How about plugging the via with a temporary solder mask or coving them with thermal tape?

Here you go: * http://www.engineeringlab.com/soldermask1.html * http://www.circuitrework.com/guides/2-4-1.shtml ... or just go to Walgreens, buy some finger nail polish, and paint all the via with the polish.

Thanks, I guess I was making this harder than what it is. I don't know why I did not checkout Circuit technology Center's website. I have been there before.

So, this fine designer thinks the cost of you putzing around with is thing is cheaper to the comapny? No. The fine designer is measured on in-bound cost, but not on the impact on overhead of those in-bound costs. OK, try this one: Have your fabric

So next time that you order boards from your fabricator, consider asking the your fab to cap these pesky via on the solder side with SR1000 [or whatever they think will be good and cheap]. Think of the money you'll save. Your boss will be ecstatic!!!

Continuing with the idea of capping the via with SR1000: If you have boards in-stock that will require all the putzing around that you've doing to prevent the solder flowing through the via, consider reworking your stock with SR1000 to prevent all th

Just to update. I tried using the temporary solder mask again and it worked great. I guess the first time I did not let the mask to cure long enough. Also, I inquired about have the via's plugged with SR1000 in the future and I was told by our PCB

Fortunately, I only have one more set of boards left. I may or may not have to assembly, I have not gotten the word yet. Anyway, it would be good to know how to rework the boards with SR1000. I usually do not have any input when design team spins a
