I have a question (s) on ESD- all related to use of wood in a typical
PCB Assembly line:

1. How a wooden mini stool if used for holding tote box ( card board
with static protecive coat, black color) can affect static sensitive
devices inside the tote box / shipping tubes/bags/ PCB assemblies
parially bilt ? The wooden stool sits besides operators seat and
operator is wearing wrist strap and attached to grounded table. The
point of contension is : Wooden mini-table is coated with enamel paint.
What kind of mini table / stool is used in general ?
2. To manual assembly, if woodem slide is used , can it affect
components being hand inserted ? Wood is varnished but no enamel paint
on this ?
3.For spot cleaning, if brushes with wooden handles are used ? What if
bristles of brush are made of Nylon/plastic material ? - Assumption is
that brush is soaked in solvent ISO-Propyl when used for cleaning.

4.For storage of Tape feeders on wooden stands -Partially used tapes
carrying components on tape feeders. Can a wooden feeder stands affect ?

It might appear 4 questions in one, I will appreciate answers toching
all aspects as mentioned above. Thanks in advance.
