Thanks to those that replied.  Some were quite funny and there are some days I wish we could implement a few of those ideas. :-)

Richard,

I'm aware of continuous monitors for wrist straps but not a continuous monitor that would check the ESD shoes and operator connection?  What systems are you referring to.  You can email me offline if you don't want to get into specific suppliers/products.

Thanks,

Jim

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
