Hi Marie, I agree with the replies you've receive so far, however if your process is using a water soluble flux which is being aqueously cleaned, perhaps you can try the water soluble type of temp mask and have the cleaner remove it. Keep in mind there are different kinds of temp mask and they should be evaluated to verify they are not clogging up your filters and cleaning chambers.
 
Good luck

Subject: [TN] Liquid Mask

I am looking for some feedback.  We use Techform Liquid solder mask (peel able) to cover PTH on our PCA's.
We also use this Mask as a "Tacking" mechanism to hold Loose Loaded (unsecured/not bent) components on the top side of the board.  After the mask dries, we take it off the board.  This is a Non-Value added activity that I would like to eliminate.  I want to leave the dried masking on the board. 
My question is.  Can I leave it on the board?  Will it affect the long term function of the board?  Do any of you use this, or do this?  Any input is appreciated.
Thanks
Marie
