The HumiSeal 1B31 is actually pretty fast drying e.g. 24h @ room temperature or 30min @ 76 °C Link

Chrissie, This varies widely by paste, room temperature, and humidity. You would need to do a DOE for you exact set-up. Since you say the room is uncontrolled you need to keep in mind that time will drop as temperature goes up. Different pastes re

| Hi All, | Any one experince BGA-chipset warp about 10-15mil after removing | from PCB? | FYI, the rework temperature for preheat was 170C from room | temperature about 30 seconds, & BGA was removed at temperature | between 190-200C. | Thankyou.

AL, Let's always remember that any Temperature controlled environment has to draw higher Time to bring the Temperature down than that is drawing for Temperature Ramp up. The best way is to keep Room Temperature in as low as possible level & open t

The viscosity is only consistent over a small temperature range. If your room temperature has changed by a few degrees, it can make all the difference. You may have to increase the settling time. We did not check the viscosity, but measured the con

I have difficulty to convince my management to air-condition our manufacturing facilities. The room temperature fluxuates from 8 deg.C in the morning to 25 deg. C in the afternoon. The PCB topside temperatures in the reflow oven and wave soldering ma

It depends, but I'd guess that as a minimum the floor clock will start when the component returns to room temperature. It's easy to argue that the floor clock starts earlier than that!!! Probably, the floor clock starts a couple degrees lower than th

Not sure why you'd want to immerse an assembled board in 60-70*C IPA for an hour, but I doubt there is much published material on the topic * IPA is toxic * IPA is flammable at room temperature and heating IPA to 60-70*C only makes it more so * There

We need to dry and clean the air in our dedicated poting and conformal coating room. Can anybody help on how to go about it. The airconditions only recycle and dry until room temperature is reached and therefore have great fluctuations and unstable p
