Which is best: Epoxy or Vinyl and Conductive or Dissipative?

Q: We are removing old vinyl tile and replacing with ESD protective tile. We are wondering if ESD conductive or dissipative is best. Our business is dehydration baking, final functional testing and packaging semiconductor IC’s with design circuits typically in .25 micron range. We need recommendations on conductive vs. dissipative and epoxy vs vinyl tile. The area is not high traffic. Thanks.

A: Good questions. In selecting an electrical range there are several key factors to consider, these are in order of importance in our professional opinion:

1. Device sensitivity?
2. Does the type of work being performed in the protected area include, working with Power Supplies?
3. Is your staff going to be wearing personnel grounding protection?
   • ESD Shoes
   • Heel Straps
   • ESD Booties
   • Etc.
4. Are there any environmental conditions to consider?
5. How important is meeting industry standards to you and your company? e.g.
   • EOS/ESD S7.1
   • ANSI/ESD S20.20
   • ISO Compliance
   • In-House Standards
   • Customer Contract Standards

Based on what you have described in you e-mail, conductive range is best suited for your application, dissipative should not be considered. See the attached white paper on this specific subject. As this particular document has even been published yet, please keep this document confidential for your internal use only.

The factors that should be considered in choosing a Material Type are as follows:

1. What is the intended use for the floor? What type traffic will the floor see? Will liquids or spills be anticipated or utilized in this area? Do you own or lease the building? Will odors be a problem during the installation process? Are you fully operational and or will the work be done in phases? Budgetary factors Performance warranty Maintenance level expectations
2. Esthetics

I think this will give you some things to consider moving forward. Please see the attached floor comparisons chart for additional things you should consider, this chart may prove helpful to you and your team.
