How can we prevent esd

For example, if you have a system that runs off 6 volts and you push 25, volts through it there could be damage. This may cause an oxide failure that damages the circuitry, the metal to melt, or even cause connections aka junctions to breakdown.

When manufacturing and assembling electronics, it is important to take precautions at each step of the process to prevent any ESD events to occur before the part is fully assembled and ready to be shipped to the customer. Here at Xymox we have several preventive measures in place:. Air conditioning can pull moisture out of the air, causing a greater risk for electrostatic discharges. Air moisture is a natural conductor, so it can absorb and distribute the excess charge.

When moisture is pulled out of the air, objects are more likely to hold charges which increases the risk for ESD events to occur. If no grounding strap is available, touch the exposed, bare metal of the device to ground yourself before handling the component. Avoid contact between the component that is subject to ESD damage and your clothing.

ESD voltages emitted from clothing can damage components. When removing or installing a component that is subject to ESD damage, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an antistatic bag see Figure 1.

If you are returning a component, place it in an antistatic bag before packing it. To dissipate this charge, always ground the cables to a suitable and safe earth ground before connecting them to the system. Help us improve your experience. For sensitive or critical electronics applications, such as implantable medical devices or avionics, failure at this phase can have severe repercussions. The best way to prevent electrostatic discharge is by stopping potential from building in the first place.

In addition to following these guidelines, consider investing in equipment which is helpful for reducing electrostatic discharge. Three primary pieces of equipment are necessary to prevent electrostatic discharge during manufacturing:.

Electrostatic wrist and heel straps are simple, inexpensive devices your operators should wear while working on or near electronic manufacturing. These antistatic devices work to continuously ground the person wearing them. In other words, they prevent electrostatic discharge by stopping an electric charge from ever building up. Another piece of equipment for preventing ESD is the anti-static floor mat. These mats work to stop electricity from building up in workers from contact with the floor.

In plants with particularly sensitive electronics or floors with high static potential, these mats become an essential addition. Manufacturing electronics is a careful business. The circuit boards and assemblies created are delicate, requiring precise control during manufacturing and the use of protective safeguards.

As such, it is critical that manufacturers follow best practices and employ special equipment to prevent ESD. Skip to content. Speak with an application engineer today!
