Update - Solved On talking with BTU they mentioned that if the conveyor is always running full speed then cleaning out the motor brush area with compressed air will cure it. I'm guessing that the carbon dust had encroached onto the encoder. A good b

If it is "wondermask" made by Techspray, it is supposed to be water soluble. It being overcured (we have experienced this before), water will not touch it. We used acetone which softened it up to remove it with an orange stick. We apply it ourselves

Most RTV's depend on atmospheric moisture to cure. You can put them in an oven with a pan of water and that will speed up the cure. I'd suggest about 150 to 180 degree F, time period to depend on the thickness of the RTV. You'll have to do some tests

All, Can anyone point me in the right direction for (sources of info) various ways to quickly cure RTV or atleast speed up the process. Our requirements are to use Dow Corning 3145 hi-temp RTV. I have tried contacting the manufacturer but am losing

Some people run underfill through their reflow oven set with a normal recipe, but at breakneck speed. We think that might not produce the cure that we'd like to obtain. We'd don't use our reflow oven because we don't want to given-up the time to

Hi: I have seen this problem before. It is caused by improper curing of solder mask by the fab manufacturer. When you run the board thru' wave solder, and then wash the board, you see the problem of white residue. However, when you apply heat, you c

Some thing to watch out for is the cure spec for the adhesive. Will that match with your solder paste reflow spec? You will have two dissimiliar materials going through endothermic reactions at the same time. You could end up with under cured adhesiv

Sal, Jax has a good point about utilizing your multi-profile oven and switching to a different profile. However, since some ovens cause trouble while cooling off and stabilizing, I will assume you do have to use the same profile for whatever reason.
