Resistivity [1/ohm] readings are determined by the "cleanliness" that you desire to ensure the proper performance of your product. Check the fine SMTnet Archives for background. Contact USFilter [ http://www.usfilter.com/ ] for help.

I would like to Add that Mitch is very knowledgeable on this subject, I believe since 2008 this has been a topic of his .. different of low temp baking 40c 50c 60c vs 90c or 125c I do have some totech independent evaluation on the subject if you lik

Hello, we use an oven to dry our MSL components after the floor lifes expires. The oven works at 40°C / 0.1% RH. The plan is to upgrade the oven from 40°C to 60°C to shorten the duration of the process. I have found a number of articles mentioning

My company is an ESD firm. I have tested many different floors and sell ESD flooring and other products. With that said, here are my thoughts. Unsealed concrete is porous and tests in the 10 6th-8th range here in the southeast where we have decent hu

We are setting up a facility in China and would like to verify the resistivity reading on our Westek wash machine. The only tool we have at this time is a multimeter. The machine reads .570 Mohms and the MM reads around .25 Mohms at a probe distance

Hi Andrzej, I guess you mean peelable solder resist. Good idea to try during R&D, but certainly not a solution on production floor. Also, few constraints to be considered such as presence of entrapped air between component and solder resist, the natu

We have concrete floors. We check 28 locations every 90 days with a surface resitivity meter (calabrated) and Ive never seen a reading other than 10 to the 9th

HI Friend, My SMT Production Floor RH reading are 38%RH to 65%RH. It is within control or as per IPC/J-STD or orthers industries standard recommendation? Hope to hear comment from anyone. Thanks!
