Hi Mike,

I used the AltaVista to find the following links for you....

..... Hole "tenting" is available through the via-cap process in which
PC401®, a thermally cured epoxy, is screened over the holes to be tented,
after liquid photo-imageable soldermask is applied. This is an advantage for
vacuum applications after assembly......

Have a wonderful day

Very Best Regards
