The follwing is from the Technet archives, per IPC's Jack Crawford. I dug it up during some investigation of a supplier's issues with humidity in an Asian plant: There is support for this in IPD-HDBK-001 w/Amendment 1 Handbook and Guide to Suppleme

No, but we find discussions about relative humidity fairly short sighted, because relative humidity is such an imperfect measure of the amount of moisure in the air. Dew point is much more appealing. R.H. = (amount of moisture)/(maximum amount that

Jack: You should use your components promptly. Don't store 'em, only bad things will happen to them. 1 You should store all your components, not just your SMD reeled components, so they are not damaged or their solderability decreased. Check the

3 Printer Area Conditions * As stated earlier, heat and humidity are damaging to solder paste. Ideally, the printing area should be maintained at 40% - 50% relative humidity and 72°- 80°F (22-26°C). In addition, no air (cool or warm) should blow dire

I have problems with blowholes during the wave soldering process. I already find out that the stock time between reflow and wave is the most important. The longer the boards are in stock the more blowholes we have. We don't have a climat controlled
