Low humidity control

Electronics Forum | Wed Feb 02 06:58:07 EST 2011 | mikeyjryan

Hello, The company I work for are located in the North of Spain and the humidity levels in the factory range from 10 to 60 %RH. We have concerns about the low humidity effects on our ESD controls and want to invest in a system to keep the humidity a

90%) from the sample, and the bake time and temperature specified herein are minimums. To improve test accuracy, or to prevent heat damage, other bake parameters may be AABUS. 2 Applicable Documents IPC-QL-653 Certification of Facilities that Inspect

How does temperature and humidity effect solder paste/printing

OA pastes are more hydroscopic than NC pastes. Hydroscopic. The capacity of a material to absorb and retain moisture from the ambient air. Sometimes this is compounded if you remove paste from the frig and let it warm to room temperature, because

Would rather have lower humidity and strict ESD rules in place.. than a high humidity condition anyday.. High humidity- 45RH + Paste depending on what you use may become an issue.. Components are sensitive... ever get that vacuum sealed bag you dont

J-STD-001 Par 4.2.2 Temperature and Humidity

Per ESD Handbook TR 20.20 paragraph 5.3.15 Humidity "Humidity is beneficial in all ESD Control Program Plans. Contact and separation of dry materials generates greater electrostatic charges than moist materials because moisture provides conductivity

ESD QUESTION

Latex is not a conductor. It's an insulator. So, it will not conduct a charge to the metal wire rack. You can test this hypothesis by charging a latex tube in the shop and measuring its conductivity to ground. We believe that you should not have

J-STD-001 Par 4.2.2 Temperature and Humidity

Electronics Forum | Mon Jul 16 15:44:27 EDT 2007 | davef

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

Without being clear on whether you're talking about: * Standard air knives at the back-end of your in-line cleaner ... OR * Hand held or similar nozzle. Standard air knives: This causes no problem with ESD because the relative humidity is so high t
