Anti-static stuff to assemble K3.

Hello all,

like I have wrote previously, I will assemble my K3 at April next year,
however I have not anti-static stuff yet, I have found site that sells
anti-static stuff, like mats, gloves and ESD wrist strap. Could be
useful to buy all stuff, even that ESD gloves to assemble K3 ?

Here is the site:

http://www.leiritronica.com/electronica/index.php?cPath=139_147

Sorry, it is in portuguese language, but stuff is pretty visible.

Best regards and till next email.

David,

The mat and wrist strap should do the job nicely, but I don't believe
the gloves are necessary. You will be dealing with parts at the board
level and not handling particularly sensitive individual components.

Re: Anti-static stuff to assemble K3.

Hello all,

tks for your replay emails and best regards.

Ok I will not buy gloves according to your opinions, I will safe some
money :) , however I have another doubt:
at my apartment I have not a central earth connection, but some
electricity plugs (mainly from kitchen) have the earth cable attached to
plugs (of course not in same position of 220 Volts :) ), could I attach
terminals from mat and wrist strap to that earth connection from
electricity plugs ???

Best regards and till next email.

Hi David and all,

Quick reminder about anti-static stuff.
Your pad and hand-strap must NEVER be connected directly to the ground.
Between those and the ground a resistor of 1 mega ohm must be inserted.
See on the picture below, a yellow adapter (plugged) containing this
resistor.

Tks for your pic, however that hand-strap, that I have sent website, has
a resistor of 1 mega ohm inserted. So I need to pay attention to mat
because has not that resistor.

Actually David, your ESD dissipative mat *should* be connected directly to
ground. The 1 Meg resistor is contained somewhere within the ESD wrist
strap assembly.

According with picture from website it appears that mat has not a 1 Meg
resistor like ESD wrist strap, tks for information Gary.

The EDS mat that I have has the same snap connector as the wrist strap and it has the 1 Meg ohm resistor built in.
