We did, I assume they still do: 68 to 78 degrees F 40% to 60% RH. Most times it was between 70 and 75 and 45 to 55 percent RH. 24/7 Chart recorder verified in three locations. SMT Lab, Wave Solder and hand solder/test areas. The worst times of the year were spring and fall. When it is 75 degress outside and 70% RH. > -----Original Message----- > From: TechNet [mailto:[log in to unmask]] On Behalf Of Henry Rekers > Sent: Wednesday, October 02, 2002 3:24 PM > To: [log in to unmask] > Subject: [TN] Temp Humidity Control - Do you? > > > How many of you out there are in full control of your > temperature and humidity in your SMT facility? > > Do you track it? > > How tight do you control temperature? > > What do you use to control humidity? > > Any info would greatly help.
