Question electrostatic

[gamer87]

Barefoot eliminates static electricity and can I work on the components? Do I handle the components barefoot or wearing a slipper do I need to buy any protection items?

Hi,

"Current flow" - even if small - will discharge ESD voltage.

If shoes prevent the current flow, then yes, barefoot can be a solution.
But if you have an isolating floor, then even barefoot can't cause enough current flow to reduce ESD voltage.

What equipments for protection you me recommend?

 

[KlausST]

Hi,

Simple, cheap, good working: Antistatic wrist strap.

Barefoot is not a solution, there are triboelectric
material-pairs with human skin which will develop
charge.

Barefoot does nothing for charged device body
or charged work surface. Against these even a
charge-neutral human body still represents an
ESD current source or sink, depending on the
companion element's charge.

There are well documented control methods.
Use as many as you can afford, or afford new
victims.

I usually work barefoot in contact with the ceramic floor but I don't have a grounding bar in the floor socket everywhere in the house to connect the bracelet

 

[wwfeldman]

ceramic floor is not conductive and will not help
is there a ground connection in the power outlets?

if your water supply comes from underground through a copper (or other metal)
pipe and there is no insulator (water meter, plastic pipe, water heater, etc),
then a cold water pipe may be a ground for the wrist strap

always check

 

[gamer87]

in the socket of my room it is grounded but it is far from the components table so it limits the use a lot

I thought that barefoot unloaded the statics someone before told me this information

without the grounding bar on the ground is there any other alternative to the bracelet that does not need the bar?

 

[wwfeldman]

the rod in the picture looks like it would be a good ground
what size if the wire?
can you run it to your components table and writs strap?

 

[gamer87]

I wish I didn't need that rod?

For a few years I was in the habit of touching a steel file cabinet beside my desk, just before picking up sensitive computer and electronics parts. I thought it ought to discharge static. A few times I sensed a mild spark go from my finger to the cabinet. I believe it acted as an electron reservoir of some kind. Although it was not grounded I gather it lost its change through the carpet due to dirt and humidity.

To detect static charge consider building this simple transistor detector.
