Lower RH = more static build-up on production floor = greater chance of ESD damage to product. Primarily, I think your SMT print job can be affected by RH which could cause defects like the ones you mention. Look at ANSI/ESD S20.20 for more info an

J-STD-001 doesn't necessarily require additional controls under conditions of low humidity, only that you verify the effectiveness of what you have in place. ESD S20.20 [1999] only says that relative humidity above 30% is "desirable". ESD S20.20 [200

Here in the Great White North, the best way to check our CM's compliance with the ESD 20.20 is to take a couple months worth of data during heating season and graph it against the outside temp swings. You can easily see how the HVAC system keeps up,

Hi all, We are looking at putting cutting boards into our goods in area - for opening sealed bags to check the contents and to aid in decanting, and would appreciate any relevant input. The components should never come into direct contact with thes

Hi all, We have been trying to improve our current levels of ESD control in our SMT manufacturing area, while carrying out a initial audit I have found that we have two different grounding planes. One for the electrical grounding through mains powe

2K at 12 inches seems high considering that degradation can take place at anything over 200v. If I recall correctly we required at least 3 feet of distance. It's been a while since I've been an ESD coordinator. Thank god that chapter in my life
