A number of years ago I reviewed this problem within our plants.
I totally agree with Dean that constant monitoring is the way to go. If you
want to get really high compliance, then hook the constant monitors up to a
network interface and start sending operators automatic emails if the ratio
of their connected time to their total time-in-plant appears out-of-whack!
In order to not be viewed as a dark overlord, in any case you should provide
the times automatically to the workers as a service to help them fill out
their time sheets correctly.

Nah.
The solution already exists! The problem is, none of you are using it.
The Constant Monitoring systems used in Tier 4 companies for the wrist
straps are easily expanded to ESD flooring in and around the assembly areas
where the components are usually outside of their Faraday packaging.
Constant monitors can be set up to go through the operator to the floor
ground in the immediate area. So if the operator has a faulty shoe ground OR
a faulty wrist strap ground, every time they touch the equipment it checks
the resistance and beeps if it is out of range.

I think disabling the machines directly would be hard to setup the software
to "talk" between your ESD tester and the machine directly.
An alternate would be to use your ERP system linked to the work order
operation for the SMT line to the passing ESD testing. So the technician
could not log into the work order operation without first passing ESD
testing.
Our ERP system handles the ESD test results and would venture that it would
be easier to create software links to the WO operations.
BTW, this is an excellent idea to error-proof your process, especially when
escapes are possible. If the is a way to take a shortcut, there always seem
to be a will to take shortcuts by some of your staff.

All,
Has anyone seen or know of a control system that prevents an operator from
running an SMT line if they did not pass or go through an ESD test. (i.e.
ESD shoe check)?
Let me give you the scenario we are considering. Operators go through one
entrance that requires them to check their ESD compliant shoes and if the
test is good, they would walk through a turnstile that is linked to the ESD
tester. Our operators have bar- coded badges that would identify them. We
also have other entrances/exits to the SMT area that are required for safety
reasons. If an operator decides to enter the room without going through the
ESD check entrance, once the operators scans their card at the SMT line, the
machine (s) would be disabled since they did not pass or go through the ESD
check.
If that sounds like a crazy idea, what are other factories doing to ensure
every operator has been checked for proper ESD compliancy within ESD
controlled zones?
Thanks,
Jim
