Hello there: Currently we are building our own facility for producing electronic assemblies. I had a long discussion with my colleagues concerning the ESD mats surrounding the sensitive components areas such as the pick & place machines, rework & repair, etc. One of the suggested ideas was to use thin metal sheets in combination with ESD foot straps for the operators.
Now I ask if this is accepted technically or not. The reason for this question is the very high prices of the ESD mats.
