All, What controls do you have in place for PCB moisture control? If you had a kit of 400 and you ran out of a part which wasnot due in until 6 weeks- do you store the boards in a dry cabinet ? Vacuum seal and store on a rack? Alan...

AJ, We use all ENIG boards. After opening, any remaining boards are kept in low humidity keeping cabinet. I have never experienced a problem using this method I think the longest I have kept them this way is eighteen months. We also store any open tr

You might want to try baking the LED's in an oven for 24 hours prior to build. We keep our LED's in a humidity cabinet all the time, as we have noticed poor solderability if they are left out for too long. This may be even more important when buying

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

Hi, I ran a clean room once, and the humidifiers were built into the exit air ducts, and controlled by a humidity control unit that kept things at 60%. We were loading VHS tapes, and needed to keep humidity at that level or static discharges caused

I don't think the syringe pressure has been adjusted, but I'll watch over the next few days to see if it changes (by itself of course). We don't control the humidity in our plant and don't really track it. However, there have been some significant

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

Hi, If you need to get a humidity target, the best way is to run the air conditioning plant very cold, which will drop the moisture out of the air, and then you can reheat to the required temp, and install humidifiers to re humidify the air to the r

The paste dispensers work well as long as the humidity in your shop is properly controlled. If it gets too humid, and the paste gets "soupy", then it will take less air pressure to dispense it onto the stencil. Paste dispensers use a controlled, pre-
