摘要 |
A screening mask for screening an article, the screening mask including a screening mask body having a screening side and a nonscreening side, an one opening through the mask for screening at least one feature from the screening side to the nonscreening side, and a blind opening for protecting a previously screened feature. The blind opening is blocked on the screening side and open on the nonscreening side. The screening mask is used in double pass screening so that a second feature may be formed on the article without damaging a previously formed feature.</PTEXT>
