Do you need an anti-static wristband when you’re building a PC?

Many PC building manuals advise the usage of an anti-static wrist strap earlier than you begin assembling the PC. And an anti-static wrist strap is cheap and simple to make use of. But is it actually crucial? Let’s discover.

The anti-static wristband exists for a similar motive your hair stands up when you rub a balloon in opposition to it, or a sweater feels humorous when it has simply been faraway from the garments dryer—static electrical energy. Static electrical energy is innocent more often than not, but when you are electrically charged and contact one thing conductive, you go that cost on.

If you contact steel, you go the electrical energy to the steel. And if you contact naked electronics whereas you are charged, you switch it to the electronics and trigger an electrostatic discharge, or ESD.

For this motive, elements equivalent to motherboards or graphics playing cards are provided in “anti-static bags”—shimmering grey plastic baggage that kind a Faraday cage across the part to guard in opposition to ESD.

To use an anti-static wristband, you put the band round your wrist. Connect the cable and fix the steel clip to a grounded and unpainted steel floor.

The wristband should even be earthed earlier than beginning work. To guarantee this, contact it to the bottom. This permits the static electrical energy to move out of you, via the bracelet and into the bottom. There it will likely be absorbed. And you can rule out any electrical energy you could also be carrying being transferred to the circuit boards you are about to the touch.
