Pavel You're correct that you should consider the point loading of your placement, wave and other machines. I've put shops above the ground floor of buildings. Equipment suppliers are the best source of information about these requirements. BR, dav

Davef, Could you tell me if you filled your floor by additional concrete layer during your shop construction? Have you had any placement machines stability issues? Your input would be really valuable. Thank you.

Colleagues, Now I am involved into plant ramp-up where 3x Panaconic NPM-W will be installed. New production hall is being designed right now and the problem is that constructors have never met SMT shops and know very few or next to nothing about requ

Jim, Thank you for the input. Could you please check your standard filter pore size? A model number would be valuable. How many shop volumes (in cubic meters) do you pump per hour? Customer is seriously thinking over installing AC system similar to

I can't answer your specific question on the floor, but I have some suggestions. The equipment manufacturer should be able to provide the floor loading requirements. A structural engineer should be able to translate that into specs for hte constructi

Davef, Thank you. I wonder if you have ever faced with concrete layer thickness selection for SMT shops? All I have found refers to metal treatment shops (primarily milling & drilling). 6" concrete is thick enough for them to stabilize milling machi

Vinyl ESD floor tiles are probably the most expensive approach to "permanent" flooring, about $8 a square installed. VPI and 3M are reputable suppliers. Let me digress on ESD floor "waxes", the earlier poster�s comments are well taken, but the bigge
