitive devices

  1. Limit your movement.
  2. Handle the device carefully, holding it by its edges or frame.
  3. Do not touch solder joints, pins, or exposed printed circuitry.
  4. Do not leave the device where others can handle and possibly damage the device.

Can static electricity cause damage?

Static electricity, also known as electrostatic discharge (ESD), is an electrical charge at rest, it builds and looks for somewhere to go. The discharge can cause three types of damage: catastrophic, latent and upset failure. Lightning is probably the most recognizable effect of static electricity.

What are the two types of damage that can be caused by ESD?


  • Catastrophic Failures.
  • Latent Defects.

What are the example of ESD sensitive devices?

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 does electrostatic discharge damage components?

How does ESD damage electronic circuitry? ESD is a tiny version of lightning. As the current dissipates through an object, it’s seeking a low impedance path to ground to equalize potentials. In most cases, ESD currents will travel to ground via the metal chassis frame of a device.

How do I stop static damage on my computer?

Here are some handy tips:

  1. Leave your PSU cable connected (but switch the unit off) to keep it grounded.
  2. Avoid rubbing oneself against carpeted flooring.
  3. Touch a metal part of the chassis itself prior to handling components.
  4. Work on a hard, solid surface.
  5. Use an ESD mat.

Can static destroy motherboard?

The motherboard is one of the most important parts of your computer — and also the most delicate. A single bump might damage the motherboard’s sensitive components. One static shock can permanently destroy a motherboard. If you handle your motherboard properly, though, you’ll avoid many potential problems.

Can static electricity damage a phone?

Static electricity usually is no more than bothersome, but it actually can be harmful. Computers, cell phones, photocopiers and other electronics can be damaged by static electricity.

How does humidity affect electrostatic discharge?

What Role Does Relative Humidity Play? Drier conditions tend to result in a higher risk of static electricity buildup, which can lead to electrostatic discharges. This is due to the fact that the air moisture content is a natural conductor, earthing any potential static charge.

What are the causes of electrostatic damage to electronic devices?

Per ESD Handbook ESD TR20.20 section 2.7 Device Damage – Types and Causes “Electrostatic damage to electronic devices can occur at any point, from the manufacture of the device to field service of systems. Damage results from handling the devices in uncontrolled surroundings or when poor ESD control practices are used.

What happens when you touch an electrostatic discharge sensitive device?

When a statically-charged person or object touches an electrostatic discharge sensitive (ESDS) device, there is a possibility that the electrostatic charge could be drained through sensitive circuitry in the device.

What is electrostatic voltage sensitivity (ESD)?

Many electronic components are sensitive to electrostatic voltage as low as 30 V and current as low as 0.001 A — far less than one can feel, hear or see (Table 1). Increasingly thinner layers in semiconductor devices have made ESD a growing threat. CMOS devices with small device geometries are particularly susceptible to failure.

How can we protect sensitive components from ESD damage?

There are two simple principles we can use to protect ESD sensitive components from ESD damage: a) Only handle sensitive components in an ESD Protected Area (EPA) under protected and controlled conditions b) Protect sensitive devices outside the EPA using ESD protective packaging
