I never could understand anyone investing lots of money on tile,epoxy or rubber flooring when they simply rent the building. If you own it, well thats a different story. The above esd products are expensive yet extremely durable. If your going to ren

for years we have all delt with the choices of endless products to use as flooring to create an ESD safe area for electronics assembly, I have spoke with "ESD TECH's" in the past that have told me a "clean / Bare concreate floor" provides as much di

Confirm the source of the issue. Run a coalescence test on both lots of paste. A simple coalescence test can quickly determine the condition of solder paste after prolonged use. Simply print a small disk [around 4-5mm diameter and 0.2mm thick - a bu

Appreciate all the replies. We have a good system in place with ESD tile floor, grounded systems/benches/etc and heel and wrist strap usage and monitoring. Good training program as well. We've recently upgraded to the 2007 version of the ANSI 20.2

Hany, John is right! How do I know cause I have a metal wire floor. I was faced with the same problem you are faced with now and the price was up there. I had one advantage, My floors where raised wood when we got the shop. This reduced the fati

Hi I am in favor of the best money can buy tiles, and everything including an ESD officier and training for everyone. Long term less money is spent and ESD protection is kept high continually. Boy do I have stories like the cleaning guys who put on

Just have everyone where a smock. Seems to do little for ESD but everyone buys into it. Finger cots will add more flare as well. Wet concrete works the best for flooring, but seems to have a tendency to dry, thus losing it conductivity. Therefore

I have never seen any industry standards for setting up an SMT assembly facility, but I�ll offer some basic advise. An ideal SMT assembly facility is one that is clean and well lit and has environmental controls to maintain temp and RH. Temp of 24C (

We're not sure of the condition of your solder paste. So, afte 24 hours, if it's: * Unused, in a reclosed container, maybe a week of life depending on the environment * Used, scrap A simple coalescence test can quickly determine the condition of sol
